PREPARED BY: John Patton Sperry-Sun Drilling Services Logging Systems Anchorage, AK End of Well Logs And Data DS 2U-TAB-01, Parker 245 The following information was derived from in house evaluations of well cuttings collected at the Parker 245 rig site during the drilling of well 2U-TAB-01. The lithological evaluation was performed for a zone of interest section of this well. The Sample Catchers on location performed their duties on a twelve hour tour basis. The method of lag calculations used for depth tagging the samples were derived from bore hole and surface equipment geometry. Sample evaluations were performed by John Patton, Sperry-Sun Drilling Services' Geologist/Logging Engineer at our Anchorage Lab. John was able to give an interpretive analysis of lithology by utilizing FE/MWD data recorded from the well site. Company Company ARCO Exploration ARCO Oil and Gas ARCO Alaska, Inc.

The well is designed to penetrate and test the production potential of the Tabasco sands southwest of 2U pad. Depending upon log results, the well will be production flow tested through the KRU facilities for a period of time in an effort to delineate the reservoir and test the completion technique. The well is designed with a slotted liner installed through the pay sands which is designed to control sand production expected in these unconsolidated formations. Following the production flow test, if commercial reserves are determined, the well is planned as a possible infill injector well. Please find attached information as required by 20 AAC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1) Form 10-401 Application for Permit to Drill per 20 AAC 25.005 (a). 2) Fee of $100 payable to the State of Alaska per 20 AAC 25.005 (c) (1). 3) A directional plat showing the surface and bottomhole locations proposed for the well per 20 AAC 25.005 (c) (2). Note the north hard line imposed to comply with the AOGCC requirement for a 500' setback from the governmental quarter section line. 4) Directional plots and proximity calculations in accordance with the requirements of 20 AAC 25.050. 5) Diagrams and descriptions of the BOP and diverter equipment to be used as required by 20 AAC 25.035 (a) (1) and (b). Note that due to the pressures expected in the Tabasco sands, ARCO proposes to test the 5000 psi BOP equipment to a max[,~q~~ ~ '~.'~ 3000 psi, pending AOGCC approval per this letter. _~ ~ ~ ~'' ~ 7 997 ARCO Alaska, Inc. is a Subsidiaw of AtlanticRichfieldCompany Alask~ 0~ ~ G~s Cons, Please note that due to the extensive number of KRU wells which have penetrated the Tabasco sands in this area, ARCO has a clear understanding of the formation pressures to be encountered. As a result, no overpressured strata is expected in this area. There are also no shallow hazards expected at 2U-Tab-01, such as shallow gas. There has been sixteen (16) wells drilled from KRU 2U pad, and no occurrences of shallow gas or other hazards have been observed. An exception to the requirements set out by 20 AAC 25.033 (e) and 25.061 (a) are hereby requested for this APD because of this regional experience. A prediction of the maximum downhole and surface pressures which may be encountered however are included in this APD per 20 AAC 25.035 (d) (2). 6) A complete proposed casing and cementing program is attached as per 20 AAC 25.030. A wellbore schematic is also attached visually depicting the proposed well design. 7) The drilling fluid program, a schematic diagram and description of the drilling fluid system to be used, in addition to the requirements set forth in 20 AAC 25.033 are attached in this APD package. 8) A copy of the proposed drilling program, including a request for approval of annular pumping operations is attached. 9) Also 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 functioning on the rigs as is the standard operating procedure in the Kuparuk River Unit drilling operation. 10) Please note that because of the large volume of regional information available in this area, ARCO considers this well to be a delineation well, and as such, no mudlogging operations such as type log generation and sample catching are planned. An exception to the requirements detailed in 20 AAC 25.005 (c) (8) is thus requested. Please note that the anticipated spud date for this well is September 19, 1997. If you have any questions or require further information, please contact Tom McKay at (907) 265-6890 or Steve Robinson at (907) 263-4290. Sincerely, Thomas W.

Notes- Drilling fluid practices will be in accordance with the appropriate regulations stated in 20 AAC 25.033. A clean, new Iow solids system displaced into well after drilling out and running F.I.T. MASP' Maximum anticipated surface pressure is calculated using a surface casing leak-off of 13.5 ppg EMW and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur before a surface pressure of 1,806 psi could be reached. Therefore, ARCO Alaska, Inc. will test the BOP equipment to 3000 psi. (The leak off EMW was chosen based on an open hole leak-off test on 2U-05 taken to 13.4 ppg; surface casing was set at 2,990' TVD.) The nearest existing well to 2U-Tab-01 is 2U-05. As designed, the minimum distance between the two wells would be 14.9' @ 250' MD. Annular Pumping Activities: Incidental fluids generated 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 well on DS 2U, or another KRU drill site. That annulus will be left with a non-freezing fluid during any extended shut down (> 4 hr) in pumping operations. The 2U-Tab-01 surface casing / production tubing annulus will be filled with diesel and/or non-freezing brine after setting the 5-1/2" slotted liner and prior to the drilling rig moving off of the well. Drilling Area Risks: 'Risks in the 2U-Tab-01 drilling area are limited to lost circulation and potential borehole instability in the Tabasco formation. Lost circulation will be addressed with lost circulation material (LCM) and reduced circulating rates as needed. Based on previous DS 2U drilling results, 10.4 ppg mud should be adequate to control both the West Sak and Tabasco formation pressures without resulting in lost circulation. The 7-5/8" casing shoe will be tested to an equivalent mud weight of 13.5 ppg upon drilling out of the surface casing. Although 2U-Tab~01 will be the first time AAI has tested the potential of the Tabasco reservoir in the 2U area, it is not a true exploratory well since we have drilled through this formation many times in nearby Kuparuk wells. For this reason, AAI requests that the ,,. requirements listed in 20 AAC 25.033 (e) and 20 AAC 25.061 (a) (pertaining to predicted overpressured strata and seismic refraction/reflection analysis, respectively) be waived for the drilling of 2U-Tab-01.

The well is designed to penetrate and test the production potential of the Tabasco sands southwest of 2U pad. Depending upon Icg results, the well will be production flow tested through the KRU facilities for a period of time in an effort to delineate the reservoir and test the completion technique. The well is designed with a slotted liner installed through the pay sands which is designed to control sand production expected in these unconsolidated formations. Following the production flow test, if commercial reserves are determined, the well is planned as a possible infill injector well. Please find attached information as required by 20 AAC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1) Form 10-401 Application for Permit to Drill per 20 AAC 25.005 (a). 2) 3) 4) Fee of $100 payable to the State of Alaska per 20 AAC 25.~05 (c) , .. (1). ~ ~: ~,~ '.~ A directional plat showing the surface and bottomhole locations proposed for the well per 20 AAC 25.005 (c) (2). Note the nodh ~ '~ 1997 hard line imposed to comply with the AOGCC requirement.,.~.,~s~a ~l~r&a,~s Cons. 500' setback from the governmental quarter section I~fie. Anch0rag(~ Directional plots and proximity calculations in accordance with the requirements of 20 AAC 25.050. 5) Diagrams and descriptions of the BOP and diverter equipment to be used as required by 20 AAC 25.035 (a) (1) and (b). Note that due to the pressures expected in the Tabasco sands, ARCO proposes to test the 5000 psi BOP equipment to a maximum of 3000 psi pe-'~'-Sing AOGCC approval per this letter. ARCO Alaska, Inc. is a Subsidiary of AtlanticRichfieldCompany Please note that due to the extensive number of KRU wells which have penetrated the Tabasco sands in this area, ARCO has a clear understanding of the formation pressures to be encountered. As a result, no_ overpressured strata is expected in this area. There are also'no shallow hazards ~xpected at 2U-Tab-01, such as shallow gas. There has been sixteen (16) wells drilled from KRU 2U pad, and no occurrences of shallow gas or other hazards have been observed. An exception to the requirements set out by 20 AAC 25.033 (e) and 25.061 (a) are ~_e_~eby re. quest.ed for this APD because of this regional experience. A prediction of the maximum downhole and surface pressures which may be encountered however are included in this APD per 20 AAC 25.035 (d) (2). 6) A complete proposed casing and cementing program is attached as per 20 AAC 25.030. A wellbore schematic is also attached visually depicting the proposed well design. 7) The drilling fluid program, a schematic diagram and description of the drilling fluid system to be used, in addition to the requirements set forth in 20 AAC 25.033 are attached in this APD package. 8) A copy of the proposed drilling program, including a request for approval of annular pumping operations is attached. 9) Also 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 functioning on the rigs as is the standard operating procedure in the Kuparuk River Unit drilling operation. 10) Please note that because of the large volume of regional information available in this area, ARCO considers this well to be a delineation well, and as such, no mudlogging operations such as type log generation and sample catching are planned. An ~_.~.e..x. ception to the requirements detailed in 20 AAC 25.005 (c) (8) is thus requested. Please note that the anticipated spud date for this well is September 19, 1997. If you have any questions or require further information, please contact Tom McKay at (907) 265-6890 or Steve Robinson at (907) 263-4290. Sincerely, Thomas W. McKay, P.E':.
