Condition of Cellar The cellar/containment area around the well had water in it due to a drain that was present. It was and had been raining i and the drain from the level above drains here. Small old signs of hydrocarbons on some of the area surrounding the well that is typical. None of the signs appeared to be recent. Surrounding Surface Condition The area surrounding the well was well kept.

Other Notes: • There has been no change in Well An -52's mechanical condition, based on monitored pressure trends. The well was suspended in good mechanical condition in July, 1995, with a cement retainer and cement on top of the retainer isolating the casing damage and completion interval below. • Formation pressure from surface to the top of the completion interval is a normal pressure gradient. The Tyonek C Sand completion interval is subnormally pressured due to offset well production. • The proposed plan for Well An -52 is to maintain its suspended status and continue monitoring the well until Anna Platform production is shut -in and an overall platform abandonment plan begins execution.

I had been on standby for this test for the previous 24 hours during which Evan Harness (Unocal Drilling kept me well informed of the rigs progress. I was called out at approximately 0400 hrs this morning and arrived the platform at 0515 hrs. The rig was ready to test when ! arrived. I made a cursory tour of the rig. The test once started went very well with all components functioning properly and holding its pressure test. The test lasted 2.5 hours and could have been shorter if not for a test'plug leak due to the annular preventer dragging it of seat during its operation. The Accumulator test showed it to be in very good shape with a total recharge time of 1minute 18 seconds (avg. 2:45). As was the case during the last test, the equipment and rig crew performed exceptionally well and is indicative of the commitment by Unocal and Pool to provide support for making the safest and best drilling enviroment. The overall condition of the platform and rig was in outstanding shape. Summary: i witnessed the weekly BOP test Unocals Anna platform platform. Test time two and one half hours. No failures.

Notice of Public Hearing STATE OF ALASKA Alaska Oil and Gas Conservation Commission Re: The application of Union Oil Company of California (Unocal) for exception to 20 AAC 25.055 to allow drilling the Granite Point State 18742 No. 52 development oil well. Unocal by letter dated October 17, 1994 has requested an exception to the provisions of 20 AAC 25.055(a)(3) for the drilling of a development oil well to the Middle Kenai oil pool in the Granite Point Field located in the Cook Inlet Basin, Southcentral Alaska. The exception would allow Unocal to directionally drill the Granite Point State 18742 No. 52 development oil well to a producing location that is closer than 500 feet from a lease line which delineates a change in ownership. The proposed surface location is 730' from the north line and 682' from the east line of Section 12, T10N, R12W, Seward Meridian' (SM)'and the proposed bottom- hole location is 1995' from the south line and 459' from the west line of Section 12, T10N, R12W SM. A person who may be harmed if the requested order is issued may file a written protest prior to 4:00 PM January 27, 1995 with the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501, and request a hearing on the matter.

Russell A. DouglaS~ Alaska Oil and Gas Conservation Commission Published January 12, 1995 Memorandum To: Commission ~. ",~'( / /, ~ January 13, 1995 I &'~,. oJ~4 Unocal Request for Divener Waiver -- Grmte ~. ~na Wells 50,51 & 52 Fm: State of Alaska Oil and Gas Conservation Commission Unocal has requested a waiver of diverter requirements on the subject wells. They propose to drill the 30"x18 5/8 conductor hole to 1100' with a flow nipple then drill the 17 1/2"x13 3/8" surface hole to +/-4500' with a 20 3/4", 3000 psi. BOPE system. They state in their application letter that the fracture gradient anticipated at the casing shoes is .80 psi/foot and the rock will be competent enough to shut in the well and circulate a kick rather than divert. The fracture gradients are based on recent leak off tests done in the Granite Pt. Field and Cook Inlet area. A review of 4 wells which offset the subject wells showed 2 had elevated gas, Anna 35 at about 3900' and Anna 37 which had to be shut in to circulate out gas at 3800 feet. Both situations were handled without undue procedures and drilling resumed. In Anna 35, mud weight was raised from 8.9 ppg at 3700 feet to 10.2 at 3900 feet and remained in that range to 9000 feet. In Anna 37 mud weights ranged from 8.8 to 9.4 ppg from 1000 to 4900 feet and increased to 10 ppg by 9800 feet. None of the 4 wells indicated abnormal pressures or mud weights above 4500 feet. Unocal states that there is no gas above 1100' in the vicinity of the Anna platform based on the information available to them. Regulation 20 AAC 25.035 (b) (3) and (c) (2) authorizes the Commission to waive diverter requirements if drilling experience in the near vicinity indicates a diverter system is not necessary. The same approach and arguments were the basis of the diverter waiver granted on Dillon wells 16 & 17 in April, 1994. The proposal to drill the surface hole to 1100' with a drilling nipple means there is no annular preventer to divert the well and returns go straight to the shakers and pits. For the hole sections from 1100-4500', their permit application shows a 20 3/4" BOP system with a 2000 psi annular preventer and a diverter spool which will be blinded off and not used. Unocal believes the diverter is not appropriate and would rather use positive control measures and shut in on kicks where the formation is competent. In summary, a review of AOGCC well histories on four wells in the vicinity of the proposed wells indicated no shallow gas above 1100' noted on drilling summaries. Two cases of elevated gas were noted between 3700 and 3900 feet which were handled by ordinary drilling and circulating procedures. Recommendation: Absent shallow gas above 1100 feet and other notable drilling problems in the vicinity of the well to be drilled, we recommend approval of the waiver of diverter requirements. Gas kicks below 1100 feet can be shut in and circulated if fracture gradients are in the range stated. If there are other circumstances which the Commission thinks would cause a need for diverter use, Unocal should be allowed to address those circumstances.

Union Oil Company of California (Unocal) submitted an application dated January 6, 1995 requesting exception to 20 AAC 25.055(a)(3) and Rule 2 of Conservation Order No. 76 to allow drilling the Granite Point State 18742 No. 52 development oil well to a producing location in the Granite Point Middle Kenai oil pool that is closer than 500 feet to a drilling unit boundan, which delineates a change in ownership in the Granite Point Field. 2. Notice of opportunity for public hearing was published in the Anchorage Daily News on January 12, 1995 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: The Unocal Granite Point State 18742 No. 52 well as proposed ,,viii be a deviated hole drilled from a surface location 730' from the north line and 682' from the east line of Section 12, T10N, R12W, Seward Meridian (SM) to a bottom-hole location 1995' from the south line and 459' from the west line of Section 12, T10N, R12W SM. 2 Offset owner Mobil Oil Company has been duly notified. An exception to 20 AAC 25.055(a)(3) and Rule 2 of Conservation Order No. 76 is necessary to allow drilling of this well. _ CONCLUSION: Granting a spacing exception to allow drilling of the Unocal Granite Point State 18742 No. 52 well as proposed will not result in waste nor jeopardize correlative rights. Conservation Order No. February 1, 1995 Page 2 NOW, THEREFORE, IT IS ORDERED: ' Unocal's application for exception to 20 AAC 25.055 and Rule 2 of Conservation Order No. 76 for the purpose of drilling the Granite Point State 18742 No. 52 well is approved as proposed.

Surface location: 730'FNL & 682'FEL, Sec. 12,T10N,R12W, SM 2. Top of producing interval: 2532'FSL & 1578'FWL, Sec. 12,T10N,R12W,SM 3. At total depth: 1995'FSL & 459'FWL, Sec. 12, T10N,R12W,SM While the top of the Producing Interval lies more than 500 feet from a property, line, the bottomhole location falls within the 500 foot boundary. Therefore, there is the possibility that the productive interval may extend to within 500' of the property line. It is for this reason that Unocal makes this application. The affected property, line lies within ADL 18742, as shown on the required plat, attached hereto as Exhibit 1. The verification required by the regulation is attached as Exhibit 2. The owners and operators of the offsetting lease and governmental property line affected by this request have been notified as evidenced by the attached Exhibit A, pursuant to Rule 7.

Alaska 99519-0247 Telephone (907) 276-7600 UNOCAL 4 Alaska Region December 28, 1994 0 9 Mr. David Johnston Commissioner Alaska Oil & Gas Conserwation Commissioner 3001 Porcupine Drive Anchorage, AK. 99501-3192 Dear Mr. Johnston: Please find enclosed applications for Permit to Drill (Form 10-401) for the Anna Platform wells #50, 51 & 52. The timing to spud these wells is approximately mid January 1995 upon the completion of the current well Anna 3rd. As part of this continued development drilling program UNOCAL is requesting that the AOGCC waive the diverter system requirement on both the (30") structural and (18-5/8") surface casing strings for all three of these wells. This waiver request is similar to our April & July 1993 request for wells #16, 17, & 18 at the Dillon Platform which was subsequently approved by the AOGCC..~ outlined in each well procedure, UNOCAL is intending to drill out the 30" structural casing to +1100' with a flow nipple then install a 20-3/4" 3M BOPE stack on the 18-5/8" casing that will be cemented at +1100' to surface. The 18-5/8" casing will then be drilled out to a depth of :t:4500' and 13-3/8" intermediate casing will be cemented from that depth to surface. UNOCAL has selected the casing points for the 18-5/8" at +1100' and the 13-3,:8" at +4500' to be areas of competent formations. No gas bearing zones are evident above _+1100', base~ on offset well data. It is anticipated that the minimum formation fracture gradients at both shoe depths to be 0.80 psi/ft. UNOCAL's recent experience in the Middle Ground Shoals Field at the Dillon Platform and elsewhere in the Cook Inlet (see Leak OffTest Data) has demonstrated true fracture grachents ran~mng from 0.75 - 0.94 psi/ft. In all three wells at Anna the maximum surface pressure (MSP) expected while drilling below the 18-5/8" surface casing will be far less than the anticipated fracture pressures. Since the casing shoes will not break down in a well kick situation and the setting depths are in competent formations. UNOCAL believes these are prudent casing designs and warranted operations. Mr. David Johnston December 28, 1994 Page - 2 UNOCAL plans to complete Anna #50. 51 & 52 ~ith hydraulic pumping completions; these wells are expected to require artificial lffi for production of oil reserves. An outline of how UNOCAL plans to safely and economically produce these ~lls will be submitted under a separate cover. Due to the close proximity, of Anna 51 and Anna 52 to Anna 36 and Anna 33, respectively, we are requesting Administrative Approval, pu_r~mnt to Rule 7 of Conservation Order No. 76, of UNOCAL's placement of these wells closer than 1000 feet to any well drilling to or capable of producing from the same pool (Rule 2, Co. No. 76). The proposed locations of Anna~ 51 and Anna 52 are reasonably designed to further the purposes of our drilling program in the Granite Point Field, Middle Kenai Oil Pool. Additionally, due to the total depth position of Anna 52 relative to the lease line, we are pursuing an execption to Rule No. 2 of Consel-~ation Order No. 76 which will be addressed under separate cover. Due to the batch process of drilling the three aforementioned wells, it is requested that an unconditional permit to drill be granted for the Anna 50 and Anna 51, while a conditional permit to drill the Anna 52 be granted for the top hole sections, while final approval for the 8-1/2" hole section will remain reserved until the execption to Rule No. 2 Conservation Order No. 76 has been granted. This will enable UNOCAL to more economically carry on the drilling program in the Granite Point Field, Middle Kenai Oil Pool. If you should have any questions regarding these permits please contact C. Lee Lohoefer (Senior Drilling Engineer) assigned to this project. T~ank you for your attention to these matters.
