Hilcorp submits 48th plan for Lewis River

Hilcorp Alaska operates four natural gas fields on the west side of Cook Inlet, including the tiny Lewis River unit for which the company recently submitted its 48th annual plan of development, or POD. Referred to as the 2023 POD, the 48th plan runs from June 1 through May 31, 2024.
Hilcorp became 100% working interest owner and operator at Lewis River on Jan. 1, 2012, as part of its 2011 acquisition of Chevron’s Cook Inlet assets.
The 620-acre onshore unit was formed by Cities Service Oil Co. in 1977 and went online in 1984.
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.
Lewis River averaged 374 mcf per day in January, down 62.7% from a January 2022 average of 1,003 mcf per day.
Recent POD activity Under the Lewis River unit’s 2021 POD Hilcorp perforated Sterling A sands in the Lewis River A1 well but reported the work was unsuccessful.
Under the 2022 plan from June 1, 2022, through May 31, 2023, Hilcorp said it would continue to evaluate delineation drilling opportunities with the Sterling-Beluga and Tyonek participating areas, with various non-rig well projects planned.
As with the previous POD, throughout the 2022 POD period, Hilcorp continued to produce from the Lewis River Gas Pool #2 participating area, or PA. Also, as with the 2021 POD, there was no production from the Lewis River Gas Pool #1 PA.
2023 plan activities The long-range proposed development activities for the unit include plans to delineate all underlying oil or gas reservoirs and get them into production and maintain and enhance production once established.
However, the company does not have any long-range proposed development activities for the unit during the 2023 POD period.
Hilcorp also does not have any exploration plans for the 2023 POD.
The company does plan to maintain production from the Lewis River Gas Pool #2 PA throughout the 2023 POD period.
In what it calls its drill well program, Hilcorp plans to drill the LRU C-02 well spudding as early as June 30, and targeting Sterling, Beluga, and/or Tyonek sands.
In Hilcorp’s wellwork and workover program, it plans to “perform various non-rig well projects” during the 2023 POD period. These projects may include:
• Coil cleanout operations.
• Adding (or isolating) Sterling or Beluga sand perforation.
At this time, Hilcorp said no major facility upgrades are planned during the 2023 POD.
Finally, Hilcorp does not have any exploration or delineation activities planned in the 2023 POD.
