Go~nisRian Anchorap~ o~D~ -' l (~~ ~~- `~ ~ Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Z- Pad that were treated with corrosion inhibitor in the surface casing by conductor annulus. The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

However, in this case you will be perforating additional zones in the same formation. I think this is a key distinction from the wells on L pad. There is also a tract agreement in place for this well. Based on those facts, your request to add the A sand perfs is acceptable. Please keep us informed with regard to the activities. Please plan to submit a sundry regarding this request on Monday. Good luck, make oil. Tom Maunder, PE AOGCC "Smith, Bruce W" wrote: BP would like to add additional perforation into the well Z-101, AP1#50-029-22978-00. This well is currently under Tract operations. The original perforations were in the C sands of the Kuparuk formation, these sands were frac'd. Perf depths 9552-9578 These sands were not productive. Between 0 and 30 bbls of total production over 24 hours. Well was shut-in and freeze protected while evaluating future options. BP would like to add additional perfs in the Kuparuk A5 zone. Perf interval of interest are 9702.9684 MD (6728.6712 TVDss. There is no plan at this time to frac this interval. If this zone is not productive, it is planned to shut-in and freeze protect, while we re-evaluate other uses for this wellbore. Bruce W.

P.O. Box 196612 Anchorage, AK 99519-6612 Subject: PBU Tract Operation, ADL 028245 Z-101, Kuparuk Formation Dear Mr. Pospisih The Commission received your letter dated February 21, 2001, requesting permission to commingle undefined pool production from the Kuparuk formation with fluids from the Prudhoe Pool IPA. Your request is for surface commingling only and states there will be no downhole commingling of formation fluids from the formations comprising the Prudhoe Pool. Commingling will take place as the produced fluids from Z-101 are transported to PBU gathering facilities. In addition to commingling, you have requested a waiver from the gas-oil ratio limitations of 20 AAC 25.240 for the duration of the evaluation, up to one year. The Commission approves your request for surface commingling contingent on the following conditions for a period of up to one year or as limited by the Division of Oil and Gas Tract Operation permit. Production from Z-101should be reported separately to the Prudhoe Bay Field, Kuparuk River Pool, pool number 640140, for those months the well is tested. Allocation procedures agreed with the Division of Oil and Gas will suffice for production reporting during the evaluation period. At least two well tests per month are required for commingled production allocation. , Our understanding is that BPX will be gathering fluid samples for PVT analysis, conduct pressure tests and monitor GOR performance as part of the surveillance activity for this project. We are interested in the PVT properties and pressure performance and would appreciate a review of the results when the evaluation is complete or as the data is gathered. We look forward to hearing results of this test. If there any questions, contact Jack Hartz at 279~ 1433 ext. 232.

As I said before, you guys did your homework. Based on the fault interpretation out there, your block does look to be wet in the "shallows". We will all have to be mindful of how broken up the geology is out West and that it is possible that this zone will have oil in it in other fault blocks. If you have any questions, please call. Tom Maunder Subject: Date: From: To: Re: [Fwd: Z- 101 Intermediate Cementing] Fri, 13 Oct 2000 19:22:23 -0000 Robert Crandall <Bob_Crandall~admin.state.ak.us> Tom Maunder <tom_maunder~admin.state.ak.us> This is an interesting situation because it's typical for Kuparuk, West Sak, Ugnu and Sagavanirktok pay in the Western Prudhoe Bay and Eastern Kuparuk River Units. Large volumes ofbiodegraded oil in the mid twenty to mid teen api range are present in fault controlled accumulations throughout this area. Taken together this fairway holds billions of barrels. Problems related to complex pay distribution, high viscosity oil and low reservoir temperatures will strongly affect ultimate recovery here but even so we've had recent estimates of up 400 PBU wells being drilled from 4 new pads and existing infrastructure in this trend. In this case Tom was looking at a Z-pad Kuparuk River pool (fault separated from the S-pad Kupamk River pool?) well design. We checked an adjacent expl. well (Highland St.) and found lots of oil in the West Sak, a little in the Ugnu and a big fat oil sand in the Sagavanirktok (@ 3200' md) The Sag oil is probably cold and thick but we have always treated these a potential resource, even though the operators frequently object. This well was less than a mile from Z-pad. Wells on Z-pad have oil in only a few West Sak sands and the overlying section is wet. This is an interesting area and is one we need to pay attention to.

It looks like you have done your upfront work and I don't think there will be anything further necessary. One item I will need to add to the package is the postable hazards note. You can get with Allen for an example. The section you have in the package you prepared is good, but we do like to see a bullet type that can be posted in the doghouse. You can send it by email and I will add it to the package. Thanks again, give a call if you have any questions. Tom "Isaacson, William S" wrote: > > > > Tom, This note is to confirm our conversation of Wednesday October 11, 2000, regarding intermediate casing cementing requirements on the Z-101 well. As we discussed, the need to bring cement above the Ugnu reservoir section, because of producible hydrocarbons, should not be required. This issue was researched thoroughly in the well planning process because of the hydrocarbons encountered while drilling the Ugnu intervals in the recent Aurora S-Pad wells. Several wells in the Z-Pad area with logs across the Ugnu intervals were reviewed. Those wells which originated from Z-Pad (Z-35, Z-08, & Z-03) show no signs of producible hydrocarbons from the Ugnu intervals. As per the Gologists and Reservoir Engineers, the Ugnu in this area is wet and believed to be down in the water aquifer. In regards to your questions of the hydrocarbons found within the Ugnu interval at-3200' TVDss in the offset well 'Highland State'. It is believed that there is a large fault between the Z-Pad Ugnu penetrations and the Highland State Ugnu penetration. The interval you reference in the 'Highland State' well at -~3200' TVDss, is found approximately 230' TVD deeper in the Z-Pad and planned Z- 101 penetrations, thus placing them down in the water aquifer. Therefore, as per the proposed cementing design submitted in the Z-101 Permit to Drill, we will plan to bring cement ~-500' above the Schrader interval and leave the Ugnu uncovered. If further information is required to meet your approval of the proposed plan, please contact me and I can do what we need to do. Thanks!! William S.

The highest level of H2S ever measured on Z Pad has been 21 ppm from Z-18. DRILLING CLOSE APPROACH: · All wells pass close approach guidelines. SURFACE HOLE SECTION: · Z Pad has a history of gas hydrate problems while drilling both the surface and intermediate hole sections. On the three most recent Z Pad wells gas hydrate problems were minimized in the surface hole and basically eliminated from the intermediate section. By setting the surface casing deeper, down below the SV1 sands rather than above the SV2 sands, hydrates were eliminated from the intermediate hole. In the surface hole, hydrate gas was minimized by bringing the mud weight to 10.2 ppg by the Base Permafrost and by pretreating the mud system with 2 ppb Driltreat (Lecithin). Additional measures include reducing flow rates to ~450 to 500 gpm and keeping the mud temperature cool. · Minor tight hole has been encountered in the clay sections below the permafrost. · Differential sticking could be problematic in this hole section adjacent to the permeable SV Sands. Avoid leaving drill string stationary for extended periods, tighten fluid loss properties of mud, and string in Barofibre prior to penetrating sand intervals. · Lost circulation has not been a problem while drilling in the surface section, however losses have occurred while running and cementing surface casing. Be sure to condition and thin mud Z-101 Permit to Drill appropriately prior to pulling out of the hole to run casing, and once on bottom with casing, bring circulation up slowly and reduce mud viscosities before pumping cement. INTERMEDIATE / PRODUCTION SECTION: · Gas cut mud has been observed in the Ugnu (3196' TVDss) and West Sak (4280' TVDss) sands. This will be controlled with appropriate mud weights. A minimum of 9.3 ppg is recommended. · The Z-101 well path will drill a full section of the HRZ shale. The HRZ has not proven troublesome in the Z Pad area, however precautions will be taken to aid in shale stabilization. Increased mud weights and inhibitive drilling fluids will be used. · The shallow intervals beneath Z Pad are highly faulted. These faults have a history of being conductive and have resulted in several lost circulation incidents. As planned, the Z-101 well path should not cross any faults and has been optimized to avoid cutting any permeable sands near the damaged zones of these faults. However, the possibility of encountering losses still exists. To be prepared for any potential lost circulation, a copy of the 'Recommended Lost Circulation Procedures' and the 'Lost Circulation Decision Tree' will be sent to the rig prior to drilling out in the 8-3/4" production interval. · Differential sticking will be a problem if lost circulation is occurring or if the drill string is left stationary for an extended period or time across the permeable Schrader Sands. · The kick tolerance for the 8-3/4" open hole section would be 55 bbls assuming an influx from the Kuparuk interval at -9696' MD. This is a worst case scenario based on a 9.9 ppg pore pressure gradient, a fracture gradient of 12.5 ppg at the 9-5/8" shoe, and 10.3 ppg mud in the hole. Disposal: · No annular injection in this well. · Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. · Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I wastes to Pad 3 for disposal. Pre-Ricl Work: 1. Set 20" conductor and weld an FMC landing ring for the FMC Gen 5 Wellhead on the conductor. 2.

The highest level of H2S ever measured on Z Pad has been 21 ppm from 7-18. Z Pad has a history of gas hydrate problems while drilling both the surface and intermediate hole sections. On the three most recent Z Pad wells gas hydrate problems were minimized in the surface hole and basically eliminated from the intermediate section. By setting the surface casing deeper, down below the SV1 sands rather than above, hydrates were eliminated from the intermediate hole. In the surface hole, hydrate gas was minimized by bringing the mud weight to 10.2 ppg by the Base Permafrost and by pre-treating the mud system with 2 ppb Driltreat (Lecithin). Additional measures include reducing flow rates to -450 to 500 gpm and keeping the mud temperature cool. The shallow intervals beneath Z Pad are highly faulted. These faults have a history of being conductive and have resulted in several lost circulation incidents. As planned, the Z-101 well path should not cross any faults and has been optimized to avoid cutting any permeable sands near the damaged zones of these faults. However, the possibility of encountering losses still exists. To be prepared for any potential lost circulation, a copy of the 'Recommended Lost Circulation Procedures' and the 'Lost Circulation Decision Tree' will be sent to the rig prior to drilling out in the 8-3/4" production interval. Gas cut mud has been observed in the Ugnu (3196' TVDss) and West Sak (4280' TVDss) sands. This will be controlled with appropriate mud weights. A minimum of 9.3 ppg is recommended. The Z-101 well path will drill a full section of the HRZ shale. The HRZ has not proven troublesome in the Z Pad area, however precautions will be taken to aid in shale stabilization. Increased mud weights and inhibitive drilling fluids will be used. Differential sticking could be problematic in both hole sections. Avoid leaving drill string stationary for extended periods, tighten fluid loss properties of mud, and string in Barofibre prior to penetrating highly permeable sand intervals.
