DNR/DOG/AOGCC 2004 Discovery Well: Conoco Inc. Badami No. 1 Permit #189-117 API No. 50-029-22017-00-00 Sec. 09, T09N, R20E, UM Depth: 13,595’ MD / 12,911' TVD March 7, 1990 Status: Shut-in Location: Central Arctic Slope Area Location Map DNR Unit Map Orders: Complete List Summary: The Badami Oil Pool was discovered in 1990, and developed through a drilling program lasting from 1997 to 1998. The pool has now been penetrated by 19 well bores, most of which are clustered near the center of the Badami Unit. There are 8 additional wells that lie inside of, or within 4 miles of, the unit boundaries. The pool began regular production on August 23, 1998, and peaked at average rate of 7,450 barrels per day during September 1998. However, production rapidly declined to 3,300 barrels per day by January 1999, and the field was shut in from February 4 through April 30, 1999. After facilities were upgraded and remediated, production was restarted on May 1, 1999 and jumped to an average of nearly 5,300 barrels per day during July of 1999. However, by year-end 1999, production declined to an average of less than 3,000 barrels per day, and by July 2003 it averaged less than 1,300 barrels per day from six wells. In August, 2003, the Regulatory Commission of Alaska approved BP’s request to temporarily shut down the Badami oil pipeline and gas products pipeline for approximately two years. BP shut-in production and placed the facilities in “warm shutdown” that same month. Geology: The Badami reservoir consists of a series of turbidite sandstones assigned to the Tertiary-aged Canning Formation. These sandstones were deposited as amalgamated channel sands within mud-dominated submarine fan systems. Published descriptions suggest the reservoirs are complex, consisting of 61 identified fans laid down during seven depositional events, with thin and discontinuous reservoir quality sands. No single well has encountered all of the identified fan systems, but Badami #1 reportedly has the most complete section. The Badami Oil Pool is defined as the accumulation of hydrocarbons common to and correlating with the interval between the measured depths of 9,500 feet and 11,500 feet in the Badami No. 1 well. The reservoir sandstones are very fine-to-fine grained and moderately sorted. Porosity ranges from 15 to 21 percent, permeability ranges from 1 to 400 md, and oil gravity ranges from 21 to 30 degrees API. Structure Map Strat Column Type Log Orig.

There are 8 additional wells that lie inside of, or within 4 miles of, the unit boundaries. The pool began regular production on August 23, 1998,2 and peaked at average rate of 7,450 barrels per day during September 1998.3 However, production rapidly declined to 3,300 barrels per day by January 1999, and the field was shut in from February 44 through April 30, 1999. After facilities were upgraded and remediated, production was restarted on May 1, 1999,5 and jumped to an average of nearly 5,300 barrels per day during July of 1999. However, by year-end 1999, it declined to an average of less than 3,000 barrels per day,6 and by July 2003 field production averaged less than 1,300 barrels per day from six wells.7 In August 2003, the Regulatory Commission of Alaska approved BP’s request to temporarily shut down the Badami oil pipeline and gas products pipeline for approximately two years.8 BP shut-in production and placed the facilities in “warm shutdown” that same month.9 SFD Revised November 30, 2004 1 Bredar, W., 1997, Testimony before the Alaska Oil and Gas Conservation Commission in support of the Application of BP Exploration (Alaska) Inc. to Define the Badami Oil Pool and Establish Well Spacing for Development, July 16, 1997, Conservation Order 402 File, p. 9. 2 Repp, S.A., 1999, Badami Development, 1999, SPE Paper 54604, SPE Western Regional Meeting, Anchorage, Alaska, 26-28 May 1999. 3 Alaska Oil and Gas Conservation Commission, 2004, Production Database 4 Nelson, K., 1999, BP suspends Badami production, Petroleum News, Vol. 4, No. 2, February 28, 1999, http://www.petroleumnews.com/pnads/171276921.shtml 5 Nelson, K., 1999, Aggressive work aimed at making Badami productive, Petroleum News, Vol. 4, No. 6, http://www.petroleumnews.com/pnads/829909748.shtml 6 Alaska Oil and Gas Conservation Commission, 2004, Production Database 7 Alaska Oil and Gas Conservation Commission, 2004, Production Database 8 Petroleum News, 2003, Badami pipeline shutdown approved, Petroleum News, Vol. 8, No. 32, August 10, 2003, http://www.petroleumnews.com/pnads/232460769.shtml 9 Kay Cashman, 2003, BP to mothball Badami, Petroleum News, Vol. 8, No. 25, June 22, 2003, http://www.petroleumnews.com/pnads/638153503.shtml Badami Oil Pool Geology The Badami reservoir consists of a series of turbidite sandstones assigned to the Tertiary-aged Canning Formation. These sandstones were deposited as amalgamated channel sands1 within mud-dominated submarine fan systems.2 Published descriptions suggest the reservoirs are complex, comprising 61 identified fans laid down during seven depositional events, with thin3 and discontinuous4 reservoir quality sands. No well has encountered all of the identified fan systems. The Badami #1 reportedly has the most complete section.5 The Badami Oil Pool is defined as the accumulation of hydrocarbons common to and correlating with the interval between the measured depths of 9,500 feet and 11,500 feet in the Badami No. 1 well.6 The reservoir sandstone is very fine-to-fine grained and moderately sorted.7 Porosity ranges from 15 to 21 percent, permeability ranges from 1 to 400 md,8 and oil gravity ranges from 19 to 29 degrees API.9 (21 to 30 degrees according to operator supplied reservoir statistics10). Initially production rates were expected to reach 35,000 barrels per day,11 but production rates for the apparently complex and compartmentalized pool peaked at 7,450 barrels per day during September 1998, declined to less than 3,000 barrels per day by December 1999, and averaged less than 1,200 barrels per day during July 2003, just before the pool was shut in.12 1 Nelson, K., 1999, BP’s Badami production at half expected rate, Petroleum News, Vol. 3, No. 10, October 28, 1998, http://www.petroleumnews.com/pnads/656633186.shtml 2 Bredar, W., 1997, Testimony before the Alaska Oil and Gas Conservation Commission in support of the Application of BP Exploration (Alaska) Inc. to Define the Badami Oil Pool and Establish Well Spacing for Development, July 16, 1997, Conservation Order 402 File, p. 8 - 9. 3 Nelson, K., 1999, Aggressive work aimed at making Badami productive, Petroleum News, Vol. 4, No. 6, http://www.petroleumnews.com/pnads/829909748.shtml 4 Alaska Oil and Gas Conservation Commission, 1997, Conservation Order No. 402, Badami Oil Field, Badami Oil Pool; http://www.state.ak.us/local/akpages/ADMIN/ogc/orders/co/co400_499/co402.htm 5 Bredar, W., 1997, Testimony before the Alaska Oil and Gas Conservation Commission in support of the Application of BP Exploration (Alaska) Inc. to Define the Badami Oil Pool and Establish Well Spacing for Development, July 16, 1997 Conservation Order 402 File, p. 31. 6 Alaska Oil and Gas Conservation Commission, 1997, Conservation Order No. 402, Badami Oil Field, Badami Oil Pool; http://www.state.ak.us/local/akpages/ADMIN/ogc/orders/co/co400_499/co402.htm 7 EXLOG, 1990, Mudlog Sample Descriptions, Badami No. 1 Well; Alaska Oil and Gas Conservation Commission Well File No. 189-117. 8 BP, 2003, Reservoir Properties supplied by Operator for Alaska Oil and Gas Conservation Commission 2003 Annual Report. 9 Nelson, K., 1999, BP’s Badami production at half expected rate, Petroleum News, Vol. 3, No. 10, October 28, 1998, http://www.petroleumnews.com/pnads/656633186.shtml 10 BP, 2003, Reservoir Properties supplied by Operator for Alaska Oil and Gas Conservation Commission 2003 Annual Report. 11 Kay Cashman, 2003, BP to mothball Badami, Petroleum News, Vol. 8, No. 25, June 22, 2003 12 Alaska Oil and Gas Conservation Commission, 2004, Production Database AAOrder No.DateOperator Description Current BADAMI FIELD BADAMI OIL POOL Current Orders 500 0CO 16-Oct-03BP EXPLORATI Rules regulating sustained casing pressures in development wells within the Badami Field.
