Hilcorp to start gas flowing from Anchor Pt Seaview field this year

A newly discovered natural gas field - Hilcorp’s Seaview - will soon be online on the southern Kenai Peninsula.

This is not a large development: there is a single pad with one well in place and two more planned, one this year and one next.

The Alaska Department of Natural Resources’ Division of Oil and Gas said April 27 that Hilcorp has filed for authorization for the development phase of the project near Anchor Point, which includes construction of a new natural gas production facility and up to two new wells.

Hilcorp drilled stratigraphic tests in the area in 2017 and applied to the state in the summer of 2018 for an exploration plan which included construction of the Seaview pad and two exploration wells. The pad is on private land at an operating mine site near Anchor Point between the Sterling and Old Sterling highways.

The discovery well, Seaview 8, was completed in December 2018 to a vertical depth of 10,148 feet. Hilcorp said the well was tested for gas in May 2019.

Dave Buthman, Hilcorp senior geologist, told the Alaska Geological Society March 17 that Seaview was one result of the “modern exploration toolbox” - modern airborne gravity gradiometry and magnetic surveys, geologic field surveys, drainage anomaly studies and seismic surveys - the company has brought to the search for natural gas to serve Cook Inlet area markets. He said that Hilcorp would be putting the Seaview pad online this year (see story in March 22 issue of Petroleum News).

The wells

Hilcorp plans to bring the Seaview 8 online as a gas production well late this year, with drilling of the Seaview 9 planned for late this year.

Seaview 8 was drilled some 10,500 feet measured depth to the west-southwest of Seaview pad, with approximately the first 5,500 feet of wellbore perforated to evaluate gas zones and the bottomhole location evaluated for oil.

In May 2019, Hilcorp confirmed gas, perforating and testing Seaview 8 within multiple zones, with targeted gas reservoirs including the Lower Sterling, Beluga and Tyonek formations between 350 and 5,500 feet total vertical depth.

“Based on testing, Hilcorp proposes bringing the well to production for gas and drilling additional delineation/production wells,” the company said. Seaview 9, approved along with Seaview 8 as part of the company’s exploration plan, will extend some 10,000 feet measured depth to the northwest of the pad.

“A third well, Seaview 10, is proposed to be drilled in 2021,” Hilcorp said.

Construction in August

The division said Hilcorp proposes to begin facilities work this August with work expected to last until next February, with 75 days of facility construction expected and drilling operations to follow.

The facility infrastructure will support gas production from the Seaview 8, 9 and 10 wells.

The company said bringing the Seaview Pad online will involve installing gas production facilities on the existing pad and building a gas pipeline from the pad to tie into the existing Enstar gas transmission pipeline.

Seaview will not be a manned facility but will be monitored by personnel staged out of the Ninilchik unit Susan Dionne pad control room.

Proposed infrastructure includes up to three heater separator unit skids, two compressor skids, two dehydration units, a vent stack with a vent scrubber for venting gas when needed, control room, microturbine building, two 200-barrel double-walled produced water tanks and a meter building.
