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. Hydrates and Shallow gas A. Gas Hydrates are expected at V-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. fil. Lost CirculationlBreathing A. Lost circulation is not expected at fault #1. This fault has been penetrated by most wells drilled from V Pad. B. Breathing is not expected on this well. IV. Kick Tolerance/Integrity Testing A. The 10-3/4" casing will be cemented to surface. B. The 10-3/4" casing test pressure is 3500 psi. C. The Kick Tolerance for the surface casing is 130 bbls with 9.1 ppg mud,. 12 ppg LOT, and an 8.7 ppg pore pressure.

The 7-5/8" intermediate casing will be cemented with 15.8 Ib/gai tail cement to 1492' MD above the Ma sand ~ 4388' MD. F. The 7-5/8" casing test pressure is 3500 psi. G. The Kick Tolerance for the intermediate casing is infinite (at OBc, OBd, OBb, OBa, and OA) with 9.3 ppg mud, 11.5 ppg FIT, and an 8.3-8.7 ppg pore pressure. H. 6-3/4" Open hole Integrity Testing (at OBc, OBd, OBb, OBa, and OA) -FIT to a minimum of 11.5 ppg EMW 20' from the shoe. V. Hydrogen Sulfide V 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 10 ppm is measured regularly at V pad as a result of the use of ivishak gas lift gas. All V Pad gas lift wells will likely have H2S in this concentration. Note that al{ 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: Adjacent producers at TD: V-101 10 ppm V-102 25 ppm V-108 20 ppm VI. Faults A. One fault is expected to be crossed at V-203.

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 function pressure tested before the next weilbore 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: "ifi BOP sealing 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(g) 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 well control; _ _~_____ - - - - - - - - - - - - - - - - E 5.172 I 1 I I 15'00'00" GRIP7-~ I I ~ PLAN-"~'Z - I i I f I I ^ Y-118 ^ V-115 I I ^ V-03 ^ V-2131 I I ^ V-110 ^ V-100 I ^ V-111 I ^ V-103 ^ V-117 ~ ~ ^ V-106 ^ SLOT S-R I I I ^ v-1o5i ^ v-o1 I I ^ SLOT N-M I I I I I I °n ^ V-102 ^ V-SPARE (AOT s-~) I I ^ ^ V-201 I ^ V-107 ^ SLOT S-J Iz ^ V-02 0l I V-104i ^ V-204 ~ I I V-2101 ^ V-114 ~ I V-202 ^ V-119 z I V-SPARE (SLOT N-E> ^ V-109 I I V-101 I I V-211i ^ V-113 I I V-108 I I V-203 I i I I I I I I ~ I ~ s I V-PAD 1 SO SPINE ROAD = / jOwOA`IPPO I _-_ __ ice/ ~/ ~~'_'' NOTES 1.
