Hilcorp Cook Inlet PODs approved by state
These three small gas fields are on the west side, and were first unitized in the 1960s and 1970s; there is also a storage lease Kristen Nelson Petroleum News
The POD approved for Ivan River is the 51st for the unit, which was formed in 1967 by Standard Oil Company of California and currently has some 2,295 acres and two participating areas, the Sterling-Beluga Gas and Tyonek Gas PAs. Hilcorp took over as operator in 2012 and through February produced 5.156 billion cubic feet of gas. Since it was formed, Ivan River has produced 87.627 bcf.
The division said Hilcorp increased annual production at Ivan River by nearly 429%, producing 772.98 million cubic feet of gas in calendar year 2020, compared to 146.16 mmcf in 2019.
The company perforated the Sterling A5 sands in the IRU 11-06 well in July, the division said, and after producing 36.24 mmcf in January through June of 2020, the well produced 457.85 mmcf July through December.
In September the company perforated the Sterling B2 sands in the IRU 44-36 well, which had no production January through August and had been shut-in since 2008; it produced 254.36 mmcf from September through December.
In its 51st POD Hilcorp will evaluate delineation opportunities in the PAs and evaluate a rig workover on the IRU 11-06 well.
Lewis River The POD approved for Lewis River is the 46th for the unit, formed in 1977 by Cities Service Oil Co. There are three state leases, 620 acres, in the unit, and two PAs, LRU Gas Pool No. 1 and LRU Gas Pool No. 2.
Hilcorp took over as operator in 2012 and through February has produced 2.817 bcf of gas. From inception, Lewis River has cumulative production of 16.211 bcf.
The division said Hilcorp increased annual production at Lewis River by nearly 118%, producing 400.79 mmcf of gas in 2020, compared to 183.99 mmcf in 2019. All production was from a single well, the LRU C-01RD.
In its 46th POD, Hilcorp will continue to produce from LRU Gas Pool No. 2 PA, the division said, while evaluating opportunities to drill delineation wells at the unit.
Hilcorp amended its 46th POD plans to include perforating a new Sterling sand in the LRU A1 well, which has been shut-in since 2009.
SPretty Creek The Pretty Creek POD is the 43rd for that unit. The unit was formed in 1977 by Union Oil Company of California and currently includes 12 tracts covering 4,550 acres all within the Beluga PA, which as of February has cumulatively produced 9.613 bcf of gas.
Hilcorp took over as operator in 2012 and has since produced 147.8 mmcf of gas from the unit.
“In August, 2019, however, production ceased and Hilcorp began work to restore production,” the division said.
Hilcorp made multiple attempts to return the PC-02 well to production but was not successful.
In addition to the work on that well, “Hilcorp conducted a regional study on the Sterling sands for its Westside satellite fields (PCU, Ivan River Unit and Lewis River Unit). Based on this study, Hilcorp anticipates perforating additional Sterling sands in the PC-02,” the division said.
During the 43rd POD, Hilcorp plans to continue evaluating the potential of drilling a “twin” well to the PC-4 to access Sterling sands discovered in the regional study and conduct a coiled tubing fill cleanout of the PC-02 “to access and perforate the potential Sterling sands targets,” the division said.
Pretty Creek gas storage lease This is the 17th POD for the Pretty Creek gas storage lease, ADL 390776, originally granted to Union Oil Company of California in 2005 and amended in 2011. Hilcorp took over as operator in 2012. In 2015 the division approved a request to extend the lease for an additional 10-year term.
There are some 1,999 acres in the lease which uses two gas storage horizons for storage operations, the division said, the Sterling 45-0 gas sands and Beluga 51-5 gas sands.
Hilcorp uses the PCU No. 4 well for storage operations. Through February, Hilcorp has cumulatively stored 6.67 bcf of gas and withdrawn 6.12 bcf of gas.
During the 16th POD, Hilcorp injected 320.65 mmcf and withdrew 613.99 mmcf, compared to injecting 41.91 mmcf and withdrawing 177.39 mmcf the previous year.
Hilcorp plans to continue using the lease for gas storage during this POD period, the division said, but the company’s long-term activities “will include a potential secondary compressor to allow the reservoir to be depleted to a lower pressure, thereby maximizing recovery.” The division said Hilcorp has not yet determined when that activity would take place.
