SECTION 1: PLANS CONTENT

History of Development to Date

The Olympus Development will consist initially of a new 24 slot tension leg platform (TLP) and a six slot 

subsea field tieback to the TLP. 

The drilling and completion of the six slot subsea tieback was previously covered under Initial Exploration 

Plan for MC 762, 805 and 806 Control No. N-09570 approved July 11, 2011. The 24 well batch set for the 

TLP and the drilling of the first well (MB 001) to total depth was previously approved under Supplemental 

Exploration Plan for MC 762, 763, 806 and 807 Control No. S-07499 approved November 22, 2011. 

This initial DOCD will cover the installation of the subsea tieback including umbilicals, flowlines, manifold, 

plets, UTAs and flying leads necessary to produce the subsea wells, the drilling and completion of the other 

24 DVA wells, and the installation of the 24 slot TLP and associated topside equipment necessary to produce 

the DVA and subsea wells.

Shell‟s plan, as detailed in this DOCD, is to use a platform based drilling unit, the Shell N88, or equivalent rig 

(the “rig”), to complete the DVA wells which are located approximately 53 miles from the nearest coastline 

(Louisiana), 91 miles from the supply base at Port Fourchon, Louisiana, and 82 miles from the helicopter 

terminal at Boothville, Louisiana. Water depth at the well site surface locations is 3,030 feet. The schedule

proposed in the following form BOEM-137 to drill and complete the wells is an estimate based on the best 

available information regarding downhole conditions likely to be encountered and is not intended to be a 

limitation. Installation of subsea equipment is planned to begin November 20, 2012 and will be accomplished 

with a non-anchored pipeline lay barge supported by tug boats, supply vessels and helicopters as detailed in 

Section 14 of this DOCD. 

The offshore installation of the Olympus TLP begins with Pile transportation and installation in Mississippi 

Canyon Block 807 in approximately 3030‟ of water. The 16 Piles are 96”O.D. and about 431‟ long. They will 

be driven in clusters of 4 at the four corners of the TLP foundation using a MHU-500T hammer off the 

Installation Vessel similar to past Shell TLP installations.

Upon completion of the Pile Installation scope, 16 Tendons will be transported to the Olympus site for 

assembly and installation. Assembly of the Tendons consists of upending each section and arranging the 

section vertically using a platform off the side of the Installation Vessel. The make-up of the Tendons 

includes a Bottom Section, multiple Main Body Sections and a Top Section. Each section is assembled using a 

connector similar to past Shell TLP Installations. The Tendons are connected to a specific Pile using a 

latching mechanism similar to past Shell TLP Installations. The Tendons each be free-standing using Tendon 

Support Buoys, which are removed after the TLP is fully tensioned.

At approximately the seventh Tendon installation, the quayside integrated Hull and Topside will be wet towed 

from Corpus Christi to the Olympus Site. The inland tow will commence with two inland tugs as steering tugs 

breasted to the TLP, two offshore tugs as push tugs breasted to the TLP, two inland tugs as break tugs 

connected with hold-back lines to the TLP, an offshore tug as an escort leading the convoy and an offshore 

tug as an escort trailing the convoy. At the sea buoy, the four inland tugs will be released, three of the 

offshore tugs will be attached to the TLP and one offshore tug will travel as an escort.

The TLP will arrive at the Olympus Site and final preparations will begin for the connection to the Tendons.

The four offshore tugs will connect to four sides of the TLP to position the TLP over the Tendons. The TLP 

will commence ballast so that the Tendons will connect to the TLP then the ballast will be removed to create 

the required tension. The Flare Boom will be lifted and installed along with completions activities for the 

Installation Contractor to remove installation aids.

The TLP tendon piles and wellsite plat is included in this plan. The unlabeled red box symbols to the west and 2 

places on north represent future riser porches.
The rig Shell plans to use for the well completion of the DVA wells is a platform based rig and is equipped with 

state-of-the-art drilling and well control equipment. The rig will comply with the requirements in the Interim 

Final Rules. The completion activities will be supported by the support vessels and aircraft as well as onshore 

support facilities as listed in Sections 14 and 15 of the DOCD. Shell has employed or contracted with trained 

personnel to carry out its exploration activities. Shell is committed to local hire, local contracting and local 

purchasing to the maximum extent possible. Shell personnel and contractors are experienced at operating in 

the Gulf of Mexico and are well versed in all Federal and State laws regulating operations. Shell‟s employees 

and contractors share Shell‟s deep commitment to operating in a safe and environmentally responsible manner.

Shell, through its parent and affiliate corporations, has extensive experience safely developing for oil and gas in 

the Gulf of Mexico. Shell will draw upon this experience in organizing and carrying out its planned MC 807

completion program. Shell believes that the best way to manage blowouts is to prevent them from happening. 

Significant effort goes into the design and execution of wells and into building and maintaining staff 

competence. In the unlikely event of a spill, Shell‟s Regional Oil Spill Response Plan (OSRP) is designed to 

contain and respond to a spill that meets or exceeds the WCD detailed in Section 9 of this DOCD. The worst 

case discharge (WCD) does not take into account potential flow mitigating factors such as well bridging, 

obstructions in wellbore, reservoir barriers, or early intervention. Shell continues to invest in Research and 

Development (R&D) to improve safety and reliability of our well systems. All operations will be conducted in 

accordance with applicable federal and state laws, regulations, and lease and permit requirements. Shell will 

have trained personnel and monitoring programs in place to ensure such compliance.

C. SAFETY AND POLLUTION FEATURES:

The rig we plan to use, the Shell N 88 or similar, will comply with all of the regulations of the American Bureau 

of Shipping (ABS), International Maritime Organization (IMO) and the United States Coast Guard (USCG). All 

drilling operations will be conducted under the provisions of 30 CFR, Part 250, Subpart D, and other applicable 

regulations and notices, including those regarding the avoidance of potential drilling hazards and safety and 

pollution prevention control. Such measures as inflow detection and well control, monitoring for loss of 

circulation and seepage loss, and casing design will be our primary safety measures. Primary pollution 

prevention measures are contaminated and non-contaminated drain system, mud drain system, and oily water 

processing.

The TLP, subsea facility, and lease term flowline system will have the following features:

 The production facility will have drip pans under hydrocarbon equipment to minimize the potential loss 

of fluids through grated openings. The facility will utilize an open drains system as the primary control 

of potential spills. Lube oil drains will be piped into a separate closed drain system. The deck open 

drain system is designed to collect and contain rainwater, runoff, and liquid spills in drip pan areas. It 

is operated as an atmospheric drain system. Drainage will be routed via segregated hazardous

(flammable) and non-hazardous deck drains systems. Hazardous drains go to an open drain Pre-Sump 

(separator); separated water is routed to the Sump Caisson. Skimmed oil will be recovered and 

returned (pumped) to the process. Non-hazardous drains go directly to the Sump Caisson. All fluid 

containing vessels will have drain valves and drip pans to control and collect any potential spill as a 

result of maintenance activities. Roof drains (strictly rainwater) are piped directly overboard.

 Produced water will treated by hydrocyclone followed by flotation cell for overboard disposal. The 

design maximum dispersed oil in water specification is consistent with the statutory limit of less than 

29mg/l but will endeavour to achieve a limit of 15 mg/l.
 In the event of an emergency, the topsides facility has a blowdown and shut-down system designed 

to isolate and depressurize hydrocarbons in order to limit the amount of inventory exposed to the 

event. Upon fire or confirmed gas detection, emergency shutdown valves strategically located to 

isolate critical topsides equipment will isolate the process. The emergency shutdown system also deenergizes rotating equipment (compressors, pumps, etc.) which limits any discharges emanating from 

these sources. If necessary a blowdown system can be activated to de-pressure the topsides via the 

flare system and limit the gas inventory in process vessels. The blowdown is capable of depressuring 

the facility to 100 psi in 10 minutes.

 The hydrocarbon (diesel) storage tanks in the hull will have level indicators and high level switches 

designed to monitor and prevent overfill of the tanks during filling operations.

 

 Subsea equipment will be provided with pressure indicators to detect an upset condition. Provisions

have been made for installing remotely operated valves at the tree and manifold capable of isolating 

each piece of equipment and limit the amount of a spill in the event of loss of containment.

 The oil and gas export pipelines each have a departing valve located immediately downstream of the 

gas sales meters and oil sales pumps. The departing valves are remotely operated and tied to the 

emergency shutdown system

 The sewage collection and treatment system is designed to work efficiently at maximum occupancy 

and comply with statutory regulations. Sewage will be treated in a USCG Type II marine sanitation 

device and disposed into the sea. Provisions shall be incorporated to treat the sewage effluent through 

a macerator with supplemental chlorine injection when the USCG Type II MSD is being serviced.

E. Pollution Prevention Measures

In addition to the measures discussed in 1c, the gas and oil export pipelines will be fitted with a secondary 

isolation device to supplement the departing valves. These remotely operated valves will be located on the 

hull pontoons, directly upstream of the stress joint. These secondary isolation valves will also be manually 

actuated, and will isolate the gas and oil export lines at this secondary location to limit the inventory which 
could reverse flow through the pipeline network back through the facility in the event of a leak downstream 

of the primary departing isolation valve.

DRAIN SYSTEM

Drains are provided on the platform rig in all spaces and on all decks where water or oil can accumulate. The 

drains are divided into two categories, non-contaminated and contaminated. All deck drains are fitted with a 

removable strainer plate that prevents debris from entering the system.

Deck drainage from rainfall, rig washing, deck washing, and runoff from curbs and gutters, including drip 

pans and work areas, are discharged depending on if it comes in contact with the contaminated or noncontaminated areas of the platform rig.

1) Non-contaminated Drains

Non-contaminated drains are designated as drains that under normal circumstances do not contain 

hydrocarbons, and can be discharged directly overboard. These are mostly located around the main deck and 

outboard in places where it is unlikely that hydrocarbons will be found.

2) Contaminated Drains

Contaminated drains are designated as drains that contain hydrocarbons and cannot be discharged 

overboard. We have two drains, one for oil contaminated water routed to the rig sump and one for clean 

water which is routed overboard. In the areas where a spillage of oily water or hydrocarbon is possible, the 

operator will make the decision on where to route the spillage. Oil is routed to the drilling sump, other 

contaminates are cleaned up and placed in approved containers to be sent to shore for proper disposal.

3) Mud Drain System

• Mud Pump Rooms - have a vacuum system to collect mud from the pump room and either send it in for 

reclamation or be put back into the system. The room is a containment system and anything collected will be 

managed as deemed appropriate. 

• Sack Storage Room - This is a containment area. The drains can be routed to the sump. Normal condition 

for this area is plugged drains.

• Shale Shaker Room - The shakers are on an open deck. The mud is contained and the drains from the 

deck are piped overboard.

4) Oily Water Processing (Drill Sump)

The oily water is initially routed to the Drill-Sump. The tank has sufficient residence time to allow for natural 

separation of oil and water. The oil leg is manually drained to the Production sump after it has been tested 

for anything that will emulsify the oil and flip the system or other marine pollutants. The water leg in the 

separator is routed to the overboard line.

The drill dump is a chambered weir system. The first chamber accepts the contaminated water through an 

inlet in the lower portion. This chamber allows any solids to fall out and the liquid weirs over the top to the 

second chamber. The second chamber is the largest and provides separation time. The clean water exits out 

the bottom of the chamber through a U-Tube and goes overboard. The oil weirs over the top of the second 

chamber into the third and is pumped out to the production sump. 

All discharges will be in accordance with applicable NPDES permits. See Section 18, EIA, Section C.1.2, Water 

Quality.
Drain, Effluent and Waste Systems

• The platform rig‟s drainage system is designed in line with Shell‟s environmental and single point 

discharge policies.

• To prevent migration of hazardous materials and flammable gas from hazardous to non-hazardous areas, 

the drainage systems are segregated.

• The platform rig drainage systems potentially exposed to hydrocarbons tie into the rig sump to remove

hydrocarbons that could harm the environment. 

Rig Floor Drainage

The platform rig floor drains either go to the rig sump (if they are exposed to equipment or well bore fluids) 

or directly overboard for deck drainage.

Operating configurations are as follows:

• The overboard drilling\completion fluid tank piping is double valved and normally locked closed.

• The drill sump water overflow valve is normally opened.

• The waste oil pump is capable of pumping down the oily water collection tank to the off-loading 

station (either to portable tote tanks or to supply vessel).

• The solids control system is capable of being isolated for cuttings collection. 

F. Additional Measures

 HSE (health safety and environment) are the primary topics in pre-tour and pre-job safety meetings. 

The discussion around no harm to people or environment is a key mindset. All personnel are reminded 

daily to inspect work areas for safety issues as well as potential pollution issues.

 All tools that come to and from the rig have their pollution pans inspected, cleaned and confirmation of 

plugs installed prior to leaving dock and prior to loading on the boat.

 Preventive Maintenance of rig equipment includes visual inspection of hydraulic lines and reservoirs on 

routine scheduled basis.

 All pollution pans on rig are inspected daily.

 Containment dikes are installed around all oil containment, drum storage areas, fuel vents, and fuel 

storage tanks.

 All used oil and fuel is collected and sent in for recycling. 

 Every drain on the rig is assigned a number on a checklist. The checklist is used daily to verify drain 

plugs are installed.

 All trash containers are checked and emptied daily. The trash containers are kept covered. Trash is 

disposed of in a compactor and shipped in via boat.

 The rig is involved in a recycling program for cardboard, plastic, paper, glass, and aluminum.

 Fuel hoses and SBM are changed on annual basis.

 TODO spill prevention fittings are installed on all liquid take on hoses.

 Waste paint thinner is recycled on board with a solvent still to reduce hazard of shipping and storage.

 All equipment on board utilizes Envirorite hydraulic fluid as opposed to hydraulic oil. 
 Shell has obtained ISO14001 certification.

 Shell uses low sulfur fuel to reduce air pollutant impacts.

J. Blowout scenario

Summary

This Section 2j was prepared by Shell Offshore Inc. (Shell) pursuant to the guidance provided in the Bureau of Ocean 

Energy Management, Regulation and Enforcement‟s (BOEM) Notice to Lessees (NTL) No. 2010-N06 with respect to 

blowout and worst case discharge scenario descriptions. Shell intends to comply with all applicable laws, regulations, 

rules and Notices to Lessees.

Shell focuses on an integrated, three-pronged approach to a blowout, including prevention, intervention /containment, 

and recovery. 

 
1. Shell believes that the best way to manage blowouts is to prevent them from happening. Significant effort goes 

into design and execution of wells and into building and maintaining staff competence. Shell continues to invest 

independently in Research and Development (R&D) to improve safety and reliability of our well systems.

2. Shell is a founding member of the Marine Well Containment Company (MWCC), which provides robust well 

containment (shut-in and controlled flow) capabilities. Additionally, Shell is investing in R&D to improve 

containment systems.

3. As outlined in Shell‟s Oil Spill Response Plan (OSRP), and detailed in EP Section 9a (ii), Shell has contracts with 

Oil Spill Removal Organizations (OSROs) to provide the resources necessary to respond to this Worst Case 

Discharge (WCD) scenario. The capabilities for on-water recovery, aerial and subsea dispersant application, insitu burning, and nighttime monitoring and tracking have been significantly increased.

The DOCD WCD blowout scenario is calculated for the MB-001 penetration of the W3.0 Gold Sand and based on the 

guidelines outlined in NTL No. 2010-N06 and subsequent Frequently Asked Questions (FAQ). Shell‟s Regional OSRP 

(updated to reflect this well) is based on MC-762 A (Olympus MB-001) as the Worst Case Discharge well. In this 

scenario, the MB-001 well is drilled with the Olympus DVA rig, has a worst case discharge volume estimate of 446,000 

bbls for the first day, and has a first 30-day average daily rate estimate of 359,500 bbls. The MB-001 penetration is 

relatively close to the W3.0 Gold reservoir‟s oil water contact, and under WCD flow, it is expected to produce water within 

the first 30 days; thus reducing the 30-day average WCD volume. Shell‟s Regional OSRP has response capabilities based 

on the first 30-day average daily rate; thus in the unlikely event of a spill, Shell‟s Regional OSRP is designed to contain 

and respond to a spill that meets or exceeds this WCD. 

The MB-001 well was also the well which was used to estimate the WCD in the previously approved Mars Supplemental

EP, MC 807, Plan S-07499. However the WCD blow out scenario outlined in Plan S-07499 is modeled to occur while the 

MB-001 is being drilled from a MODU drill ship (Noble Bully One), while in this DOCD WCD scenario, the blowout occurs 

while the MB-001 is being drilled by the Olympus DVA rig. Under this scenario, due to timing and scheduling constraints, 

the MB-001 will most likely not be drilled from the Noble Bully One and hence drilled from the Olympus DVA rig once the 

TLP has been installed on site. The first day WCD volume estimates from the Bully One and Olympus DVA rig blowout 

scenarios are 465,000 bopd and 446,000 bopd, respectively. The wells have essentially the same plan and design. The 

differences in the WCD volumes can be attributed to the WCD estimate from the Noble Bully One (subsea BOP‟s) modeled 

at the seafloor, while the Olympus DVA Rig‟s is modeled to the rig floor (surface BOP‟s). 

The WCD scenario, in terms of both initial and the sustained rates, has a low probability of being realized. Some of the 

factors that are likely to reduce rates and volumes, and are not included in the WCD calculation, include but are not 

limited to, obstructions or equipment in the wellbore, well bridging, and early intervention, such as containment 

capabilities.

Uncontrolled blowout rate (first 30-days average daily rate) 359,500 bbls 

Duration of flow (days) based on relief well 182 days

Table 1 Worst Case Discharge Summary

Mars B Project Overview

The Olympus Tension Leg Platform (TLP) will be located in the Mars Ursa Basin and represents an additional and 

continued development of the Mars Field. The Olympus TLP includes the installation of 24 well slots. The DOCD which 

accompanies this 2010-N06 document covers drilling all of the proposed 24 well paths and six (6) subsea wells. Based on 

the proposed well paths, open-hole intervals, and targets, the 32 well paths were assessed for their WCD potential. The 

through-salt Deimos W3.0 Gold well (MB-001) was determined to be the Olympus well with the highest individual WCD 

potential. 
The proposed Olympus TLP will be the second TLP in the Mars Field and is located approximately 53 miles east-southeast 

of the nearest shoreline in the Gulf of Mexico (GOM), in water depths of approximately 3,030 feet (ft). 

The history of the Mars Field began with the acquisition of the exploration leases between 1985 and 1988. The discovery 

well (MC-763 #1) and its appraisal by-passes were drilled in 1989. The discovery well was followed by appraisal wells 

(MC-807 #1, #2, #3, #4, and #5, and MC-806 #1), and associated by-passes and sidetracks between 1989 and 1991. 

The Mars A TLP was installed and brought onto production in 1996. The Mars field encompasses six OCS Leases in the 

Mississippi Canyon Area – Blocks 762, 763, 806, 807, 850 and 851; that are captured within the Mars Operating Unit. 

The Deimos Field is essentially „deep Mars‟, with reservoirs located below the deepest Mars production (Terra

Cotta) in a sub-salt environment. The Deimos discovery well was drilled in 2002, with the Phase I development

(three well subsea tie-back to the Mars A TLP) coming on production in July 2007. 

The Mars Field (including Deimos) is comprised of a thick sequence of stacked Plio-Miocene turbidite deposits trapped 

within the salt-flanked Mars-Ursa mini-basin. The Mars Field comprises of more than 70 individual reservoirs stacked in a 

10,000 foot sequence. 

These reservoirs include:

 Sub-salt reservoirs added to the field with the 2002 Deimos discovery.

 Six large-scale, laterally extensive and well connected reservoirs in the above-salt section which

form the targets for the current Mars A waterflood activity.

 A large number of generally shallower and smaller-scale depletion drive reservoirs.

The MB-001 well targets the W3.0 Gold reservoir. The W3.0 Gold is the principal component of the Gold reservoir, 

occurring at tvdss depths typically ranging from 20,200ft to 20,600ft within the deep reservoir fault block. It comprises a 

widespread, large-scale, high net-to-gross, amalgamated sand body, ranging from ~150ft to 250ft in true vertical 

thickness. The structural interpretation of the W3.0 Gold, together with the OWC observed at 20,442ft (tvdss) indicate 

that recoverable volumes are largely restricted to the up-dip crestal portion of the deep reservoir fault block structure. 

The MB-001 well will target the up-dip or crestal area of the deep reservoir fault block. In more down-dip areas of the 

field, the W3.0 Gold is interpreted to be laterally extensive, wet, more heterogeneous and displays systematic upwardfining grain size trend. The W3.0 Gold reservoir is expected to include a large aquifer. 

Detailed reservoir models have been constructed for all of the main Mars and Deimos reservoir horizons. The static 

reservoir models have been constructed using the full suite of subsurface data collected during the evaluation of these 

Mars and Deimos wells, and these have subsequently been converted to dynamic simulation models for history matching 

and development planning and forecasting. 

Shell‟s seismic interpretation used for constructing the Deimos W3.0 Gold reservoir model is based on high quality 

anisotropic ocean bottom nodes - wide azimuth (OBS WAZ) seismic survey. A seismic profile through the proposed MB001 well target is included as attachment K. This survey has an excellent well tie to the relevant offset well penetrations, 

thus giving a high confidence interpretation. The seismic interpretation was used for constructing the structure and 

stratigraphic framework of the model. Due to the excellent seismic to well ties, the amplitude extraction maps were 

correlated to the reservoir characteristics of each well and extrapolated across the entire area of the W3.0 Gold sand in 

the basin. These seismic extraction maps were then imported into Petrel for construction of the deterministic W3.0 Gold 

static reservoir model. The static model was then used to construct a MBAL/Prosper model for reservoir simulation. The 

MB-001 well target was simulated in this MBAL/Prosper model. Therefore the resulting WCD calculation included in this 

document is based on the reservoir properties indicated from the reservoir model at the target location. This document is 

a summary of the results of this modelling. Electronic copies of the reservoir model and its output can be provided to the 

BOEM upon request. 

For the Deimos W3.0 Gold WCD scenario, the model considered the maximum reservoir drainage area with no internal 

fault sealing or baffling incorporated and the aquifer extent modelled as per the expectation extent and magnitude.
1) Purpose

Pursuant with 30 CFR 250.213(g), 250.219, 250.250, and NTL No. 2010-N06, this document provides a blowout scenario 

description, further information regarding any potential oil spill, the assumptions and calculations used to determine the 

WCD and the measures taken to 1) enhance the ability to prevent a blowout and 2) respond and manage a blowout 

scenario if it were to occur. These calculations are based on best technical estimates of subsurface parameters that are 

derived from the offset wells, and seismic. These parameters are better than or consistent with the estimates used by 

Shell to justify the investment. Therefore, these assumed parameters were used to calculate the WCD. They do not 

reflect probabilistic estimates.

2) Background 

This attachment has been developed to document the additional information requirements for Development Operations 

Coordination Documents (DOCD) as requested by NTL No. 2010-N06 in response to the explosion and sinking of the 

Mobile Offshore Drilling Unit (MODU) Deepwater Horizon and the resulting subsea well blowout and recovery operations 

of the exploration well at the MC-252 Macondo location.

3) Information Requirements 

a) Blowout scenario 

All locations of the proposed Mars B DOCD supplement were assessed for Worst Case Discharge. The MB-001 

well represented the highest 30-day average flow potential. The MB-001 well will be drilled to the W3.0 Gold 

Sand as described above using the Olympus TLP DVA rig with a surface BOP. A hydrocarbon influx and a well 

control event are modeled to occur from the W3.0 Gold Sand during a trip out of the hole. The simulated 

blowout model results in unrestricted flow from the well at the surface which represents the worst case 

discharge, no restrictions in the wellbore, failure/loss of the subsea BOP, and a blowout to the surface.

Note: based on MBAL/Prosper Model 

Table 3 Estimated Duration and Volume of a Potential Blowout

There is usually a decline in the discharge rate as time proceeds, which is illustrated by the differences between 

the first 24-hour volume and 30-day average rate. The total volume calculated until a well is killed in a potential 

blowout further demonstrates this decline. At very short times, e.g. during the first 24 hours, the pressure profile 

in the reservoir changes from the moment when a well first starts flowing to a pseudo-steady state pressure 
profile with time, and as a result the rate declines. At somewhat longer time scales, effects such as reservoir 

voidage and the impact of boundaries can cause the rate to drop continuously with production. Simulation and 

material balance models can include these effects and form the basis of the NTL No. 2010-N06 estimates for 24-

hour and 30-day rates as well as maximum duration volumes.

d) Assumptions and calculations used in determining the worst case discharge (Proprietary)

e) Potential for the well to bridge over 

Mechanical failure/collapse of the borehole in a blowout scenario is influenced by several factors including in-situ 

stress, rock strength and fluid velocities at the sand face. Based on the nodal analysis and reservoir simulation 

models outlined above, a surface blowout would create a high drawdown at the sand face. Given the substantial 

fluid velocities inherent in the worst case discharge, and the scenario as defined where the formation is not 

supported by a cased and cemented wellbore, it is possible that the borehole may fail/collapse/bridge over within 

the span of a few days, significantly reducing outflow rates. However, this WCD scenario does not include any 

bridging or consideration of solids production with the oil and gas.

f) Likelihood for intervention to stop the blowout. 

Safety of operations is our top priority. Maintaining well control at all times to prevent a blowout is the key focus 

of our operations. Our safe drilling record is based on our robust standards, conservative well design, prudent 

operations practices, competency of personnel, and strong HSE focus. Collectively, these constitute a robust 

system making blowouts extremely rare events. 

Intervention Devices: Notwithstanding these facts, the main scenario for recovery from a blowout event is via 

intervention with the BOP attached to the well. There are built in redundancies in the BOP system to allow 

activation of selected components with the intent to seal off the well bore. As a minimum, the Shell contracted rig 

fleet in the GOM will have redundancies meeting the Interium Final Drilling Safety Rule with respect to Remotely 

Operated Vehicle (ROV) hot stab capabilities, a deadman system, and an autoshear system.

The potential for surface intervention on the Olympus TLP depends greatly on the nature of the breach, the flow 

volume, and to a lesser degree, whether the well flowed predominantly oil or gas. A relatively small leak could 

probably be managed in several different ways. Larger flows would certainly provide a greater challenge, but 

could be handled, particularly if the flow could be diverted away from the work area. In the event of uncontrolled 

flow from a Olympus TLP well, the facility would most likely be evacuated. If the structure is erect, the feasibility 

of reentering the facility would need to be assessed due to the volatile nature of the situation. In the event that 

surface intervention is possible, the Shell Well Control Contingency Plan (WCCP) document would be utilized to 

coordinate relief planning.

Containment: The experience of gaining control over the Macondo well has resulted in a better understanding 

of the necessary equipment and systems for well containment. As a result, industry and government are better 

equipped and prepared today to contain an oil well blowout in deepwater (See page 17 of the Decision 

Memorandum dated October 1, 2010). Shell is further analyzing these advances and incorporating them into its 

comprehensive approach to help prevent and, if needed, control another deepwater control incident. 

Shell is a founding member of the Marine Well Containment Company (MWCC), which provides robust well 

containment (shut-in and controlled flow) capabilities. Pursuant to NTL No. 2010-N10, Shell will provide 

additional information regarding our containment capabilities in a subsequent filing. 

g) Availability of a rig to drill a relief well and rig package constraints

Blowout intervention can be conducted from the existing drilling rig or from another drilling rig. Shell has an 

active portfolio of well operations in the GOM which will be supported by a total of four to six MODU rigs in 2012

– 2015 timeframe. The dynamically positioned rigs under contract, the Noble Danny Adkins and the Noble Bully 

1, will be the preferred rigs for blowout intervention work. However, moored rigs can also be used in some 

scenarios. Additionally, in the event of a blowout, there is the distinct possibility that other non-contracted rigs in 

the GOM could be utilized whether for increased expediency or better suitability. All efforts will be made at the 
time to secure the appropriate rig. Shell‟s current contracted rigs capable of operating at these water depths and 

reservoir depths without technical constraints are in the following table:

drill ship

Above are current as of December 2011. Future modifications may change the rig‟s capability.

* Rig capabilities need to be assessed on a work scope specific basis.

**Bully I estimated operational Q1, 2012.

h) Time taken to contract a rig, mobilize, and drill a relief well. 

Relief well operations will immediately take priority and displace any activity from Shell‟s contracted rig fleet. The 

list of Shell contracted rigs capable of operating at this location is tabled above. It is expected to take an average 

of 14 days to safely secure the well that the rig is working on; up to the point the rig departs location, and a 

further 1-4 days transit to mobilize to the relief well site depending on distance to travel. The relief well will take 

approximately 124 days to drill down to the last casing string above the blowout zone plus approximately 40 days 

for precision ranging activity to intersect the blowout well bore. Total time to mobilize and drill a relief well would 

be approximately 182 days for this well. 

If a moored rig is chosen to conduct the relief well operations, anchor handlers would be prioritized to prepare 

mooring on the relief well site while the rig is being mobilized. This activity is not expected to delay initiation of 

relief well drilling operations. Shell has 3 deepwater anchor handlers (the Laney, Dino, and Ross Chouest) on long 

term contract to support its moored rigs. 

The closest TLP to the Deimos reservoirs is the Mars “A” TLP. Currently there are no slots available for drilling a 

new well (relief well) from the Mars “A” TLP; and Mars “A” TLP‟s DVA rig is not capable to technically to drill a 

MB-001 relief well. Therefore the only way to initiate the drilling of a relief well is with a MODU.

i) Measures proposed to enhance ability to prevent blowout and to reduce likelihood of a 

blowout.

Shell believes that the best way to manage blowouts is to prevent them from happening. Detailed below are the 

measures employed by Shell with the goal of no harm to people or the environment. The Macondo incident has 

highlighted the importance of these practices. The lessons learned from the investigation are, and will continue to 

be, incorporated into our operations.

Standards: Shell‟s well design and operations adhere to internal corporate standards, the Code of Federal 

Regulations, and industry standards. A robust management of change process is in place to handle un-defined or 

exception situations. Ingrained in the Shell standards for well control is the philosophy of multiple barriers in the 

well design and operations on the well. 

Risk Management: Shell believes that prevention of major incidents is best managed through the systematic 

identification and mitigation process (Safety Case). All Shell contracted rigs in the GOM have been operating with 

a Safety Case and will continue to do so. A Safety Case requires both the owner and contractors to systematically 

identify the risks in drilling operations and align plans to mitigate those risks; an alignment which is critical before 

drilling begins. 

Well Design Workflow: The Well Delivery Process (WDP) is a rigorous internal assurance process with defined 

decision gates. The WDP leverages functional experts (internal and external) to examine the well design at the 

conceptual and detailed design stages for robustness before making a recommendation to the management 
review board. Shell‟s involvement in global deepwater drilling, starting in the GOM in the mid-1980‟s, provides a 

significant depth and breadth of internal drilling and operational expertise. Third party vendors and rig 

contractors are involved in all stages of the planning, providing their specific expertise. A Drill the Well On Paper 

(DWOP) exercise is conducted with rig personnel and vendors involved in execution of the well. This forum 

communicates the well plan, and solicits input as to the safety of the plan and procedures proposed.

Well and rig equipment qualification, certification, and quality assurance: All rigs will meet all 

applicable rules, regulations, and Notice to Lessees. Shell works closely with rig contractors to ensure proper 

upkeep of all rig equipment, which meets or exceeds the strictest of Shell, industry, or regulatory requirements. 

Well tangibles are governed by our internal quality assurance/control standards and industry standards.

MWD/LWD/PWD Tools: Shell intends to use these tools at MB-001. The MWD/LWD/PWD tools are run on the 

drill string so that data on subsurface zones can be collected as the well advances in real time instead of waiting 

until the drill string is pulled to run wireline logs. Data from the tools are monitored and interpreted real time 

against prognosis to provide early warning of abnormal pressures to allow measures to be taken to progress the 

well safely. 

Mud Logger: Mud logging personnel continually monitor returning drilling fluids for indications of hydrocarbons, 

utilizing both a hot wire and a gas chromatograph. An abrupt increase in gas or oil carried in the returning fluid 

can be an indication of an impending kick. The mud logger also monitors drill cuttings returned to the surface in 

the drilling fluid for changes in lithology that can be an indicator that the well has penetrated or is about to

penetrate a hydrocarbon-bearing interval. Mud logging instruments also monitor penetration rate to provide an 

early indication of drilling breaks that show the bit penetrating a zone that could contain hydrocarbons. The mud 

logging personnel are in close communication with both the offshore drilling foremen and onshore Shell 

representative(s) to report any observed anomalies so appropriate action can be taken.

Remote Monitoring: The Real Time Operating Center has been used by Shell to complement and support 

traditional rig-site monitoring since 2003. Well site operations are lived virtually by onshore teams consisting of 

geoscientists, petrophysicists, well engineers, and 24/7 monitoring specialists. The same real time well control 

indicators monitored by the rig personnel are watched by the monitoring specialist for an added layer of 

redundancy. 

Competency and Behavior: A structured training program for Well Engineers and Foreman is practiced, which 

includes internal professional examinations to verify competency. Other industry training in well control, such as 

by International Association of Drilling Contractors (IADC) and International Well Control Forum (IWCF) are also 

mandated. Progressions have elements of competency and Shell continues to have comprehensive internal 

training programs. The best systems and processes can be defeated by lack of knowledge and/or improper 

values. We believe that a combination of HSE tools (e.g. stop work, pre-job analysis, behavior based safety, 

DWOPs, audits), management HSE involvement and enforcement (e.g. compliance to life saving rules) have 

created a strong safety culture in our operations.

j) Measures to conduct effective and early intervention in the event of a blowout.

The response to a blowout is contained in our Well Control Contingency Plan (WCCP) which is a specific 

requirement of our internal well control standards. The WCCP in turn is part of the wider emergency response 

framework within Shell that addresses the overall organization response to an emergency situation. Resources 

are dedicated to these systems and drills are run frequently to test preparedness (security, medical, oil spill, and 

hurricane). This same framework is activated and tested during hurricane evacuations, thereby maintaining a 

fresh and responsive team.

The WCCP specifically addresses implementing actions at the emergency site that will ensure personnel safety, 

organizing personnel and their roles in the response, defining information requirements, establishing protocols to 

mobilize specialists and pre-selecting sources, and developing mobilization plans for personnel, material and 

services for well control procedures. The plan references individual activity checklists, a roster of equipment and 

services, initial information gathering forms, a generic description of relief well drilling, strategy and guidelines, 

intervention techniques and equipment, site safety management, exclusion zones, and re-boarding. 
As set forth in 3f of this document, Shell is currently analyzing recent advances in containment technology and 

equipment and will incorporate them as they become available. 

k) Arrangements for drilling a relief well 

The size of the Shell contracted rig fleet in the GOM from 2010-2015 ensures that there is adequate well 

equipment (e.g. casing and wellhead) available for relief wells. Rigs and personnel will also be readily available 

within Shell, diverted from their active roles elsewhere. Resources from other operators can also be leveraged 

should the need arise. Generally, relief well plans will mirror the blowout well, incorporating any learning on well 

design based on root cause analysis of the blowout. A generic relief well description is outlined in the WCCP. 

l) Assumptions and calculations used in approved or proposed OSRP 

Shell has submitted Olympus MB-001 as the new DOCD worst-case scenario to the BSEE for inclusion in our 

Regional OSRP. 

Shell has designed a response program (Regional OSRP being updated with this plan) based upon a regional 

capability of responding to a range of spill volumes, from small operational spills up to and including the WCD 

from an exploration or development well blowout. Shell‟s program is developed to fully satisfy federal oil spill 

planning regulations. The Regional OSRP presents specific information on the response program that includes a 

description of personnel and equipment mobilization, the incident management team organization, and the 

strategies and tactics used to implement effective and sustained spill containment and recovery operations.

Mississippi Canyon 807, proposed locations (MB001-MB024, formerly A thru X) will be located in a water depth of 

approximately 3,028 feet. The locations will be located 2,259 feet northwest of Shell‟s previously drilled MC807 001

wellsite. 
Minor shallow buried faulting (3 to 75 feet below the mud line) and buried landslide features (from 75 feet below the mud 

line) are identified in the vicinity of these locations. There is no other evidence of seafloor or near-surface amplitudes or 

fluid expulsion features associated with these minor shallow buried faults. 

An Industrial Waste Dump site is identified in MC 806, located west of MC 807. This dumpsite consists of drums that 

have deteriorated over time. Some of the drums had been dropped outside of the limits of the site and are identified on 

the Geologic Features Map (Map 5) of the GEMS report. Within 2,000 feet of the 24 proposed locations, there are 18 

sonar targets identified as potential barrels with a 50 foot recommended avoidance, 4 sonar targets identified as modern 

debris with 100 foot avoidance, and an additional 15 sonar targets have been identified as potential barrels in the 

additional 1000‟ buffer zone surrounding the proposed locations. 

There are several flowlines and umbilicals in the vicinity of the proposed site. Shell‟s Europa flowlines and umbilicals are 

approximately 1600 feet northeast of the proposed locations. A 500 foot avoidance zone has been placed around all 

flowlines and umbilicals. The proposed locations will not interfere with any of the existing flowlines and umbilicals in the 

area.

The stratigraphy at the sites of the proposed locations consists of approximately 590-foot thick unit of very soft pelagic 

clay drape material overlying soft to firm hemipelagic silts and clays inter-bedded with chaotic mass-transport deposits. A 

minor buried fault will be penetrated approximately 9 to 72 feet below the mud line in 11 of the proposed wellsites. The 

casing program for these locations is designed for this minor buried fault penetration. Unit 2, approximately 590 to 1231 

feet below the mud line, consists of approximately 641 feet of mud-filled over-bank deposits. Unit 3 is the Blue Unit, 

identified 1231 to 2559 feet below the mud line. Unit 3 consists of 262 feet of discontinuous, sandy channel-levee 

deposits and 1066 feet of chaotic mass-transport deposits of sand, silt and clay and stratified turbidities of interbedded 

sand, silt and clay. Unit 4 is identified 2559 to 3499 feet below the mud line, consisting of 940 feet of stratified muddominated turbidites, chaotic mass-transport deposits and discontinuous, moderate amplitude deposits. Unit 5 consists of 

1489 feet of discontinuous, mud-rich mass transport deposits, sandy slope fan channel sediments and chaotic disrupted 

turbidite deposits. 

Amplitude anomalies are identified 500’ west of the proposed locations in Unit 4 (2,259 to 3,499 feet below the mud line), 

and 570’ feet west northwest of the proposed locations in Unit 5 (3,499 to 4,988 feet below the mud line). There are no 

other anomalies or bright spots identified within 2,000’ feet of proposed locations and these locations will not penetrate 

any amplitude anomalies.

Moderate to moderate high potential for shallow water flow is identified 1,493 to 2,559 feet below the mud line and 3,499 

to 4,252 feet below the mud line. Moderate potential for shallow water flow is identified 2,967 to 3,499 feet below the 

mud line. Low potential for shallow water flow is identified from Seafloor to 1,493 feet below the mud line, 2,559 to 

2,967 feet below the mud line, and 4,252 to 4,988 feet below the mud line. The casing program for these proposed 

locations is designed to minimize flow potential.

Moderate to moderate high potential for shallow gas is identified 3,499 to 4,252 feet below the mud line. Low potential 

for shallow gas is identified from Seafloor to 3499 feet below the mud line, and 4,252 to 4,988 feet below the mud line. 

Based on a high-resolution geophysical survey, consisting of frequency enhanced 3-D seismic, Enhanced Surface 

Renderings (ESR‟s), ESR‟s with amplitudes applied, and AUV high-resolution data, Mississippi Canyon 807, Proposed 

Locations MB001 through MB024 appear suitable for the planned activity.

4013 to 6137 feet below the mud line. Low potential for shallow water flow is identified from Seafloor to 1254 feet below 

the mud line, and 2673 to 4013 feet below the mud line. The casing program is designed to minimize flow potential.

Moderate to high potential for shallow gas is identified 1650 to 2366 feet below the mud line. Low potential for shallow 

gas is identified from seafloor to 1650 feet below the mud line and 2673 to 6137 feet below the mud line. The casing 

program designed to minimize flow potential.

Based on a high-resolution geophysical survey, consisting of frequency enhanced 3-D seismic, Enhanced Surface 

Renderings, and Enhanced Surface Renderings with amplitudes applied, and side scan sonar and sub-bottom profiler, this 

location appears suitable for the planned activity.

Well SD002 (S):

Mississippi Canyon 762, Proposed Location SD002 (S) is located in a water depth of approximately 3150 feet. The 

location is located near the center of a near-surface ancient slump valley. There is no seafloor faulting in the vicinity of 

this wellsite, which is located approximately 54 feet southwest of Shell‟s previously drilled MC 806-3 wellsite.

An Industrial Waste Dump site is identified in MC 806, south of MC 762. This dumpsite consists of drums that have 

deteriorated over time. Some of the drums had been dropped outside of the limits of the site and are identified on the 

Geologic Features Map (Map 5) of the GEMS report. This location will be positioned approximately 385 feet southwest of 

the nearest seafloor debris.

The stratigraphy at the site consists of Unit 1, a 672-foot thick unit consisting of very soft pelagic clay drape material, 

underlain by soft to firm hemipelagic silts and clays, over slump and debris flow deposits, underlain by stratified 

hemipelagic silty clays inter-bedded with chaotic mass-transport deposits. Unit 2 consists of approximately 582 feet of 
mud-filled over-bank deposits. Unit 3 is the Blue Unit, identified 1254 to 2673 feet below the mud line, consisting of 396 

feet of discontinuous, sandy channel-levee deposits, 716 feet of chaotic mass-transport deposits of sand, silt and clay, 

and 307 feet of stratified turbidites of interbedded sand, silt and clay. Unit 4 is identified 2673 to 4013 feet below the 

mud line and consists of 1340 feet of stratified mud-dominated turbidites, chaotic, mass-transport deposits and 

discontinuous, moderate amplitude deposits. Unit 5 consists of 2124 feet of discontinuous, mud-rich mass-transport 

deposits, slope fan channel sediments and chaotic disrupted turbidite deposits. The Top of Salt will be penetrated beyond 

the limits of this shallow hazards investigation. The casing program is planned for salt penetration.

Amplitude anomalies or “bright spots” are identified over 200 feet north of this location. These amplitudes are identified 

between 6442 to 8192 feet below the mud line. The well path will not penetrate these amplitude anomalies. 

Moderate to high potential for shallow water flow is identified 1650 to 2366 feet below the mud line. Moderate potential 

for shallow water flow is identified 1254 to 1650 feet below the mud line, 2366 to 2673 feet below the mud line, and 

4013 to 6137 feet below the mud line. Low potential for shallow water flow is identified from Seafloor to 1254 feet below 

the mud line, and 2673 to 4013 feet below the mud line. The casing program is designed to minimize flow potential.

Moderate to high potential for shallow gas is identified 1650 to 2366 feet below the mud line. Low potential for shallow

SECTION 4: HYDROGEN SULFIDE (H2S)

Based on CFR 550.245, Shell requests that the Regional Supervisor, Field Operations, determine the zones in the 

proposed drilling operations in this plan are classified as an area where the absence of H2S has been confirmed.

SECTION 5: MINERALS RESOURCE CONSERVATION

A. Technology and reservoir engineering practices and procedures 

The Mars B waterflood program is a secondary recovery program designed to maintain or slightly increase reservoir 

pressure during production in fours reservoirs in the Mars field. First injection from the Olympus TLP is scheduled to start

2021 and will consist of six down-dip direct vertical access water injectors and will compliment the current Mars A 

waterflood program.

B. Technology and recovery practices and procedures 

Injection is being optimized through targeting and positioning considerations such as location of the OWC, Kh at injection 

locations, and vertical and lateral distances from producers. Pressure maintenance will prevent the development of a 

secondary gas cap, and increase the effectiveness of the water drive mechanism. 

C. Reservoir Development 

The Mars field encompasses six OCS Leases in the Mississippi Canyon Area that are captured within the Mars Operating 

Unit. The field was discovered in 1989 and production commenced in 1996 from the Mars A TLP. Water injection from 

the Mars A TLP started in 2004 with injection into 3 primary reservoirs. Injection is planned for two other reservoirs to 

maximize production from the field.

Mississippi Canyon 807 Olympus TLP Pre-Drill Wellsites

Mississippi Canyon 807, Proposed Locations MB001 through MB024 will be located in a water depth of approximately 

3,028 feet. Minor shallow buried faulting (3 to 75 feet below the mud line) and buried landslide features (from 75 feet 

below the mud line) are identified in the vicinity of the proposed location. There is no other evidence of seafloor or nearsurface amplitudes or fluid expulsion features associated with these minor, shallow buried faults. These locations will not 

disturb any high-density areas of benthic communities.

The surface location for Shell’s previously drilled MC 807 #1 wellsite will be positioned 2259 southeast of Shell’s 

Mississippi Canyon 807 proposed locations. The surface location for Shell’s previously drilled MC 806 #2 wellsite will be 

positioned 2,827’ north and these wellsites will be within the additional 1,000’ buffer around the 2,000’ wellsite clearance. 

There are no other locations within the 2,000 foot site clearance or 1,000 foot buffer zone. Avoidance zones (500’) for 

Shell’s previously drilled MC 806 No. 1, 807 No. 2, 807 No. 3 and 807 No. 5 wellsites will be located within the 1,000’ 

buffer zone. These new wells will be positioned 6,302 feet south of Shell’s previously drilled MC 807 Mars TLP platform. 

The proposed locations will not interfere with any previously drilled wellsites.

An Industrial Waste Dump site is identified in MC 805, west of MC 807. This dumpsite consists of drums that have 

deteriorated over time. Some of the drums had been dropped outside of the limits of the site and are identified on the 

Geologic Features Map (Map 5) of the GEMS report. Within 2,000 feet of the 24 proposed locations, there are 18 sonar 

targets identified as potential barrels with a 50 foot recommended avoidance, 4 sonar targets identified as modern debris 

with 100 foot avoidance, and an additional 15 sonar targets have been identified as potential barrels in the additional 

1000‟ buffer zone surrounding proposed locations.
