Simplify's Take

What believers are saying

  • Hilcorp won the August 2026 Put 29 permitting process for North Slope gravel.
  • Hilcorp secured Alaska lease interest after the 2026 offshore sale attracted only one bid.
  • Hilcorp's 2026 Cook Inlet drilling still supports Enstar and Southcentral winter supply.

What critics are saying

  • PHMSA's March 2026 North Fork Pipeline case remains open, signaling compliance strain.
  • Cook Inlet gas shortage worsens through 2029 if Hilcorp cannot add supply.
  • Hilcorp's 2026 Alaska gravel mine and wetland permits invite delays, litigation, and reputational damage.

What makes Hilcorp unique

  • Hilcorp monetizes mature fields others exit, like BP Alaska in 2020.
  • Hilcorp controls Alaska infrastructure, including Prudhoe Bay and Cook Inlet operations.
  • Hilcorp keeps production alive by drilling relentlessly, not chasing frontier exploration.

South Korea takes steps toward potential Alaska LNG investment.

South Korea takes steps toward potential Alaska LNG investment. The South Korean government has agreed to continue working with the United States government on a potential investment in the Alaska LNG project by the major gas-importing country, as part of their trade deal. President Donald Trump said on his Truth social media platform on Wednesday the two countries "agreed to commence working together on the 50 Billion Dollar ALASKA LNG PROJECT". Lead developer Glenfarne Group LLC pegged the South Korean investment at over $50 billion. Seoul, however, has not announced a definitive figure. "The United States and Korea have agreed to commence working on the Alaska LNG project, subject to meeting commercial reasonableness under the Strategic Investment MOU and all applicable domestic legal requirements", said a statement posted on the U.S. Commerce Department's website, referring to a broader 2025 agreement for South Korean investment in U.S. energy projects. "In developing the project, the United States will facilitate the favorable involvement of Korean vendors and suppliers. The United States intends to provide assurances, to the extent possible, regarding offtake agreements at economically viable prices granting Korea priority access to Alaska LNG produced by this project". South Korean President Lee Jae-myung said on X, as translated from Korean, "Regarding the Alaska LNG project among the investment projects announced by the U.S., it was decided to commence working on the preconditions that 1) commercial viability is confirmed and 2) it complies with South Korean legal procedures". Alaska LNG holds an Energy Department permit to export 20 million metric tons per annum of LNG, or 2.55 billion cubic feet a day of natural gas equivalent according to Alaska LNG, to both FTA and non-FTA countries. The project secured authorization November 2014 for the portion for countries with a free trade agreement (FTA) with the U.S. and August 2020 for the non-FTA portion. On December 11, 2025 the Federal Permitting Improvement Steering Council announced the completion of permit renewal for the project, which would process gas from the North Slope for both the domestic and overseas markets, following a review of environmental opinions. New York City-based Glenfarne said in a press release Wednesday it will "work with the U.S. and Korean governments to finalize the investment structure and complete the remaining steps required to reach FID". "Today's announcement brings together the capital needed to accelerate Alaska LNG to a final investment decision and construction", said Glenfarne chief executive and founder Brendan Duval. Alaska LNG is planned to proceed in two phases. The first phase would supply gas to the domestic market via a pipeline to the Anchorage region. Earlier this year ConocoPhillips signed a long-term deal to supply gas produced on Alaska's North Slope to the state under phase 1 of Alaska LNG. With the 30-year "gas sales precedent agreement" with Houston, Texas-based ConocoPhillips, "Alaska LNG has now secured precedent agreements for sufficient volumes to support a Phase One final investment decision and supply enough natural gas to meet Alaska's energy needs", Glenfarne announced May 18. "Alaska LNG now has agreements with all three major North Slope producers: ConocoPhillips, ExxonMobil (NYSE: XOM), Hilcorp Alaska, as well as Great Bear Pantheon LLC, a wholly owned subsidiary of Pantheon Resources plc (AIM: PANR)", Glenfarne added. Glenfarne previously said it aims to mechanically complete the 739-mile, 42-inch pipeline 2028 and start gas delivery 2029. Alaska LNG's phase 1 would "strengthen long-term energy security and address looming supply shortfalls resulting from declining Cook Inlet production", Glenfarne said, announcing the agreement with ConocoPhillips. "Phase 2 will add the LNG export facilities in Nikiski", Glenfarne added. For the overseas portion of Alaska LNG's production, Glenfarne has announced preliminary long-term agreements with Taiwan's state-owned CPC Corp, Japan's JERA Co Inc and Tokyo Gas Co Ltd, South Korea's POSCO International Corp, Thailand's state-owned PTT Exploration and Production Public Co Ltd and France's TotalEnergies SE. Announcing the latest offtake agreement February 26, 2026, Glenfarne said it "intends to contract 80 percent, or 16 MTPA [million metric tons per annum], of Alaska LNG's 20 MTPA volume to finance the project and now has 13 MTPA accounted for under preliminary long-term agreements with TotalEnergies, JERA, Tokyo Gas, CPC, PTT and POSCO". At the end of 2025 Sydney, Australia-based Worley Ltd completed "engineering work sufficient for a final investment decision", Glenfarne said January 22, 2026. The January announcement also said Glenfarne has provisionally selected Worley for engineering, procurement and construction management services for Alaska LNG. The update also announced conditional awards for pipe supply and construction. On November 10, 2025 Glenfarne said it had contracted Baker Hughes to supply refrigerant compressors and power generation equipment for Alaska LNG. Baker Hughes has also committed to investing in Alaska LNG. Glenfarne took over Alaska LNG last year as lead developer. The state government's Alaska Gasline Development Corp retains 25 percent.

The North Trading Bay sheen reinforces the need to dismantle retired oil & gas infrastructure.

The North Trading Bay sheen reinforces the need to dismantle retired oil & gas infrastructure. This is one more reminder of why having oil and gas in its backyard is a liability to the marine ecosystems Inletkeeper rely on for its livelihoods and wellbeing. Enough is enough. Inletkeeper has to start holding oil & gas operators in Cook Inlet accountable for dismantling retired infrastructure. FOR IMMEDIATE RELEASE: 8/25/2026 MORE INFORMATION: Satchel Pondolfino, Clean Water Lead, 907-235-4068 x26 The North Trading Bay sheen reinforces the need to dismantle retired infrastructure. HOMER, AK - Cook Inletkeeper calls for the relevant authorities to continue investigating the source and cause of the sheen observed in the North Trading Bay area on August 24. This incident shows the risk of allowing half-century-old oil and gas infrastructure to remain standing indefinitely in its waters. Hilcorp's Spark platform, installed in 1967 and inactive since 1992, has been identified as a probable source of the unknown pollutant. This warrants that state agencies conduct a thorough inspection of the Spark platform, its neighbors, and associated pipelines. This should include the integrity of all shut-in wells in the vicinity, if those wells cannot be ruled out as a source of the sheen. Cook Inletkeeper applauds the citizen pilot who alerted officials to the oil sheen stretching five miles across Cook Inlet. "This is one more reminder of why having oil and gas in our backyard is a liability to the marine ecosystems we rely on for our livelihoods and wellbeing," said Satchel Pondolfino, Inletkeeper's Clean Water Lead. "Enough is enough; we have to start holding operators accountable for dismantling retired infrastructure. Hilcorp, the owner of the Spark platform and 15 of the 17 in Cook Inlet, has a well-documented business model of buying old equipment and cutting corners to increase production - a business practice that has resulted in an egregious track record of environmental and safety violations. Though the official source is still in question, this week's spill is another example of the threat aging infrastructure poses to Cook Inlet's fish, wildlife, and coastal communities, and of the need for owners to take responsibility." The State of Alaska has every authority to enforce the dismantling, removal, and remediation of old platforms but has never once required an oil and gas operator to do so, despite the risks, maintenance needs, and the fact that cleanup costs increase significantly the longer they remain inactive. Yesterday's spill is just the latest warning. As Hilcorp's abandoned infrastructure continues to rot, more leaks and spills are inevitable. These disasters are not accidents - they are the direct result of neglect and entirely preventable. Dismantlement has been delayed long enough. "Hilcorp enjoys a free pass in Cook Inlet. While most oil and gas companies pay their fair share, Hilcorp dodges state corporate income tax entirely. They get a Clean Water Act exemption, dumping toxic drilling muds and polluted water straight into Tikahtnu. To top it off, state regulators keep letting Hilcorp put off cleaning up their old, dangerous infrastructure, leaving Alaskans to shoulder the risk," said Bridget Maryott, Inletkeeper's Co-Executive Director. This spill comes at a time when Cook Inlet is slated for extensive lease sales in the federal waters of the lower inlet. The One Big Beautiful Bill Act (OBBBA) mandated six new offshore oil and gas lease sales in Cook Inlet, through 2032. While the first of these lease sales, held on March 4, 2026, raised $0 and drew no bids, the Trump administration is proposing five additional lease sales in the Inlet, in addition to the five mandated by the OBBBA, as part of its proposed offshore drilling leasing schedule. Continuing to build out oil and gas infrastructure in Cook Inlet amplifies the risk of leaks, spills, and continued toxic dumping. About Cook Inletkeeper: Cook Inletkeeper is a community-based non-profit organization that advocates for clean water and lands for all, protecting Alaska's Cook Inlet | Tikahtnu watershed and the life it sustains.

Hilcorp seeks federal permit for new North Slope gravel mine; comment closes Aug. 18.

Hilcorp seeks federal permit for new North Slope gravel mine; comment closes Aug. 18. Hilcorp Alaska wants to open a new gravel mine in the Putuligayuk River area of the North Slope. The public has until Aug. 18 to weigh in. The U.S. Army Corps of Engineers Alaska District published the permit notice on Aug. 3. It describes a new mine site called Put 29 and an access road about 1,000 feet long and 36 feet wide at the surface. The road would leave an established gravel road that serves Drillsite 15. The plan is dated May 2026. Kristen Hoppe of Hilcorp Alaska is listed as the applicant contact. The notice says the purpose is to develop a new gravel source and access road, which is "necessary for continued oil and gas development, as current gravel sources are being depleted throughout the North Slope." The notice does not state how many acres of wetlands or tundra the mine and road would disturb. It quantifies neither the wetland impact nor any effect on subsistence resources. Conservation-oriented reviewers who have commented on other North Slope gravel filings contend such projects can cause uncompensated wetland loss and warrant stronger mitigation. The notice includes no response from North Slope subsistence users, tribal organizations, or local government about this proposal. It presents only the applicant's account. North Slope oilfield roads, pads, and related infrastructure are built on gravel. Alaska News has covered a series of similar filings this summer, including two ConocoPhillips gravel expansions in the Kuparuk River Unit that were open for comment through late July. Hilcorp became operator of major North Slope fields in 2020, when state agencies approved the transfer of BP's upstream Alaska assets and the formation of Hilcorp North Slope, LLC. In a 2024 state water quality filing for Phase II of its Ugnu Mine Site E, Hilcorp reported 24.2 acres of new wetland impact, for a Phase I and II total of 50.5 acres. The company proposed that no compensatory mitigation was required because the impacts were temporary and minimal. The permit is not approved. Written comments go to Andrew Kastning, the Corps regulatory project manager, at [email protected]. The filing is listed as POA-2026-00362.
