Short answer
ConocoPhillips is Alaska's largest crude oil producer, by its own 2025 10-K, and operates the Greater Kuparuk Area and the Western North Slope; Hilcorp operates the Greater Prudhoe Area. Other large state leaseholders include Oil Search (Alaska), Repsol, ExxonMobil, APA and Great Bear Petroleum. Alaska produced 422,000 barrels of crude a day in 2025, fifth among states (EIA). Census County Business Patterns counted 79 oil and gas establishments in 2023, 43 of them support contractors.
- ConocoPhillips reported 199,000 barrels of oil equivalent a day of net Alaska production in 2025.
- ConocoPhillips Alaska holds 387,828 acres of state leases, the most of any lessee, as of 7 October 2026.
- Alaska's 43 support-activity establishments employ 3,767 people at average pay of $109,128.
- The Alaska Oil and Gas Association lists 14 member companies.
- ConocoPhillips expects first oil from Willow in early 2029, a multi-year construction program on the North Slope.

Who runs Alaska's oil fields
ConocoPhillips' 2025 10-K says it is "the largest crude oil producer in Alaska" and gives its net production by field area and the operator of each:
| Field area | Operator | ConocoPhillips interest | ConocoPhillips net production, 2025 (barrels of oil equivalent a day) |
|---|---|---|---|
| Greater Prudhoe Area | Hilcorp | 36.5% | 85,000 |
| Greater Kuparuk Area | ConocoPhillips | 94.2% to 99.8% | 75,000 |
| Western North Slope | ConocoPhillips | 100.0% | 39,000 |
| Total Alaska | 199,000 |
The same filing says ConocoPhillips owns 29.5% of the Trans-Alaska Pipeline System, ships its North Slope oil from Valdez on five company-owned tankers, and expects first oil from the Willow project, in the Western North Slope's Bear Tooth Unit, in early 2029, with the processing facility due to be shipped to the North Slope in 2027. Alaska contributed $5.64 billion of the company's 2025 sales and other operating revenues.
The largest leaseholders on state land
The Alaska Division of Oil and Gas publishes the acreage of state leases held by each lessee. As of 7 October 2026:
| Lessee (as listed) | State lease acreage |
|---|---|
| ConocoPhillips Alaska, Inc. | 387,828 |
| Oil Search (Alaska), LLC | 353,180 |
| Repsol E&P USA, LLC | 282,530 |
| Hilcorp Cook Inlet, LLC | 232,365 |
| Great Bear Petroleum Ventures II, LLC | 230,689 |
| ExxonMobil Alaska Production, Inc. | 174,819 |
| Hilcorp Alaska North Slope, LLC | 165,969 |
| APA Alaska, LLC | 162,706 |
| Lagniappe Alaska, LLC | 138,467 |
| Hilcorp North Slope, LLC | 113,567 |
The report covers 3,302,901 acres in all, 2,345,783 onshore and 957,118 offshore. ConocoPhillips holds another 101,029 acres through ConocoPhillips Alaska II, and Hilcorp's three entities together hold 511,901. The report covers leases on state land; federal leases, such as those in the National Petroleum Reserve, aren't included.
Production
The US Energy Information Administration (EIA) puts Alaska's 2025 crude output at 422,000 barrels a day, fifth among states, down from 448,000 in 2020; the North Slope supplied 414,000 and South Alaska 8,000. Alaska's marketed natural gas was 368,956 million cubic feet in 2025. The Division of Oil and Gas reports 14.158 million barrels of oil produced in August 2026 on its royalty data page.
Alaska in Census data
US Census Bureau County Business Patterns (CBP) 2023, State of Alaska, NAICS 211 (Oil and Gas Extraction), 213111 (Drilling Oil and Gas Wells), 213112 (Support Activities for Oil and Gas Operations) and 324110 (Petroleum Refineries):
| Measure (2023) | Alaska |
|---|---|
| Establishments | 79 |
| Employees, payroll and average pay | Not reported (high-noise figure) |
| Share of US establishments | 0.47% of 16,710 |
| Rank among states | 21st |
The Census Bureau published the statewide employee and payroll totals but flagged them as high-noise: the noise it adds for confidentiality changed them by 5% or more, so we don't report them. It doesn't publish the size split. The segment rows:
| Segment (NAICS) | Establishments | Employees | Average annual pay |
|---|---|---|---|
| Support activities (213112) | 43 | 3,767 | $109,128 |
| Crude petroleum extraction (211120) | 17 | Not reported | Not reported |
| Drilling (213111) | 11 | Not reported | Not reported |
| Natural gas extraction (211130) | 4 | Not reported | Not reported |
| Petroleum refineries (324110) | 4 | 622 | $204,723 |
By borough, Anchorage has 36 establishments, the North Slope Borough 12 and the Kenai Peninsula Borough 11 (444 employees); 4 more are recorded statewide. Anchorage's employee total is flagged high-noise. These counts are establishments with paid employees, not companies, and the self-employed aren't included. At 79 establishments, the Census count is a floor: the field camps and contractors behind it are better counted company by company.
EIA lists Alaska's refineries as of 1 January 2026: Tesoro Alaska at Kenai (68,000 barrels a day), Petro Star at Valdez (62,500) and North Pole (25,000), and two North Slope plants at Prudhoe Bay run by ConocoPhillips (15,000) and Hilcorp (6,500), 177,000 in all.
No listed head offices
No SEC-registered listed company in the oil and gas industry codes has its business address in Alaska. The operators are Alaska subsidiaries of companies headquartered elsewhere, run from Anchorage offices, so each account has a local team and a head office with its own supplier rules.

Selling to Alaska oil and gas companies
With so few operators, every account matters and procurement is formal: expect contractor prequalification, safety reviews and long contracts. The field work is seasonal and remote, so vendors who already have North Slope logistics and safety approvals have an edge.
Illustrative example. The seller and its prices are invented; the company list is from the sources above.
Ptarmigan Medical (ptarmigan.example) provides paramedics and telemedicine for remote work camps. Its list is short: the AOGA's 14 members plus the larger lessees not on that list, about 20 companies. Two contacts at each (the HSE director and the logistics or camp services manager) is 40 people. At a 10% reply rate, 4 conversations; one contract for two medics on a winter project at $450,000 a season pays for a year of selling. A market this small rewards research per account, which is where Bebop helps; the account research guide covers what to look for.
Next step: compare Alaska's operators with the largest producers in the country in the list of the largest oil and gas companies.
