Progress of the Enhanced Recovery Project/Reservoir Management Summary Production was from 8 wells with gas injection into one well. Static pressure surveys were obtained from wells 131-14, B1 -18A, BI -36 and 131-38. Table 4 contains a summary of the static reservoir pressure readings acquired in 2014. The total volume of oil produced from the Badami reservoir during the report period was 392,464 STBO. A total of 555,615 MSCF of gas was produced of which 3,881 MSCF was injected back into the producing formation. No new wells were drilled and completed during the reporting period. Well disposition is detailed in Table 1. The oil production and gas disposition history of the field is shown in Figure 1 and Figure 2 respectively. 2. Voidage Balance Production and injection volumes and reservoir voidage by month are detailed in Table 2 and Table 3. Cumulative voidage for 2014 was negative 697,784 reservoir barrels. 3. Reservoir Pressure Monitoring Four static pressure surveys were taken at Badami during the report period and are listed in Table 4. These surveys show that the pressures in the individual lobes of the reservoir continue to deplete over time consistent with the depletion drive recovery method employed in the field. 4. Production Logging No production logging was conducted during the report period. 5. Special Monitoring No special monitoring was performed in 2014 Downhole pressure monitoring was performed on B 1-14, B 1-18A, B 1 -3 6 and B 1-3 8 in 2014 as outlined in Table 4. 3 Monitoring of well integrity and surveillance activity on the Class I disposal well, B 1- 01, was completed in 2014 and will continue pursuant to statutory requirement. 6. Evaluation of Well Testing and Allocation Table 5 is a summary of well testing frequency for each of the Badami wells. Daily oil production allocation to each well is accomplished by pro -rating the oil rates from the most recent well test such that the total oil produced from all wells equals the amount measured by the custody transfer pipeline meter. 7. Future Development Plans On November 16, 2012, Savant Alaska LLC ("SALLC"), as Unit Operator, submitted and application to expand the Badami Unit to provide for the orderly drilling of an exploration test well. On March 15, 2013, the DNR approved in part and denied in part the Badami Expansion application. This decision was appealed be SALLC on April 3, 2013 and a subsequent Request for Stay of the activities proposed under the plan of exploration for the unit expansion was submitted to DNR on August 19, 2013. Savant met with DNR Commissioner on October 8, 2014 to discuss the appeal of the Badami Unit Expansion decision. No decision has been made by DNR on the appeal to date. Monitoring of well integrity and surveillance activity on the Class I disposal well, B1- 01, will continue pursuant to statutory requirement. Reservoir pressure data will be acquired during 2015 to monitor Badami reservoir depletion. 8. Review of Plan of Development of Operations and Development The 11th Plan of Development for the Badami Unit (POD) was approved by the Department of Natural Resources for the period of November 16, 2014 through July 15, 2015. Proposed 11th POD activities include: 1. Evaluate the results of hydraulic fracture simulations on wells BI -18A and 131-38. 2. Drill two high angle Brookian Sands development wells 3. Significant preventative maintenance and repairs to the plant and facility 4 9. Status of Well Shut-in for 365 Days or More (20 AAC 25.115) The following wells were shut-in for all of 2014.

This was done to address the fact 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. 7 Table 3: Badami Production/Injection - Reservoir Units BADAMI PRODUCTION I INJECTION - RESERVOIR UNITS 2014 PRODUCTION Jan Feb Mar April May June July Aug Sept Oct Nov Dec 2014 Total Oil (rb) 48,122 42,968 42,510 42,800 45,395 42,570 42,136 41,490 40,556 42,102 39,657 39,900 510,203 Free Gas (rb) 15,185 16,328 14,366 13,281 16,633 14,786 13,575 15,936 16,841 18,382 16,347 18,181 189,843 Water (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 All Fluids (rb) 63,308 59,295 56,876 56,081 62,028 57,356 55,711 57,425 57,398 60,484 56,004 58,081 700,046 2014 INJECTION Water (rb) 0 0 0 0 0 0 0 0 0 0 0 0 0 Gas (rb) 0 0 0 0 0 0 57 232 428 503 610 433 2,263 All Fluids (rb) 0 0 0 0 0 0 57 232 428 503 610 433 2,263 Voidage (rb) -63,308 -59,295 -56,876 -56,081 -62,028 -57,356 -55,654 -57,193 -56,970 -59,982 -55,394 -57,648 -697,784 Oil Formation Volume Factor, Bo 1.300 rb/stb Gas Formation Volume Factor, Bg 0.00058 rb/scf 0.00328 vol/vol Water Formation Volume Factor, Bw 1.0101 rb/stb Notes: (1) Bo from Average of Badami #1 and Badami #5 (lower sand) PVT analysis.
