The Schrader in the target fault block is expected to be normal pressured at 8.3-8.6 ppg EMW. This pressure is estimated based on offset well pressures and material balance. 11. Hydrates and Shallow gas A. Gas Hydrates are expected at L-pad from the SV5 thru the SV1 sands below the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices and precautions for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation/Breathing A. Lost circulation is not expected at fault #1. This fault has been penetrated by most wells drilled from L Pad. B. Breathing is not expected on this well. IV.

L-Pad development wells may have "kick tolerances" in the 25 bbl range. A heightened awareness of kick detection, pre-job planning and trip tank calibration will be essential while drilling/tripping the intermediate/production intervals. V. Hydrogen Sulfide L Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. No measurable H2S is being produced from the formation at this time. However 5 - 50 ppm is expected as a result of the use of Ivishak gas lift gas. All LV Pad gas lift wells will likely have H2S in this concentration. Note that all injection has been with produced water not seawater. H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: Adjacent producers at Surface: L-106 50 ppm L-102 20 ppm Adjacent producers at TD: L-201 10 ppm VI. Faults A. Two faults are expected to be crossed in L-204. No losses are expected to be associated with these faults. No faults are expected in the reservoir section, although sub seismic faults with throws <25' may be encountered.

Re uest The AOGCC is in the process of developing a guideline document clarifing the intent of the regulations pertaining to function pressure testing ram type BOP's. BPXA requests a variance to the provisions of 20 AAC 25.035 (e}(10)C regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes, except when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadvertently closed on a tool joint during routine operations.} The activities associated with this request will not compromise the integrity of the BOP equipment. Background AOGCC regulations require rams that have been used in the course of primary drilling & completion, workover and through tubing drilling operations be #unction pressure tested before the next wellbore entry. This is not a new regulation. The intent of this regulation is to ensure that ram type equipment has integrity after it has been utilized in a wellbore...for example; to ensure integrity if a ram was closed on a tool joint. The exact regulation language is: "if BOP sea{ing ram type equipment has been used, it must be function pressure-tested, before the next wellbore entry, to the required working pressure specified in the approved Permit to Drill, using anon-compressible fluid, except that an annular type preventer need not be tested to more than 50 percent of its rated working pressure;" The pertinent sections are: 20 AAC 25.035 (e)(10)C PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036 (d}(4} THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285 {f)(2) TUBING WORKOVERS: 20 AAC 25.286(e)(1) WORKSTRING SERVICE OPERATIONS This issue has been discussed with Winton Aubert at the AOGCC. The test requirement in the regulation is intended to apply to ram type equipment only. The AOGCC understands that ram type BOP's are utilized for purposes other than well control in the normal coarse of operations. The regulations allowing a variance are at 20 AAC 25.035(h) PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036(f) THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285(h) TUBING WORKOVERS; 20 AAC 25.286(8) WORKSTRING SERVICE OPERATIONS...which says generally: 20 AAC 25.035(h)... Upon request of the operator, the commission will, in its discretion, approve a variance (1) from the BOPE requirements in (e) of this section if the variance provides at least an equally effective means of welt control; L-204, L1, L2, L3, & L4 PROPOSED COMPLETION Phoenix Pressure Gauge with control lines to surface RA Tag TBD 20" X 34" 215.5 Ib/ft, A53 ERW Insulated @ 109' Halliburton X-Nipple (3.813" ID) @ 2200' TVD 4-112", 12.6 Ib/ft, L-80, BTC-M Coupling OD: 5.2" Drift/ID : 3.833"/3.958" 10-3/4", 45.5# K-55 BTC Csg @ 3,449' MD TREE: FMC 4-1/16" 5M WELLHEAD: FMC Gen 5 System 11", 5M csg.head w/ 7" mandrel hanger 8 packoff 11" x 11", 5M, tbg spool w/ 11" x 4-1/2" tubing hanger with control line ports 11" X 4-1/16" Adaptor Flange Orig KB elev (N-9ES) _ ' 4.5" Baker sliding sleeve with 3.813" ID @ GLM Design: 7-518" X 5-1l2" Baker PRM Packer @ #4 -TBD' TVD - 4-1/2" X 1" KBG-2 - SV #3 -TBD' TVD - 4-1/2" X 1" KBG-2 - DV Halliburton X-Nipples (3.813" ID) #2 - 4 jts above sliding sleeve - 4-1/2" X 1" KBG-2 - DV - 4.5" WLEG @ 5,800' MD #1 - 2 jts above sliding sleeve - 4-1/2" X 1" KBG-2 - DV Versapro SFMOBM in each Lateral and in mother bore from tbg tail down.
