Review of Sundry Applications 306-365 ConocoPhillips Alaska, Inc. We1l2N-337A Kuparuk River Field, Tarn Oil Pool AOGCC Permit 185-109 Requested Action: ConocoPhillips Alaska, Inc. (CPAI) proposes to abandon the subject wellbore so that the well can be re-entered for a sidetrack. Recommendation: I recommend approval of CP AI's proposed action. Discussion: CPAI proposes to squeeze the existing perforations located at 9960' to 10000' MD, cut and pull the tubing and some ofthe 5-W' production casing, and set a cement plug across the 7-5/8" surface casing shoe. This will prepare the well for sidetracking, which will be discussed in a separate permit to drill application. Mr. Guys Schwartz informed me that the well will be sidetracked to another bottomhole location in the Tam Oil Pool. We1l2N-337A was completed in June 1998 and began production in August of the same year, the well has been shut in since July 2004. The well is located on the periphery of the Tam Oil Pool. Cumulative production from the well is 499 MBO, 470 MMCFG, and 286 MBW. Peak oil production was 910 BOPD in October 1999. The well has had a somewhat erratic production history, as can be seen by the production plot below, and has had a few periods of shut in production. The last period of sustained production, August 2002 through December 2003, showed production averaging approximately 200 BOPD through May of 2003 before declining rapidly and was producing at less than 20 BOPD during the last three full months of production. During the period of rapidly declining oil production the water production from the well remained relatively constant at about 80 to 100 BWPD. The Tam Oil Pool has an active gas and water injection program for enhanced recovery and the behavior exhibited by the subject well could be indicative of water breakthrough. A later attempt, June and July 2004, to resume production from the well was short lived an unable to establish production of more than 100 BOPD. In addition to the low production rates the well has also experienced other operational difficulties. In August 1999 the Operator submitted a sundry application, sundry number 399-146, to temporarily install and test a jet pump in the well in hopes of solving production problems associated with paraffin buildup in the tubing. The description of the propose activity stated, "[t]he production history for well 2N-337 A is characteristic of the 2N periphery producers, with intermittent production followed by periods of shut-in time." The application also stated, "[p]araffin accumulation has been a consistent . . impediment to production, and has resulted in a complete tubing obstruction. The high deviation ofW e1l2N-337 A is considered to be a contributing factor to wellbore cooling and consequent paraffin deposition." 'DID ~ . .......... ..........

Conclusion: Based on the rapid decline in oil production towards the end of this wells productive life, the documented history of production difficulties, and the fact that the well will be sidetracked to a new bottomhole location in the Tam Oil Pool I believe it is appropriate to approve this application.

Chdstenson Commissioner ~,a,t~e ............. '~ 10-403 Rev 06/15/88 Attachment 1 Install Jet Pump Tarn Well 2N-337A Well 2N-337A is located in the periphery of drill site 2N. The production history for Well 2N- 337A is characteristic of the 2N periphery producers, with intermittent production followed by periods of shut-in time. Well 2N-337A has averaged ~ 7,000 bbls/month oil production since the well was brought on-line 9/98, which ranks 14th among the existing fourteen 2N producers. Paraffin accumulation has been a consistent impediment to production, and has resulted in a complete tubing obstruction. The high deviation of Well 2N-337A is considered a contributing factor to wellbore cooling and consequent paraffin deposition. Testing of Well 2N-337A with gas lift indicates that the proposed jet pump installation will result in sustained production. The water injection test at drill site 2N provides an opportunity to utilize injection water as a power fluid source for a jet pump installation in production Well 2N-337A. The jet pump is a reverse circulation pump, and "hard line" with a check valve will tie the injection header to the production annulus. The jet pump will be installed in the production tubing at an open sliding sleeve at 9488', which will result in tubing by annulus communication. A variance for Well 2N-337A is requested for the 90 day period from July 15, 1999 to October 15, 1999 to test the jet pump application. Due to the existing practice of chemical treating injected water, the short duration of the jet pump test (- 90 days), and the low annulus injection rate (- 2,000 bwpd), the existing schedule for chemical treating of injection water is expected to be sufficient for the 90 day jet pump test. Produced water used for injection is currently treated with RU 275 at the Kuparuk production wells. In general, pitting and wall loss corrosion in flow lines typically can not be detected by inspection until a coupon indicates a wall loss of greater than ~ 10 mils/year for at least 2 years. The 1999 coupon data for Kuparuk CPF2 injectors indicates that the average coupon wall loss or pitting corrosion is - 1-2 mils/year. Based on this information, wall loss and pitting in the production annulus is not anticipated for the duration of the 90 day test.

As I understand that you have only two pipelines to Tarn, one for production and the other for lift gas or injection. Since you will need the line for injection, if the for four subject wells are to be lifted during the test it will have to be with the jet pumps, powered by water. We agree this is a reasonable approach and that your efforts should reduce casing corrision to an acceptable level. Therefore testing jet pumps powered by injection water during the Tarn water injection test is acceptable. Blair Wondzell, 7/15/99 Erickson&Versteeg wrote: Blair, Per our phone conversation 7/12/99, verbal approval is requested to proceed with the planned jet pump installations at Tarn. Verbal approval is requested since the opportunity to test the jet pumps is limited to the duration of the Tarn water injection test,. Sundry requirements for the jet pump test were not anticipated, and the issues outlined in the sundry request were only recently recognized. Approval is requested to install jet pumps in wells 2N-319, 2N-335, 2N-33_~TA, and 2N-34.__5 during the ~ 90 day period ending October 15, 1999. Water from the Tarn M.I header will be injected down the 5-1/2" X 3-1/2" production annulus as power fluid for the "reverse circulation" TRICO jet pump. The jet pump will be installed in the 3-1/2" tubing sliding sleeve, which will allow water entry from the annulus to the tubing. This will result in tubing by. annulus communication. A variance is requested for the duration of the test. Due to the existing practice of chemical treating injected water, the short duration of the jet pump test (- 90 days), and the iow annulus injection rate 2,000 bwpd), the existing schedule for chemical treating of injection water is expected to be sufficient for the 90 day jet pump test. Produced water used for injection is currently treated with RU 275 at the Kuparuk production wells. In general, pitting and wall loss corrosion in flow lines typically can not be detected by inspection until a coupon indicates a wall loss of greater than ~ 10 mils/year for at least 2 years. The 1999 coupon data for Kuparuk CPF2 injectors indicates that the average coupon wall loss or pitting corrosion is - 1-2 mils/year. Based on this information, wall loss and pitting in the production annulus is not anticipated for the duration of the 90 day test.

This well is a sidetrack from KRU 2N-337. The productive interval of the new well will be within 500' of a quarter section line and lies within the proposed Tarn Oil Pool. ARCO and partners own all of the adjacent properties. A request for spacing exception will be forthcoming. We request that the AOGCC proceed with processing and approval of Form 401 Application for Permit to Drill prior to the spacing exception being granted. This request is made to allow for continuous drilling rig operations. We intend to drill 2N 337A immediately. Estimated spud date for 2N 337A is June 16, 1998. The well would not be perforated or produced prior to the spacing exception being granted or approval of the pending Pool Rules. In making this request ARCO assumes the liability of any protest to the spacing exception that might be made. We appreciate your consideration of this request.

Maximum Anticipated Surface Pressure: Maximum anticipated surface pressure (MASP) while drilling the production hole is calculated using a surface casing leak-off of 13.5 ppg EMW (0.70 psi/fi) and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur at a surface pressure of 1,357 psi. Therefore ARCO will test the BOP equipment to 3,500 psi after setting surface casing. MASP = (2,300 ft)(0.70 - 0.11) = 1,357 psi Based on offset well data, reservoir pressures in the Tarn sands in the vicinity of 2N pad are expected to be -2,350 psi (0.50 psi/E). Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 9.5 ppg can be predicted as the maximum mud weight needed to safely drill in this formation, assuming a TVD of 5,100'. 2N 337A jt, 06/15/98 ARCO Alaska, Inc. Well Proximity Risks: The nearest wells to 2N 337A are 2N337 and 2N 339. 2N337 has been abandoned and is approximately 650' to the south at TD. 2N339 is 1200' away at the sidetrack point of 2N337A and the wells diverge from there. Drillinq Area Risks: The primary risk in the 2N 337A drilling area is economic risk. 2N 337 was found to be unfavorable and 2N337A is hoped to be more economic. In respect to pressure data, a mud weight of 9.6-10.0 ppg will provide sufficient overpressure to safely drill, trip pipe, and cement the well. Annular Pumping Operations: Incidental fluids developed from drilling operations will be either injected into a nearby annulus or hauled to the nearest permitted Class II disposal well. (Note that cement rinseate will not be iniected down the dedicated disposal well but will be recycled or held for an open annulus.) The open annulus will be left with a non-freezing fluid during any extended shut down (> 4 hr) in pumping operations. The 2N 337A surface/production casing annulus will be filled with diesel after setting production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. We request that 2N 337A be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. Any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. 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 shoe will be set a minimum of 200' vertically below the base of the West Sak into the heart of the shales. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl without the specific permission of the AC)GCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) * (Surf. Shoe TVD) + 1,500 psi = (12.0 ppg) * (0.052) * (2,300') + 1,500 psi Max Pressure - 2,935 psi This pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and production casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: 2N 337A jt, 06/15/98 ARCO Alaska, Inc.
