Some of these wells were found to have a void in the conductor by surface casing annulus. The volume of annular void subsequently was filled with a corrosion inhibiter engineered to prevent water :trom 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.

As set forth in the Rule 7, ARCO Alaska is requesting Commission approval to continue water injection into this well. As found in Area Injection Order No. 2, the aquifers described by a 1/4 mile area beyond and lying directly below the Kuparuk River Unit are exempted for Class II injection activities by 40 CFR 147.102(b) (3) and 20 AAC 25.440(c). As such, continued injection will not endanger any Underground Source of Drinking Water (USDW). Well 3K-31 was completed on 6/10/98. The tubing and annulus were pressure tested in preparation for perforating. The well failed to PFF and a one-way tbg to casing leak was identified. The rig was sent back to rerun the completion. The well was re-completed on 7/11/98. The well was perforated and a high pressure breakdown completed. On 7/26/98 the well was put on injection and the inner annulus pressure was noted at 2240 psi. The inner annulus was P/T to 3,000 psi on 7/29/98 and lost 50psi over 30 minutes. We have since reduced the injection rate to approximately 750 BWPD at an average surface injection pressure of 1600 psi to maintain the inner annulus to <2000 psi. Further diagnostic work is being scheduled to identify the leak. SENT BY:ARCO ALASKA '11- 0-08 ' 6:28P1~ ' KPS/WI~I].S/CNST/PROJ~ 007 276 7.542;# 1/ 1 ARCO Alaska, Inc.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Annular disposal of drilling waste will not be approved until sufficient data is submitted to ensure that thc requirements of 20 AAC 25.080 are met. A Formation Integrity Test (FIT) must confirm the adequacy of cement behind surface casing. Cementing records, FIT data. and any CQLs must be submitted to the Commission with an Application for Sundry Approvals (form 10-403) prior to initiating disposal operations. Thc blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of thc MI test before operation, and of the BOPE test performed before drilling below the surface casing shoe. must be given so that a representative of the Commission max' witness the tests. Notice max.' be given bv contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Robert N.

Note: As a dedicated injector, cased hole cement bond logs (SLT-J or CBT) will be run to establish isolation after the cleanout is completed, but prior to perforating. 3K-31 TAB,04/17/98, v.2 DRILLING FLUID PROGRAM, PRESSURE CALCULATIONS, & DRILLING AREA RISKS Well KRU 3K-31 Drillinq Fluid Properties: Density PV YP Viscosity Initial Gel 10 Minute Gel APl Filtrate pH % Solids Spud to 7-5/8" Surface casin~ 9.0-10.0 15-25 15-35 50-80* 5-15 15-40 10-12 9.5-10 +/-10% Drill out to 5-1/2" Intermediate casin~ 8.4-9.6 5-15 5-8 30-40 2-4 4-8 8-10 9.5-10 4-7% Drill out to TD 11.0-11.5 10-18 10-14 30-45 2-4 4-8 4-5 through Kuparuk 9.5-10 <12% Drillinq Fluid System: Tandem Brandt Shale Shakers Triple Derrick Shale Shakers Solids Processing System to minimize drilling waste Mud Cleaner, Centrifuges, Degasser Pit Level Indicator (Visual and Audio Alarm) Trip Tank Fluid Flow Sensor Fluid Agitators *Spud mud should be adjusted to a FV between 50-80 sec/qt to drill gravel beds Notes: Drilling fluid practices will be in accordance with the appropriate regulations stated in 20 AAC 25.033. Maximum Anticipated Surface Pressure: Maximum anticipated surface pressure 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 2,384 psi. Therefore, ARCO Alaska, Inc. will test BOP equipment to 3,000 psi. MASP = (4017 ft)(0.70- 0.11)psi/ft = 2384 psi Maximum anticipated surface pressure is calculated using a intermediate casing leak-off of 13.5 ppg EMW (0.70 psi/ft) and a gas gradient of 0.11 psi/ff. This shows that formation breakdown would occur at a surface pressure of 3,692 psi. Therefore, ARCO Alaska, Inc. will do a one time test of the BOP equipment to 5000 psi, retesting only broken flanges or after the 7 day limit. MASP = (6259 ft)(0.70 - 0.11)psi/ft = 3692 psi Based on offset well data, reservoir pressures in the Kuparuk sands in the vicinity of 3K pad are expected to be 3600 psi (0.57 psi/ft). Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 11.4 ppg can be predicted as the maximum mud weight needed to safely drill in this formation, assuming a TVD of 6348'. Well Proximity Risks: The nearest existing well to 31(-31 is injector well 3K-12. As designed, the minimum distance between the two wells would be 12' at 500' MD. Prior to spud, 3K-12 will be shut in and the annular pressures bled to 0 psi. Drillinq Area Risks: Risks in the 31(-31 drilling area include lost circulation and high pressures in the Kuparuk formation. Lost circulation above the Kuparuk will be addressed with lost circulation material (LCM) and reduced circulating rates as needed. High formation pressures will be addressed by topsetting 5-1/2" casing above the Kuparuk. Either Nordic Rig #2 or a coiled tubing unit will then drill out 4-3/4" hole and run a 3-1/2" liner to TD. Careful analysis of pressure data from offset wells shows that a mud weight of 11.4 ppg will provide sufficient overpressure to safely drill, trip pipe, and cement. The 7-5/8" and 5-1/2" casing shoes will be tested to leak-off, or to a maximum equivalent mud weight of 14.0 ppg upon drilling out of the casing. Annular Pumping Operations: Incidental fluids developed from drilling operations will be hauled to the nearest permitted disposal well or will be pumped down the surface/production casing annulus of an existing permitted 3K Pad well. (Note that cement rinseate will not be injected 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 3K-31 surface/production 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, then sufficient cement volume will be pumped during the production cement job to cover the formation. It is requested that 3K-31 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. 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 = 4022 psi The pressure is very conservative as frictional losses while pumping are not accounted for. The surface and production casing strings exposed to the annular pumping operations are determined to have sufficient strength by using the 85% collapse and burst ratings listed below.
