GENERAL DRILLING AND COMPLETION PROCEDURE KUPARUK RIVER FIELD-Injector KRU 2L-317A Sidetrack Current wellbore status: Surface casing was set at 3461' MD and cemented with full returns to surface. Production hole was drilled to 14,161' MD with the Tarn (Bermuda) interval top (T3.1) picked at 13,462' MD, but there was not enough net pay to complete. The rig is in the process of setting a continuous 15.8 ppg class G cement plug from TD to 13,300' MD to cover the entire Bermuda interval. Then 300' of 17.0 ppg class G cement will be set from 9650-9350' MD for a kick-off plug. The plan is to sidetrack to a new bottom hole location target in the Bermuda interval approximately 1829' north & west of the current BHL as follows: 1. Sidetrack off cement plug at--MD and drill 6-3/4" hole to TD according to directional plan. Run LWD logging equipment with gamma ray, resistivity, and density-neutron tools. Note: If significant .hydrocarbon zones are present abOve the intermediate casing point, sufficient cement will be pumped for isolation in accordance with 20 AAC 25.030(d)(3)(C). 2. Run and cement 5-1/2" L-80 BTC Csg X 3-1/2" L-80 8rd EUE-Mod tapered production casing string with Baker casing seal receptacle at crossover point. 3. Pressure teSt casing to 3,500 psi. 4. Run 3-1/2" L-80 8rd EUE-Mod completion assembly. Sting into polished seal bore wi[h seal assembly and pressure test tubing and annulus to 3,500 psi. 5. Set TWC, ND BOPE and install production tree. 6, Secure well. Rig down and' move out. 7. Handover well to Operations Personnel. (Cement bond log will be run prior to perforating well).

Bummer about the original BHL. What you propose will meet the regulations and you are correct regarding not having to tag the bottom plug since it starts at TD. Kicking off on the upper plug will accomplish the weight test on that one. I am copying the inspectors with this note. Please have the company man contact them with regard to witnessing any plug they wish. I will look forward to seeing the paperwork tomorrow. Have the courier deliver it to our old address.

Nabors 19E has made.short trip, conditioned hole, and is ready to trip out and prepare to set cement abandonment and kick-off plugs. The Tam (Bermuda) interval top (T3.1) was picked at 13, 462' rnd and there are no hydrocarbon bearing intervals present above this depth. We propose setting a continuous 15. 8 ppg class G cement plug from TD of 14,193' to 13, 300' rrd to cover the entire Bermuda interval. Also propose not tagging this bottom plug since in is being set from TD. The open hole above 13,300' md will contain 9.6 ppg LSND mud up to the sidetrack kick-off point (9500' md). We plan to spot 20 bbls of high-vis 9.6 ppg LSND mud and then 300' of 17.0 ppg dass G cement (9650-9350') for l~ck-off plug. The new BHL (2L-317A) targeting the Berrruda interval is 1829' north & west of the abandoned 2L-317.

Drilling fluid practices will be in accordance with the regulations stated in 20 AAC 25.033. 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/fi. 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 2L pad are expected to be --2,300 psi (0.43 psi/fi). Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 8.6 ppg can be predicted as the maximum mud weight needed to safely drill in this formation, assuming a TVD of 5,521'. Target (Midpoint T2 T3) (2300+150)/(0.052'5521)=8.6. ARCO Alaska, Inc. Well Proximity Risks: RECEIVED ,'..~ R 2:5 ~000 Alaaka 0il & Gas Cons. C0~mis,~on The nearest well to 2L-317 is 2L-315. The wells are19.5' from each other at a depth of 600'. Drillinq Area Risks: The primary risk in the 2L-317 drilling area is shallow gas below the permafrost. Therefore the surface hole will need to be drilled with weighted mud (9.5 - 10.2 ppg) to avoid underbalancing the hole. Another observed problem in the area is possible lost circulation at approximately 3,300' TVD and in the Tarn formation. Analysis of pressure data from offset wells shows that a mud weight of 9.0-9.,5 ppg will provide sufficient overpressure to safely drill, trip pipe, and cement the well. The 9-5/8" casing shoe will be tested to leak-off, or to a maximum equivalent mud weight of 16.0 ppg upon drilling out of the casing. Annular Pumpin.~ O~3erations: Incidental fluids developed from drilling operations will be either injected into an approved annulus on the same pad 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 2L-317 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. F_ollowin.q_drilling operations, ARCO Alaska, Inc. will submit application for approval of 2L-317 f-°r ~-hn'ular 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 AOGCC. 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 ARCO Alaska, Inc.

The well is accessed via a new gravel road originating at 2M Pad. Nabors Rig 19e will drill the well. If commercial, the well will also completed with Nabors 19e. Attached is the information required by 20 AA(::; 25.005(c). There will be no reserve Pit for this well. Waste drilling mud will be disposed of down the annulus of an existing well on 'Drillsite 2L (subject to AOGCC approval), or hauled to a KRU Class II disposal well. All cuttings generated will be preferentially ground at the on-site ball mill and injected down an approved, existing well annulus on 2L pad or stored temporarily onsite or hauled to the Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. The TD of this well. will be in the Tarn formation. H2S has not been encountered in this region in any' stratum shallower than the Lisburne Formation. Therefore, ARCO has not included an H2S contingency plan with this Application, and requests an exemption from the. H2S requirements. However, all drilling mud, cores.and produced fluids exiting'the, wellbore.'.. will be monitored for detectable levels of H2S. The following are ARCO's designated contacts for reporting responsibilities to the Commission: 1) Completion Report Sharon AIIsup-Drake, Drilling Technologist 263-4612 (20 AAC 25.070) 2) Geologic Data and Logs Doug Hastings, Geologist 265-6967 (20 AAC 25.071) If you have questions or require additional information, please contact Bill Lloyd at 265-6531 or me at 265-6120 in our Anchorage office.
