Hilcorp files PODs for small inlet fields
Ivan River and Lewis River are two of smaller gas fields in Cook Inlet; Ivan River production increased substantially last year Kristen Nelson Petroleum News
Hilcorp Alaska has filed plans of development with the Alaska Division of Oil and Gas for two small Cook Inlet gas fields, Ivan River and Lewis River.
Alaska Oil and Gas Conservation Commission records show that, this January, the two fields combined accounted for some 3.2% of the natural gas produced in Cook Inlet.
The POD for Ivan River, submitted March 1, is the 51st for that unit and covers June 1, 2021, through May 31, 2022.
In the previous plan, the 50th, Hilcorp had not proposed any long-range development plans nor did it have any planned exploration or delineation activities.
Ivan River produces from the Sterling-Beluga and Tyonek participating areas and Hilcorp said that cumulative gas production in 2020 was 793.8 million standard cubic feet.
There are also two wells, IRU 14-31 and IRU 13-31, used as disposal wells for the fields the company operates on the west side of the inlet - Lewis River, Pretty Creek, Ivan River and Stump Lake.
The company said it completed three intervention jobs during the 2020 POD period:
*The Tyonek sands were isolated in IRU 11-06 and the Sterling A5 was perforated. After the work was performed in July the well initially came online at 4.4 million standard cubic feet per day.
*The Sterling sands were isolated in IRU 11-06 and the Sterling B2 was perforated in September, with the well initially coming online at 3.1 million standard cubic feet per day.
*The Sterling B1 was perforated in IRU 41-01 this February and the well initially came online at 4.2 million standard cubic feet per day.
The company said there were no major facility improvements in the 2020 POD period.
AOGCC records show that Hilcorp increased production from the unit over the last year. In January 2020 Ivan River production averaged 316 thousand cubic feet, mcf, per day, 0.2% of Cook Inlet gas production. In January 2021, following the intervention jobs performed in 2020, Ivan River production averaged 6,267 mcf per day, 2.8% of Cook Inlet production.
2021 POD In the 2021 plan, Hilcorp said it “is currently evaluating delineation drill well opportunities within the Sterling-Beluga and Tyonek Participating Areas,” but does “not currently have any planned development activities for the unit during the 2021 POD period.”
The company proposes to continue production from the Sterling-Beluga PA and the Tyonek PA “as needed, while continuing to utilize IRU disposal wells.”
The company said it is evaluating a rig workover on IRU 11-06 to replace current tubing and “allow for future isolation of perforations within the well.”
No major facility upgrades are planned for the 2021 POD, but the company said it “will pursue improvements through various well, infrastructure and facility repairs.”
Lewis River Hilcorp submitted the 46th POD for the Lewis River unit on March 1 - the plan covers June 2, 2021, through May 31, 2022.
In the previous, 2020 POD, there were no long-range proposed development activities nor any planned exploration or delineation activities.
Hilcorp said it planned to continue production from the Lewis River Gas Pool No. 2 PA and during 2020, cumulative production from the PA was 400 million cubic feet, with all production from a single well, the LRU C-01RD.
In the 2021 plan, Hilcorp said it is evaluating possible delineation well opportunities, but does not have any long-range proposed development activities planned for the POD period.
Production will be maintained from the Lewis River Gas Pool No. 2 PA.
No major facility upgrades are planned.
AOGCC records show Lewis River production averaged 1,465 thousand cubic feet, mcf, per day in January 2020, 0.7% of Cook Inlet production, dropping to an average of 953 mcf per day in January 2021, 0.4% of Cook Inlet gas production.
