PODs submitted for small inlet gas fields
Kristen Nelson Petroleum News
The Alaska Division of Oil and Gas has received plans of development for three small Cook Inlet gas fields from operator Hilcorp Alaska LLC. The plans cover June 1 this year through May 31, 2020.
All are older fields on the west side of the inlet: the POD for Ivan River is the 49th for that unit; the Lewis River is the 44th for that unit; and that for Pretty Creek is its 41st.
Cook Inlet gas production was 83,108.993 million standard cubic feet last year, according to data from the Alaska Oil and Gas Conservation Commission. Of that total, Hilcorp said Ivan River produced 184.9 million standard cubic feet, while Lewis River produced 145 million cubic feet and Pretty Creek produced 54.5 million cubic feet.
Ivan River At Ivan River, Hilcorp had no development or exploration plans for the 2018 POD period. No new wells or workovers were planned and no major facility upgrades.
Hilcorp said there was no production from the Sterling-Beluga gas participating area during 2018; production from the Tyonek PA averaged 0.507 million standard cubic feet per day.
Two wells are the field, IRU 14-31 and 13-31, are being used as disposal wells for Hilcorp’s west side operated fields - Lewis River, Pretty Creek, Ivan River and Stump Lake.
During the 2018 POD, Hilcorp said, it “worked on a comprehensive field study that would lead to possible enhancing production,” including study of pursuing various efficiencies at the field “including evaluation of shut-in wells for potential return to service or utility.” Hilcorp said results of the study were confidential but would be disclosed to the Department of Natural Resources on request.
For 2019, Hilcorp said it did not have any development plans, but would continue production and use of the disposal wells.
Lewis River In its report on work done during the 2018 POD at Lewis River Hilcorp said it “worked on a comprehensive field study,” evaluating the Sterling, Beluga and Tyonek reservoirs for further development, including study of what efficiencies would be pursued. As at Ivan River, Hilcorp said study results were confidential and could be disclosed to DNR on request.
There was no production from the Lewis River gas pool No. 1 PA during 2018, and production was maintained from the Lewis River gas pool No. 2 PA.
For 2019, Hilcorp said it does not have long-range development plans, or any planned exploration or delineation plans.
The company said it will continue to produce from the No. 2 PA during 2019.
Pretty Creek During the 2018 POD, Hilcorp said it proposed to evaluate shut-in wells at Pretty Creek for potential return to service or utility but had not planned any exploration or delineation activities.
Production was to be continued from the Beluga PA. The company also planned to continue use of the Pretty Creek gas storage lease, ADL 390776.
The company planned to add compression at existing surface facilities in the 2018 POD period.
Production from the Beluga PA was continued during the 2018 POD as was use of the gas storage lease.
The company did not do a compression upgrade as it was determined that compression was sufficient at the field, but did install a metering skid on PC No. 2 to be able to flow stored gas from PC No. 4, which allowed gas to be measured separately from PC No. 2, allowing PC No. 2 and PC No. 4 to both flow at the same time.
For 2019, Hilcorp said it plans to evaluate shut-in wells for potential return to service or utility but does not have any exploration or delineation activities planned. Production will continue from the Beluga PA and gas storage will continue.
