Proposed Wellsite MC692-C 

Block 692 (OCS-G-34455) 

Mississippi Canyon Area 

Gulf of Mexico 

Murphy Exploration & Production Co. (Murphy) contracted Geoscience Earth & Marine Services Inc.®, 

(GEMS) to provide an assessment of the shallow geologic conditions to determine the favorability of 

drilling operations for the proposed location MC692-C in block 692 (OCS-G-34455), Mississippi Canyon 

Area, Gulf of Mexico. This letter addresses specific seafloor and subsurface geologic conditions, to a 

depth of about 4,893 ft below the mudline (bml), at the Proposed Wellsite MC692-C. The proposed 

location appears suitable for exploration drilling operations; however, caution is recommended while 

drilling through the sand-prone sequences below 394 ft bml with respect to the potential for shallow water 

flow and shallow gas. 

The following sections provide details specific to the well location, including: available data, Notice to 

Lessees (NTL) requirements, man-made features, and wellsite conditions. 

Proposed Well Location

The surface location for Proposed Wellsite MC692-C is in the north-central portion of MC 692. Murphy 

plans to drill this well using a dynamically positioned drilling vessel. Our assessment addresses the

seafloor conditions within a 2,000 ft radius around the proposed wellsite location. Murphy provided the 

following coordinates for the proposed wellsite:

Available Data 

The following discussion is based on findings provided within the main body of the geohazard and 

archaeological report for Block MC 692 (OCS-G-34455), GEMS Report No. 1012-2152b (GEMS, 2012). 

The text, maps, and figures included in the report provide detail on the regional geology of the survey 

area. Data assessed for the report and site clearance letters include a 3-D time volume and AUV 

(Autonomous Underwater Vehicle) data. 

The 3-D seismic time volume provided by Murphy for the geohazard analysis, covers a 25 square-mile 

area that includes all and portions of Federal lease Blocks 647-649, 691-693, and 735-737 in the

Mississippi Canyon (MC) protraction area (Figure C-1). Additionally, an AUV survey was conducted in 

October 2012 by C & C Technologies, Inc. (C & C) over the blocks of interest (Figure A-1). GEMS used 

the C & C survey data, to complete an archaeological and geohazard assessment over MC 692 

(GEMS, 2012). A scanned copy of the gamma ray and resistivity logs in addition to the scout ticket for 

Murphy’s MC 737 #1 well were provided to GEMS by Murphy. The well logs were used to identify 

potential sand layers within the stratigraphic units in the survey area.

NTL Requirements

The following letter complies with the Bureau of Ocean Energy Management (BOEM) Notice to Lessees 

(NTL’s) 2008-G04, 2008-G05, and 2009-G40, (MMS, 2008a, b, and 2010). The Federal lease Block 

MC 692 is located within a historically significant area (BOEM, 2011); therefore, requirements set forth in 

NTL 2005-G07 are applicable (MMS, 2005). An archaeological assessment was completed for MC 692 

and included as Appendix A in the main report (GEMS, 2012). The anticipated archaeological conditions

within 2,000 ft of the proposed well are included in the Man-Made Features and Archaeological 

Assessment section of this letter. 

According to NTL 2008-G05 (MMS, 2008b), 3-D seismic reflection data may be used for shallow hazard 

assessments with approval from the BOEM, Gulf of Mexico Region. A power spectrum analysis was 

conducted from the 3-D seismic data cube provided by Murphy to illustrate the data parameters 

(Figure C-2). The power spectrum curve was generated within a 500-ft radius of the intersection of the 

inline and crossline at the proposed wellsite. We converted the amplitude vs. frequency spectrum, 

generated by the SMT software, to power vs. frequency by squaring the amplitude values as described by

J. A. Coffeen, 1978. 

Figure C-2. Power Spectrum Analysis Curve, Proposed Wellsite MC692-C

Man-Made Features and Archaeological Assessment

The surface location is clear of any wells, pipelines, or platforms within a 2,000 ft radius from the 

proposed wellsite. The closest existing infrastructure to the proposed well is a 14 to 16-inch gas pipeline 

owned by WFS and a 14 to 16-inch oil pipeline owned by Williams. These pipelines are about 5,200 ft 

northwest of the proposed location (Map No. MC692C-1). Based on the available data, no archaeological

avoidances and no known shipwrecks or objects exist within the area of potential effect for the proposed 

Well MC692-C. There are no unidentified side-scan sonar contacts located within 2,000 feet of the 

proposed MC692-C well (Map No. MC692C-2). Unidentified Sonar Contact No. 2 is located about 

3,400 ft west of the proposed wellsite. The sonar contact measures 6.80 ft in length, 2.58 ft in width, and

2.07 ft in height. The contact is considered to be modern debris from shipping, storms, fishing, and/or 

exploration activities. An archaeological avoidance is not assigned for this contact; however, a 100-foot 

geohazard avoidance is recommended for all side-scan sonar contacts. Unidentified Side-Scan Sonar 

Contact No. 8, located in the east-central portion of MC 692, is interpreted as a potential shipwreck. A 

1,500-foot archaeological avoidance for this contact is recommended. Side-Scan Sonar Contact No. 8 

lies about 1.3 miles southeast of Proposed Well MC692-C. 

Wellsite Conditions 

The proposed location is clear of any constraining geologic conditions along the seafloor within a 2,000 ft 

radius of the proposed wellsite. The shallow stratigraphy at the proposed well location reflects alternating 

deposition of mass-transport, turbidity flow, and slope-fan deposits interbedded with hemipelagic clays. 

Overpressured sands and minor amounts of shallow gas are possible within the sand-prone sequences. 

Precautions should be made when drilling through these potentially overpressured intervals. 

Water Depth and Seafloor Conditions

Seafloor conditions are favorable at the proposed wellsite location. The water depth at the proposed 

surface location is approximately -5,917 ft and the seafloor slopes southeast at about 0.2° 

(Map No.MC692C-1). The proposed well location lies along a subtle, gently-dipping seafloor 

(Map No. MC692C-2). Slightly irregular/hummocky seafloor conditions are evident at the proposed 

location. The hummocky morphology is the seafloor expression of underlying mass-transport deposits. A 

surficial drape (~10 ft thick) of high water content silty clays covers the seafloor (Illustration MC692C-1). 

Deepwater Benthic Communities

Deepwater benthic communities are not expected at the proposed wellsite. There are no features or 

areas that could support significant, densely-populated benthic communities within 2,000 ft of the 

proposed location. The Side-Scan Sonar Mosaic (Map No. MC692C-3) shows normal or ambient returns 

along the seabed with no indication of any hard-bottom or fluid expulsion events within 2,000 ft of the 

proposed well. 

Stratigraphy

Subbottom Profiler Line 116 is the closest AUV line to the proposed location (Illustration MC692C-1). 

Inline 1328 and Crossline 5840 are the closest 3-D lines to Proposed Wellsite MC692-C 

(Illustration MC692C-2). The Tophole Prognosis Chart (Illustration MC692C-3) shows the crossline 

annotated with calculated depths to the mapped horizons, predicted unit lithologies, and potentials for 

both shallow water flow and shallow gas. 

Stratigraphic conditions to the limit of investigation (4,893 ft bml) are shown on Illustrations MC692C-1 

through MC692C-3. The sedimentary section has been subdivided into five seismic units or sequences. 

The AUV subbottom profiler shows an acoustically transparent drape approximately 10 ft thick at the top 

of Unit 1 beneath the proposed location (Illustration MC 692C-1). The drape likely consists of very soft, 

high water content pelagic clays. Shear strengths will gradually increase corresponding to a decrease in 

water content throughout the remainder of Unit 1 (159 ft bml). 

A mass-transport deposit, about 30 ft thick, occurs just beneath Horizon 10 at the top of Unit 2 

(159 ft bml, Illustration MC 692C-1). The mass-transport deposits likely have higher than normal shear 

strengths. The remainder of Unit 2 (Horizon 10 to Horizon 20) will consist primarily of mud-rich turbidites 

interlayered with thin mass-transport deposits. The Measurement While Drilling (MWD) logs for the 

MC 737 #1 well show a sand layer less than 10 ft thick at about 364 ft bml. This sand layer may correlate 

to the base of Unit 2 at the Proposed Wellsite MC692-C. 

Units 3 and 4 are slope fan-channel complexes (Illustrations MC692C-2 and MC692C-3). These intervals 

are part of regional sequences known as the Blue and Green units. The sequences will consist of 

stratified and chaotic intervals from 394 ft to 2,719 ft bml. The stratified sediments include turbidites, 

levee, overbank, and sheet sand deposits. Chaotic intervals include mass-transport deposits and

channel fill. Thin, continuous sand layers and seams are likely within the stratified intervals interbedded 

with clays and silty clays. The chaotic intervals will contain mud-rich sediments; however, scattered sand 

pockets and layers are likely. The MWD logs for MC 737 #1 display sand layers throughout the Blue and

Green units. Sand layers measuring up to 10 ft thick within the Blue unit and up to 40 ft thick within the 

Green unit are evident at the MC 737 #1 well. Sediments within the Blue unit at the MC 737 #1 well 

consist of stratified turbidites while Blue unit sediments at the proposed location are predominantly 

clay-rich, mass-transport deposits. Potential sand seams within the stratified slope-fan deposits at the 

MC 737 #1 well may not correlate to the chaotic mass-transport deposits at the proposed location within 

Unit 3 (Illustration MC692C-4). Various sand layers within the Green unit at the MC 737 #1 well could not 

be directly correlated to the proposed wellsite; however, thin sand seams are expected within the Green 

unit slope-fan deposits at the Proposed Wellsite MC692-C (Illustration MC692C-4). 

Unit 5 (2,719 ft to 4,893 ft bml) consists of stratified reflectors to the limit of the investigation. The section 

will consist of turbidites interbedded with thin mass-transport deposits. The turbidites will be alternating 

layers of clay, silt, and sand. The MWD logs show interspersed sand layers up to 70 ft thick at the 

MC 737 #1 well. Similar stratigraphy is expected at the Proposed Wellsite MC692-C between 2,719 ft 

and 4,893 ft bml (Illustrations MC692C-3 and MC692C-4). 

Faults 

Proposed Wellsite MC692-C is not expected to intersect any seafloor faults (Map No. MC692C-4 and 

Illustration MC692C-2). The closest seafloor fault lies approximately 3,900 ft southeast of the proposed 

location. This fault trends northeast to southwest and is downthrown to the southeast. 

A vertical borehole will intersect a buried fault at about 4,783 ft bml (Illustration MC692C-3). The fault 

trends northeast to southwest and is downthrown to the northwest. This fault will not be a constraint to 

drilling operations. 

Other buried adjustment faults exist near the proposed wellsite within Unit 5 (2,719 ft to 4,893 ft bml). 

These faults do not appear to be intersected by the proposed well and are not expected to impact drilling 

operations. 

Shallow Gas and Shallow Water Flow 

The potential for shallow gas at this well location is generally negligible to low, while the potential for 

shallow water flow is negligible to moderate (Illustration MC692C-3). 

Shallow Gas. There are no apparent subsurface high-amplitude anomalies directly beneath the 

proposed wellsite (Map No. MC692C-4 and Illustration MC692C-3). A negligible potential for 

encountering shallow gas exists within the clay-prone intervals within Units 1 and 2 (seafloor to 

394 ft bml). There is a low potential for encountering shallow gas within Unit 3 (394 ft to 749 ft bml), 

Unit 4 (749 ft to 2,719), and Unit 5 (2,719 ft to 4,893 ft bml). Low- to moderate-amplitude reflectors within 

the channel, turbidite, mass-transport, and slope-fan deposits may indicate gas-filled, coarse grained

sediments of predominantly clay-rich intervals. Minor amounts of solution gas may be encountered within 

isolated sands. 

Shallow Water Flow. The Blue and Green units (Units 3 and 4) are slope fan-complexes that contain 

sand-rich intervals and have sourced shallow water flow problems in the Mississippi Canyon region 

(BOEM, 2013b). Nine incidents are reported from wells in a 20-mile radius of the proposed MC 692-C 

location within these sequences. Reported depths below the mudline to the flows vary from 924 ft to 

2,374 ft. The severity of the flows varied from moderate to low. Exploration and production wells in MC 

736 to the south do not appear on the BOEM listing of shallow water flow incidents; however, no drilling 

reports are available from these offset wells. MWD logs for Murphy’s MC 737 #1 well were provided to 

assess potential sand layers within the stratigraphic units at the proposed well location. Based on the 

seismic character, regional history of Blue and Green units, and the MWD logs from the MC 737 #1 well,

we consider the section from 394 ft to 2,351 ft bml to have a moderate potential for overpressured sand 

layers. The MWD logs show interspersed sand layers throughout Units 3 and 4. Sand layers at the 

MC 737 #1 well measure up to 10 ft thick within Unit 3 and up to 40 ft thick within Unit 4. Although these 
Proposed Wellsite MC692-C Site Clearance Letter

Geoscience Earth & Marine Services, Inc. ® // 6 

FORUM ENERGY TECHNOLOGIES, INC. 

sand layers may not directly correlate to the sediments in Units 3 and 4 at the proposed well location, 

interbedded sand layers are expected. 

Units 2 and 5 have a low potential for overpressured sand layers. Any sands encountered within the 

turbidite and mass-transport deposits within this unit are expected to be thin seams and not likely to

produce sustained flows. The clay-rich surficial sequence (Unit 1) has a negligible potential for 

overpressured sands. 

Results and Recommendations 

The Proposed Wellsite C, Mississippi Canyon block 692, appears suitable for exploration drilling operations; 

however, some constraints were observed. We advise using caution while drilling through the potential

overpressured sands below 394 ft bml, some of which may contain minor amounts of biogenic gas. Particular 

concern should be given to Units 3 and 4 (394 ft to 749 ft bml and 1,473 ft to 2,351 ft bml) that correlate to the 

regional Blue and Green units. These units are associated with numerous water flow events throughout much 

of the Mississippi Canyon Area. 

Closing 

We appreciate the opportunity to be of service to Murphy Exploration & Production Co., and look forward 

to working with Murphy on future projects.
