# A PLAN CONTENTS

(a) Plan Information Form
Under this Supplemental Exploration Plan, Anadarko Pe troleum Corporation (Anadark o) proposes to drill and complete ten wells total in Green Canyon Blocks 859 & 903: GC903 "D" & “DD”, and GC 859 "F, G, H, FF, GG, HH, I, II". The waste discharges and air emissions a ssociated with drilling to TD and conducting completion operations for these ten wells are included in this plan.
Anadarko will also conduct top-hole drilling on two additional wells with surf ace locations in Green Canyon Block 903 (EP locations GC 859 “J” and GC 903 “E”). Only waste discharges and air emissi ons associated with the tophole drilling of GC 859 J" and GC 903 "E" have been included in this plan. Drilling the top-hole sections for both wells will take approximately 20 days total.
Waste discharges and air emissions associated with drilling the two wells, GC 859 “J” and GC 903 “E”, to the final total depth (TD), as well as completion operations will be ad dressed under a future exploration plan. The remaining drilling operations to TD and completion operations will be conducted with a different ri g, which will be discussed in the subsequent EP submittal.
The wells will be drilled using either a Dynamically Pos itioned (DP) Drillship or DP Semisubmersible drilling rig. Drilling and completion operations for the proposed well locations will utilize a Subsea BOP stack. OCS Plan Information Form MMS-137 is enclosed as Attachment A-1.
(b) Location

Enclosed as Attachment A-2 is a well location plat at a scale of 1 inch = 2000 feet that de picts the surface location and water depth of the proposed well.
(c) Safety and Pollution Prevention Features
Safety features on the drilling unit will include well cont rol, pollution prevention, sa fe welding procedures, and blowout prevention equipment as described in Title 30 CFR Part 250, Subparts C, D, E, G and O; and as further clarified by BOEM Notices to Lessees, and applicable re gulations of the Environmental Protection Agency and the U.S. Coast Guard. The appropriate life ra fts, life jackets, ring buoys, etc., as prescribed by the U.S. Coast Guard, will be maintained on the facility at all times.
(d) Storage Tanks and Production Vessels


### The Green Canyon Blocks 859 & 903 wells will be drilled with a DP drillship DP semisubmersible unit.

## (e) Pollution Prevention Measures
The drilling rig utilized for these operations will comply with all applicable regula tions regarding pollution prevention and control. The rig ha s a Shipboard Oil Pollution Emergency Plan (SOPEP), which is reviewed and approved annually by the American Bureau of Shipping (ABS). The SOPEP is provided to assist employees in dea ling with an unexpected discharge of oil. Its primary purpose is to set in motion the necessary actions to stop or minimize the discharge of oil and to mitigate its effects. Effective planning en sures that the necessary actions are taken in a structured, logicalm and timely manner.
Pollution prevention measures includ e installation of curbs, gutters, drip pans, and drains on deck areas to collect all contaminants and debris. Most deck drains and some of the joints at the edge of the rig floor go overboard or into the moon pool, respectively. To prevent ocean discharge from the drains there is a dedicated drip pan un der the rotary table. The pipe racks, mud pump room, sack store, and drill floor drains go to a holding tank, which is se rved by a dedicated oily water separator. The well test area, engine room , and other major machinery spaces drains all go to slops tanks, which are served by a large general-serv ice, oily water separa tor. The containment devices are temporary. They are not meant for perm anent storage of waste. On the rare occasion that they contain wastes, they are pumped, moppe d, or cleaned within a short period of time. The chances of damage to a containment structur e during such time as it contains wastes are exceedingly small.
(f) Additional Pollution Prevention Measures
No additional measures are proposed under this plan. The activities proposed in this plan are not located offshore Florida.
(g) Description of Previously Approved Lease Activities
Anadarko has previously approved well locations in Green Canyon Blocks 859 & 903. Approval was granted to drill and complete the follo wing well locations in Green Canyon Bloc 859 under the Initial Exploration (Plan Contro l No. N-9167) approved April 23, 2008:

## B GENERAL INFORMATION
(a) Applications and Permits
Prior to beginning exploration operations the follo wing application(s) will be submitted for approval:
Application/Permit Issuing Agency Status Permits to Drill BSEE Bureau of Safety and Environmental Enforcement (BSEE) To be submitted

(b) Drilling Fluids
Type of Drilling Fluid Estimated Volume Per Well Water-based (NaCl saturated, seawater, freshwater, barite) for Pump and Dump 21,000 bbls per well**
Synthetic-based (internal olefin, ester) 13,000 bbls per well Oil-based NA

* *The actual volume ordered out will be an estimated 21,000 bbls/well of mud. Once on location this volume will be cut back and mixed with seawater to different desired mud weights which will increase the volume that is discharged at the seafloor. The estimated volume that will be discharged at the seafloor will be approximately 74,000 bbls/well (NOTE: there will be twelve wells for a total of 888,000 bbls).


### (c) New or Unusual Technology
Anadarko does not propose to use any new or unusual tec hnology to drill the well proposed in this plan.
(d) Bonding Statement
The bond requirements for the activities and facilities pr oposed in this EP are satisfied by an area-wide bond furnished and maintained according to 30 CFR pa rt 256, subpart I; NTL No. 2000-G16, “Guidelines for General Lease Surety Bonds,” and National N TL No. 2008-N07, “Supplemental Bond Procedures”.
(e) Oil Spill Financial Responsibility (OSFR)
Anadarko Petroleum Corporation (Company Number 00981) has demonstrated oil spill financial responsibility for the facilities proposed in this EP according to 30 CFR Part 253, and NTL No. 2008- N05, “Guidelines for Oil Spill Financia l Responsibility for Covered Facilities”.
(f) Deepwater Well Control Statement
Anadarko Petroleum Corporation (Company Number 0098 1) has the financial capability to drill a relief well and conduct other emergency well control operations if required.
(g) Blowout Scenario
Anadarko prepared this blowout scenario pursuant to guidance provided in NTL No. 2010-N06. The Green Canyon 859 #3 well (EP Location “J”) is addressed in this blowout scenario since it is the location with the highest potential worst case discharge (WCD ) rate for Green Canyon Blocks 859 & 903. A similar approach would be taken in the event of a blowout for the other wells located in Green Canyon

### Blocks 859 & 903. Based on NTL No. 2010-N06 guidance, the maximum hydrocarbon discharge for Green Canyon Blocks 859 & 903 is calculated to be 

## 263,660 BOPD.
Purpose This information provides a generic blowout scenario , additional information regarding any potential oil spill, the measures Anadarko Petroleum will take to prevent a blowout, and if necessary, promptly respond to manage a blowout scenario if one occurs . The following information is pursuant with 30 CFR 250.213(g), 250.219, 250.250 and NTL No. 2010-N06.
Background This section has been developed to document the a dditional information requirements for Exploration Plans as requested by NTL No. 2010-N0 6. GC 859 #3 will be approximately 3,620 ft south of the existing BHL of GC 859 #1 and approximately 3,900 ft north -northwest of the existing BHL of GC 903 #3
Information Requirements

Blowout Scenario The GC 903 #5 well will be drilled to objective sands , as outlined in the Geological and Geophysical Information section of this Plan, utilizing a MODU ri g with a marine riser and sub-sea BOP. A typical sub-sea wellhead system, conductor, and surface a nd intermediate casing program will be used.
The Blowout Scenario assumes a hydrocarbon influx o ccurs from the objective intervals, followed by a well control event. The sub-sea BOP and marine riser fails, and a blowout occurs at the seabed. The WCD scenario assumes a 13-5/8” x 14” casing string set, 11-7/8” liner set, and 10-5/ 8” x 12-1/4” open hole drilled as per the attached wellbore schematic (A ttachment H-7). The sand objectives are the WCD scenario.

Estimated Flow Rate of the Potential Blowout Category EP Type of Activity Drilling Facility Location (area/block) GC Block 859 Facility Designation MODU Distance to Nearest Shoreline (miles) 135 miles Uncontrolled Blowout (volume per day) 263,660 bbl Type of Fluid(s) Crude Oil

a) Potential for the well to bridge over: Mechanical collapse of the reservoirs in the open- hole section of the wellbore was not considered.

b) Measures to enhance the ability to conduct eff ective and early intervention in the event of a blowout:
The likelihood of surface interven tion to stop a blowout is high and is based on the following equipment specific to the MODU that has been contracted to do this drilling program:
ROV Secondary BOP Control System: The BOP is confirmed to have a ROV Intervention Panel and circuits that have the following attributes:

### Hot stab is capable of closing one set of: Blind-Shear Rams (one set) Pipe Rams (one set) Unlatch the Lower Marine Riser Package ROV hot stab to be function tested in conjunction with the Stump test and tested at the same rate and pressure as the pump installed on the ROV used by the rig. BOP panels also can be operated by an ROV from an independent supply boat in the event of a loss-of-rig scenario. Deadman/Autoshear Function: The rig is equipped with an automated sequence that closes the blind shear rams in the event of any of the following scenarios:
Inadvertent disconnect of the LMRP Loss of both hydraulic pressure and electrical supply from the surface BOP control system No human interface is required once these systems are armed.

c) Availability of a rig to drill a relief well: Per the preliminary Mutual Aid agreements that have been worked between E&P Operators in the Gulf of Mexico, Anadarko will select from the best rig option available in the Gulf of Mexico fleet if and when it is required for relief well work. As of August 1, 2013, there were over 12 additional rigs capable of operating under these conditions in the Gulf of Mexico. A rig that could be used to drill a relief well is the Transocean Discoverer Clear Leader , which is a drill ship capable of drilling in 12,000 ft of water without any constraints. The rig is currently under contract to Chevron and is on location in KC 829.
There are no nearby platforms from which to drill a relief well.

It is not feasible to drill a relief well from land.
d) Rig constraints:
A rig capable of drilling in 6,000 ft of water wi th a 15k Stack is required for any relief well operations. The Transocean Discoverer Clear Leader drill ship meets these requirements.
e) Time taken to mobilize a rig and drill a relief well:
An estimated 7-21 days is required to suspe nd operations on a deepwater GOM well and begin drilling the relief well. This assumes 0-14 days to su spend current operations on an existing well and 7 days to mobilize and be ready to spud the relief well. The estimated time to drill the relief well is 100 days which includes 20 days for additional directional work, for a total estimated time of 107-121 days from time of blowout to finishing the relief well. The drilling days were based on the proposed days to drill the GC 859 #3 well through the objec tive sand (interval of WCD) with additional time added for ranging.
The time estimate provided for the plan well is inclusive of 'both' drilling 'and' completion operations. As a completion is not typically part of relie f well operations no time has been included for completion operations in the relief well estimate. Therefore the estimated time for a relief well should be less than for the plan well. In additi on, information and learning from the drilling of the

### original well may provide opportunities to optimi ze drilling performance for relief well operations and thus reduce the required drilling time.

f) Assumptions and calculations used in approved or proposed Oil Spill Response Plan:

 The Merlin reservoir simulator, Avalon nodal an alysis, and Prosper nodal analysis programs were used to estimate the WCD for this well. Supporting input data can be found on Data Sheets 1 through 3 (Attachments H-1 through H-3), and Merlin and Avalon-formatted Prosper nodal files are included as Electronic Attachments 1 and 2. At the seafloor, the estimated worst case discharge for the we ll is 263,660 BOPD based on flow from the objective sands.

 The maximum total volume during a bl owout could potentially be 31,902,860 bbl assuming 121 days for the maximum duration of a blowout, multiplied by the worst case daily uncontrolled blowout volume of 263,660 bbl.

g) Measures taken to reduce the likelihood of a blowout:

 Well Design : Anadarko utilizes a systematic well design process for the planning and construction of a well operation. This process taps into the vast depth of experience Anadarko possesses in the Deep Water drilling arena and involves a multi-team peer review of the well design, shallow hazards, and formation pressure ha zards expected during drilling. This process minimizes the potential for an unplanned well control event that could lead to a blowout. This process will also include a Registered Professional Engineer review and approval of the final casing design and cementing program.
A detailed pre-drill assessment of formation pr essure provided by Anadarko’s Geological and Geophysical team, along with third- party consultants, allows for a mud program that provides an overbalanced mud weight for the safe drilling of the well. For an exploration well, this may also include taking formation pressures to confirm the actual formation pressure during the well construction process to minimize the risk of an unplanned well control event. The pore pressure environment is understood due to the nearby offset wells.
The well construction process also requires a systematic review and management acceptance of the start-up preparation work for the rig and crews and the third-party technical audit work on the rig and the rig’s well control equipment. This measures the rig’s ability to handle an unplanned well control event and provide assurance that the rig can successfully mitigate a loss of well control event and prevent it from becoming a blowout scenario.

 Barrier Philosophy : For all well designs, Anadarko requires and uses a redundant barrier philosophy, that being two independent tested barriers, including one mechanical barrier, across each flow path during well operations. For the final casing string (or liner if it is the fina l string), there shall be two mechanical barriers in addition to cement inside the wellbore.
It is also standard practice to conduct pressure testing, in accordance with the law, to confirm integrity on all relevant barriers.
In addition, all intermediate a nd production casings returned to th e wellhead will be locked down.

###  BOP and Well Control Equipment : The rig will have an 18-3/4” 15k psi BOP with primary and secondary BOP control systems. The BOP will ha ve been completely recertified compliant to OEM specifications by a qualified third-party. Prior to commencement of operations, independent third-party verification will be obtained that the sub-sea BOP is designed for the specific equipment on the rig and this specific well design. 250.416(f)

 BOP and Well Control Equipment Testing : To ensure effectiveness of the BOP and well control equipment, a testing program will be c onducted prior to running the BOP and then during the well operations. This testing pr ogram will provide compliance w ith current federal regulations for pressure and function testi ng and will also provide periodic assurance on the performance of both primary and secondary BOP control systems including actual interface operations with the ROV and the ROV panel.

 Well Control Training and Drills : Anadarko requires that key nominated onshore and offshore positions, including rig contractor personnel, hold a WellCAP or equivalent well control training certificate, renewable every two years for the type of floating drilling operation being conducted. Anadarko also monitors compliance for its personne l with the federal regulations and Sub-Part O for well control training. A comprehensive program of well control drills w ill be conducted offshore to ensure readiness to identify and then manage a well control situation and thereby minimize the potential for a well control event to lead to a blowout scenario.
h) Arrangements for drilling a relief well:

• Anadarko maintains a master agreement with W ild Well Control, Inc. for advice, management, engineering, well kick pre- and post-modeling, and resource support for an unplanned loss-of-well-control event. If any well control event occu rs, Wild Well Control, Inc. would be contacted and mobilized if required to support Anadarko’s operational team, both in the onshore and offshore locations.
•The conceptual relief well design is similar to the design of the GC 903 #5 well, in that, casing weights, grades, and setting points would be identical. A mu ltiple block shallow haza rd assessment has been completed (and submitted) for the area around GC Blocks 903 and 859. Site clearance letters for surface locations in both blocks have been completed and de emed acceptable for drilling. The potential areas for high density chemo-synthetic communities in the study area have been identified and can be avoided. Depending on the nature of the blowout scenario, well geometry, and total depth required to intersect the blowout, previously submitted surface locations and/ or additional surface locations would be submitted and all reviewed for best suitability for the locati on of the relief well if needed. The conceptual well design is not anticipated to take over 2 days to finalize upon initialization.
•Anadarko’s philosophy is to carry adequate inventory in stock to drill a complete well(s) from surface to TD. Back-up long-lead equipment equivalent to the orig inal well design will be carried in stock to allow a rapid response. This includes a spare deepwater sub-sea wellhead system and the large OD casing (36”, 28”, 22”, 18”, and 16”) and connect ors required. Smaller OD casing (14”, 11 7/8”, and 9 7/8”) is considered widely available on the ground in the GOM and would be resourced out of existing inventory or from suppliers as required.
•Existing service agreements will be in place for support services, including drilling fluids, casing running, cementing, ROVs, solids control, mud logging, directional drilling, LWD/MWD, logging, boats, and helicopters.

### •Specialist services for range finding to drill the relief well in close proximity to the original wellbore at the reservoir depth will be provided through Vect or Magnetics LLC. Sperry Drilling/Halliburton and Schlumberger have in-house pe rsonnel to supplement Vector Magnetics LLC under our existing directional drilling agreements.
