Progress of the Enhanced Recovery Project and Reservoir Management Summary Production at Badami was restarted September 15, 2005 after a field wide shut-in since August 2003. Production since the 2005 restart was from five wells with gas injection into one well. The field was returned to warm shutdown status starting in late August 2007. Following the field shutdown, static bottom -hole pressures were obtained in Bl - 11A, B1-14, BI -18, 131-21, and B1-36. Static bottom hole pressures were obtained in 131-18, B1-21, and B1-36 during this reporting period. Table 4 contains a summary of the static bottom -hole pressures acquired in 2009. There was no production and injection from or to the Badami reservoir during this reporting period, because of the warm shutdown. No new wells were drilled or completed in 2009. Well disposition is detailed in Table 1. The production and gas disposition history of the field during the report period is shown in Figures 1 and 2. B. Voidage Balance Since no production or injection occurred during the reporting period, Tables 2 and 3 contain only zeros. Cumulative voidage for year 2009 was 0 reservoir barrels. C. Reservoir Pressure Monitoring Three static pressures were taken at Badami during the report period and are listed in Table 4. These statics show that the pressures in the individual lobes of the reservoir have increased since warm shutdown in 2007. All the wells showed an increase in pressure from the statics taken in 2008, with an average rise of some 147 psi over a 12 month period. D. Production Logging No production logging was performed during the report period on wells completed in the Badami reservoir. E. Special Monitoring Other than static bottom hole pressures outlined in Table 4 and daily monitoring of wellhead pressures, no other special monitoring was done during the reporting period. 3 F. Evaluation of Well Testing and Allocation Table 5 is a summary of well testing frequency for each of the Badami wells. Due to the warm shutdown no well testing was done during the reporting period. G. Future Development Plans In 2008, BP and Savant Alaska (partnered with ASRC) concluded a farm -out agreement covering BP's interest in the Badami Unit. As part of this agreement, Savant Alaska plans to drill at least one well to the Red Wolf prospect within the Badami Unit during the '09-'10 winter drilling season. This prospect is targeting Kekituk (Endicott type) reservoirs. As of the time of writing, Savant has drilled one new well (BI -38) to the Kekituk and sidetracked one existing Brookian producer (B1-18) to a new location within the Brookian interval. Additional drilling options, in 2011 and 2012, will be reviewed following the results of these two wells. Monitoring of well integrity and surveillance activity on the Class 1 disposal well, B1-01, will continue as required. Reservoir pressure data will be acquired during 2010 to monitor Badami reservoir recharge. H. Review of Annual Plan of Operations and Development The field was granted a 7th POD by the Department of Natural Resources on July 25th of 2008, which expires November 15, 2010. I.

This was done to address the fact that there are different types of oil in the reservoir with different GOR. (2) Volumes of produced water are reported here although they are not reported in other production allocations and injection reporting due to not being of significant volume. Volumes here are based on tank levels when the water was pumped into the disposal well and are not the actual water production for any given month. 8 Table 3 Badami Production/Injection - Reservoir Units Table 3 Badami Production/Injection - Reservoir Units =�_1 ■L1 tri I1 �:t•] ■1�1•�� C•L' �� 1► l�J_��3_�L•L` 0:��:�1•] 13�J ►1 ti 7 2008 PRODUCTION Jan Feb Mar April May June July Aug Sept Oct Nov Dec 2008 Total Oil (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Free Gas (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Water (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 All Fluids (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 2008 INJECTION Water (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Gas (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 All Fluids (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Voidage (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Oil Formation Volume Factor, Bo 1.300 rblstb Gas Formation Volume Factor, Bg 0.000583 rblscf 0.003276 voVvol Water Formation Volume Factor, Bw 1.0101 rblstb Notes: (1) Bo from Average of Badami #1 and Badami 45 (lower sand) PVT analysis.
