Each of these wells was found to have a void in the conductor. These voids were filled with cement(one with carbolite) and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC,this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The attached spread sheet presents the well name,top of cement depth prior to filling and volumes used on each conductor.

I was looking through some reports and ran across this well. It apparently was drilled to the Lisburne, tested and then plugged back to do a Kuparuk completion. The last item in the file inhere is the sundry to do the plug back and complete in the Kuparuk which was filed back in October 1998. Could you check the well file on this one? I am not sure the work was ever done since our production reports has no production ever recorded for the well. Thanks for the help. Tom.

The well was drilled in May 1997, and completed in the Lisburne formation with a 3 ½" liner. The plan is to plug back above the 3 1/2" liner and abandon the Lisburne formation to recomplete the well in the Kuparuk formation. The Kuparuk A4 sand will be perforated and fractured to allow recovery of Kuparuk reserves. The cement plug procedure will consist of setting an inflatable cement retainer at approximately 7900', which is about 150' above the 3 W' liner. The plug will be completed by .pumping 31 bbl of cement below the retainer to fill the wellbore, a~g,,~bbl of cement on top of the retainer. The Kuparuk A4 zone will be perforated 'at approximately 7642'- 7662' MD and hydraulically fracture 0Perf°_rated ~c~stimulated. Contact me with any questions at (907) 659-7519. M. T.

Johnston Commissioner State of Alaska Alaska Oil & Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Subject: Confidential-West Goldhill perforating and testing. Dear Mr. Commissioner: West Goldhill was perforated on 10/13/97 via CTU with 20' of 1-11/16" hollow carrier, 4 SPF, 0 deg phasing and 3.2 gram charges. The perforating guns were located using PDS memory gamma-ray/CCL logs and a flag on the coiled tubing at 11,000 ft MD. The well was perforated from 10,934' MD to 10954' MD (9,120 - 9,140' TVD) On 10/16-17/97 an acid fracture with foam diverter was pumped. The treatment consisted of 295 bbls of nitrified 12% HCL with additives in 4 stages separated by 55 quality foam diverter consisting of 29 barrels of gelled water and approximately 40 MSCF of nitrogen per stage. The flowback began as soon as the stimulation equipment was rigged down and off location. The Production Testing Services flowback report is attached. This data is confidential. After the well was stabilized, the well began flowing into the KRU 2F pad flowline. Testing was done intermittently. Because of the amounts of fluid and gas coming from the well, it was decided to test the well for a longer time than the originally anticipated two weeks. Currently, the well is scheduled to be tested on Tuesday and Saturday. If you have questions, please call John Braden at 263-4536 or James Trantham at 265-6434.

The status of the well is waiting on equipment to perforate the well. The firing head equipment for CTU perforating needs to be modified for safety reasons. Estimated date for the equipment to be ready is in four weeks. The next planned event is to stimulate the well and to flow test. We will keep you informed as events unfold. If you have any questions or require any further information, please contact me at 265-6434 or Mike Zanghi (ARCO Kuparuk Drill Site Development Supervisor) at 265-6206.

The request for approval of the new casing design was verbally approved on 4/28/97 and all operations were completed on 5/4/97. Included with the application is a schematic of the new casing design once the repair was made. Repair of the 9-5/8" intermediate casing on the West Goldhill well was necessary because of parted casing at 430' MD. The casing had parted while attempting to locate the position of a slow thread leak in the casing string. Repeated testing of the 9-5/8" had washed out and weakened the threads at this connection, causing it to fail prematurely when pressure testing with a test packer to locate the leak. Repair of the 9-5/8" casing was done by tying back 7" casing from the 7" liner top to surface, and cementing the casing in place. If you have any questions or require any additional information on this matter, please contact me at 263-4622. Sincerely, William S.

The test was drawn out slightly by tower change midway through the test. After the fresh crew's safety meeting the test was continued with-out missing a beat. This, to me, exhibits familiarity by both crews to a comparable standard procedure. The test went well with no failures observed. John Crisp (Parker Tooipusher) conducted today's test with Donnie Lutrick (Arco drilling foreman) in attendance. This rig has one of the better procedures for testing the BOPE and a methodical search for the failed components. -~' SUMMARY: I witnessed the initial BOP test on Parker rig #245.

The permit to drill does not exempt you from obtaining additional permits required by laxv from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Comlnission's internal use. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling beloxv the surface casing shoe must be given so that a representative of the Commission max' witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope D avid~ W."J,oiins{o-n N Chairrhan ~ ) ' BY ORDER OF T DMMISSION dlf/Enclosures CC: Department of Fish & Game, Habitat Section w/o cncl.

The well is designed to penetrate the Kuparuk, Sag River, Ivishak and Lisburne formations. Upon completion of either drilling or testing the exploratory tail, the well may be reverted back to a Kuparuk well. Attached find the information required by 20 ACC 25.005 (c) for your review. Other pertinent informatio, ~ attached to this application is confidential data including the following: 1) Pressure information as required by 20 ACC 25.035 (d) (2). 2) Prediction of overpressured strata as required by 20 ACC 25.033 (e). 3) Annulus pumping request as required by 20 ACC 25.005 (c) (10). There are no shallow hazards expected at West Goldhill, such as shallow gas. There have been 17 wells drilled on KRU 2F pad and shallow gas has not been encountered. Therefore, ARCO requests a waiver from 20 ACC 25.005 (c) (8). Please note that ARCO does not anticipate the presence of H2S in the formations to be encountered in this well. However, there will be H2S monitoring equipment operating as is the usual case while drilling wells in the Kuparuk field. If you have any questions or require any further information, please contact me at 265-6434 or Mike Zanghi (ARCO Kuparuk Drill Site Development Supervisor) at 265-6206.

Presented by Baker Hughes INTEQ West Goldhill Exploration Well PRESStJRE ANALYSIS AND PREDICTION (per 20 ACC 25.005 (c) (7) and 20 ACC 25.033 (e)) DISCUSSION: An analysis and prediction of overpressured strata was pedormed for the Goldhill, West Goldhill, and Cache wells as required by AOGCC regulations. ARCO does not expect to encounter abnormal pressure from any zones. The prediction is based on an evaluation of offset wells KRU 1 E-06, W. Sak #1, Colville #1, East Ugnu and Kalubik Creek #1). Attached are the following: Mud weight versus depth graph for these wells. Sonic log interval transit time analysis for KRU 1E-06. Pore pressure, frac pressure & anticipated mud weight graph. There are no shallow hazards (such as shallow gas) expected at West Goldhill. There have been 17 wells drilled from KRU 2F pad and shallow gas has not been encountered. Therefore, ARCO requests a waiver from 20 ACC 25.005 (c) (8).

Upon analyzing the risk, the decision is to "reduce or control" the risk to allow for evaluation of the exploration tail is as follows. A larger surface casing will be set. This allows for the ability to topset or bottom set the Kuparuk interval. The Sag River formation will be topset with 7" casing and Parker 245 will drill out a 6-1/8" hole. Logging of Sag River and Ivishak formations will occur prior to drilling into the Lisburne formation. The exploration tail will be cased with a 5" liner if testing the well is warranted. The 9-5/8" and 7" casing shoes will be tested to leak-off or to a maximum of 16 ppg EMW upon drilling 10 foot of new formation. RECEIVED ,lAN ~ ~ 1997 Alaska Oil & Gas Cons. A~hora~ AI,.~ULAR PUMPING OPERATIOho West Goldhill Incidental fluids developed from drilling operations will be pumped down the surface/production casing annulus of an existing well or the nearest dedicated disposal well (2M-23). (Note that cement rinseate will not be injected down the dedi¢~,ted disposal well but will be recycled or held for an open a, nnulus.) The open annulus will be left with a non- freezing fluid during any extended shut down (> 4 hr)in pumping operations. The West Goldhill surface/intermediate casing annulus will be filled with diesel after setting the production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations on significant hydrocarbons, the annulus will later be sealed with cement from the surface shoe to the base of the permafrost, with Arctic pack fluid or diesel from the base of the permafrost to the surface, if the surface shoe is within 200' TVD of the top of the hydrocarbons. Alternatively, if the hydrocarbons are far below the shoe then sufficient cement volume will be pumped during the production cement job to cover the formation. It is requested that West Goldhill be permitted for annular pumping occurring as a result of drilling operations, per proposed regulations 20 AAC 25.080. Any zones containing significant hydrocarbons will be isolated prior to initiating any annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Please reference the enclosed directional drilling plan for other formation markers in this well. A list of all publicly recorded wells within 1/4 mile of the disposal operation is included in this permit application. Surface casing will be set in the Cretaceous shales below the base of the West Sak Sands. These 300-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow. The surface casing shoes will be set +_200' vertical below the base of the West Sak into the heart of the shales. The maximum volume of fluids pumped down the annulus of this well will not exceed 35,000 bbls without the specified permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1500 psi, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) * (Surf. Shoe TVD) + 1500 psi Max Pressure = 3468 psi The surface and intermediate casing strings exposed to the annular pumping operations are determined to have sufficient strength by using the 85% collapse and burst ratings listed below.
