Short answer
The largest oil and gas companies headquartered in Tulsa by 2025 revenue are ONEOK ($33.63 billion) and Williams ($11.95 billion), both midstream, followed by drilling contractor Helmerich & Payne ($3.75 billion) and NGL Energy Partners ($3.16 billion), from their 10-Ks. Census County Business Patterns counted 361 oil and gas establishments in the Tulsa metro in 2023, with 3,869 employees. Operators with Tulsa addresses run 10,261 active Oklahoma wells, by Corporation Commission records.
- ONEOK's $33.63 billion of 2025 revenue is more than every other Tulsa oil and gas company's combined.
- The metro's 361 oil and gas establishments average just 10.7 employees; 227 have fewer than five.
- 179 operators with an open Corporation Commission status have Tulsa addresses, second only to Oklahoma City.
- Creek County, in the metro, has 6,605 active wells, 4,888 of them oil, spread across 331 operators.
- Osage County's oil is leased through the Bureau of Indian Affairs, not the state, under 25 CFR part 226.

This report is for people looking for an oil and gas employer or partner in Tulsa, suppliers and contractors who want the city's energy companies as customers, and B2B sellers planning a northeast Oklahoma territory.
Tulsa's public energy companies
The Tulsa City-County Library's oil history timeline records that by 1930 "more than 800 oil companies have headquarters in Tulsa." Today's largest are midstream. SEC-registered companies in oil and gas whose latest 10-K gives a Tulsa head office:
| Company | Business | Revenue, latest fiscal year (10-K) |
|---|---|---|
| ONEOK | Midstream: natural gas liquids, gathering and processing, gas pipelines, refined products and crude | $33.63 billion (2025, up from $21.70 billion) |
| Williams Companies | Natural gas transmission, gathering and processing | $11.95 billion (2025) |
| Helmerich & Payne | Drilling rigs, mainly in Texas, plus the Middle East and Latin America | $3.75 billion (year to September 2025) |
| NGL Energy Partners | Water solutions, crude oil logistics and liquids logistics | $3.16 billion (year to March 2026) |
| Empire Petroleum | Exploration and production | $34.2 million (2025) |
Circle Energy, also based in Tulsa, reported no revenue for 2025. Part of ONEOK's jump in revenue came from the EnLink acquisition, which its 10-K says it completed on 31 January 2025. These head offices buy like large corporations: through supplier registration, category managers and multi-year contracts.
Tulsa in Census data
US Census Bureau County Business Patterns (CBP) 2023, Tulsa, OK Metro Area (CBSA 46140), NAICS 211, 213111, 213112 and 324110:
| Measure (2023) | Tulsa metro |
|---|---|
| Establishments | 361 |
| Employees (week of March 12) | 3,869 |
| Annual payroll | $477,049,000 |
| Average employees per establishment | 10.7 |
| Average annual pay | $123,300 |
| Share of US establishments | 2.16% of 16,710 |
| Segment (NAICS) | Establishments | Employees | Average annual pay |
|---|---|---|---|
| Crude petroleum extraction (211120) | 197 | 1,390 | $145,463 |
| Support activities (213112) | 117 | 1,231 | $129,714 |
| Natural gas extraction (211130) | 24 | 586 | $115,522 |
| Drilling (213111) | 23 | 662 | $71,725 |
By size, 227 establishments have 1 to 4 employees and 63 have 5 to 9; the Census Bureau doesn't publish the larger classes for the four codes combined.
| County | Establishments | Employees |
|---|---|---|
| Tulsa County | 228 | 3,135 |
| Creek County | 49 | Not reported |
| Osage County | 34 | 234 |
| Pawnee County | 20 | 137 |
| Okmulgee County | 18 | Not reported |
| Rogers County | 5 | Not reported |
"Not reported" marks a total the Census Bureau flagged as high-noise (its confidentiality noise moved the value by 5% or more). These figures leave out much of what makes Tulsa an energy city. Pipelines have their own code (NAICS 486), with 25 establishments in the metro, and head offices are often filed under management of companies (NAICS 55). And although the US Energy Information Administration lists HF Sinclair's Tulsa East (70,300 barrels a day) and Tulsa West (85,000) refineries as of 1 January 2026, no petroleum refinery establishment appears in the metro's CBP figures, so use EIA for refining. The counts are establishments with paid employees, not companies, and exclude the self-employed.
The operators with Tulsa addresses
The Oklahoma Corporation Commission (OCC) operator list has 179 operators with an open surety status and a Tulsa office address, second to Oklahoma City's 265. In the OCC's nightly well file, 173 Tulsa operators run 10,261 active wells, 7.9% of the state's 129,147.
| Operator (as the OCC names it) | Active wells in Oklahoma |
|---|---|
| Abundance Energy Services LLC | 1,580 |
| Twain Energy LLC | 627 |
| Unit Petroleum Company | 554 |
| Rocky Roads Operating LLC | 524 |
| FBF Energy LLC | 463 |
| Staghorn Petroleum II LLC | 450 |
| New Dominion LLC | 383 |
| Chisholm Oil and Gas Operating LLC | 352 |
| Kaiser-Francis Oil Company | 256 |
Tulsa operators also filed 86 of the state's 647 new-drill permits from January to 29 October 2026. The most active were Anthem Energy Operating (Oklahoma) with 12, Nadel and Gussman with 11, Citizen Energy Ventures with 10, and Sanguine Gas Exploration and Culbreath Oil & Gas with 9 each. An OCC address is where an operator receives mail, which isn't always its head office.
The old fields around the city
The metro's wells are mostly small and old. Creek County has 6,605 active wells in the OCC file (4,888 oil) run by 331 operators; Okmulgee has 3,757, Tulsa County 1,610, Pawnee 1,469 and Rogers 1,083. New drilling is rare: Creek drew 21 new-drill permits in 2026 and the other metro counties two or fewer. The library's timeline dates the Red Fork discovery, four miles west of Tulsa, to June 1901 and the Glenn Pool's Ida Glenn well to November 1905.
Osage County is different. The OCC file shows no active wells there because the Bureau of Indian Affairs' Osage Agency administers leasing and development of the 1.45 million-acre Osage Mineral Estate, under federal regulations at 25 CFR part 226. Operators there file with the Agency, including its Form 139 for well operations.

Selling to Tulsa oil and gas companies
| Account type | Examples | Who usually decides |
|---|---|---|
| Midstream head offices | ONEOK, Williams, NGL Energy Partners | Category managers in supply chain; asset and integrity teams set specs |
| Drilling contractor | Helmerich & Payne | Procurement and engineering at head office; rig managers in the field |
| Small and mid-size operators | The OCC's 173 Tulsa operators with active wells | Owner, operations manager or contract pumper |
| Refineries | HF Sinclair's two Tulsa plants | Maintenance, reliability and turnaround planners |
Illustrative example. The seller and its prices are invented; the well and operator counts are OCC data.
Turkey Mountain Pump (turkeymountain.example) repairs rod pumps and rebuilds pumping units. Creek County has 331 operators with active wells, but only 31 run 50 or more; those 31 hold 3,511 wells. The shop calls the owner or operations manager at each: 31 people. At a 12% reply rate that's about 4 conversations; if two sign up for repairs on a quarter of their wells a year at $1,800 each, that's roughly 50 wells and $90,000. Small operators rarely have a procurement team, so the first call reaches the person who decides. Bebop can find operators that match and research each one; see how to sell to small businesses for the approach.

Questions people ask
What oil and gas companies are headquartered in Tulsa?
Public companies whose latest 10-K gives a Tulsa head office include ONEOK ($33.63 billion in 2025 revenue), Williams ($11.95 billion), Helmerich & Payne ($3.75 billion for the year to September 2025), NGL Energy Partners ($3.16 billion for the year to March 2026) and Empire Petroleum. Other operators with Tulsa addresses in Corporation Commission records include Kaiser-Francis Oil, Unit Petroleum, New Dominion and Staghorn Petroleum II.
How many oil and gas companies are in Tulsa?
Census County Business Patterns counted 361 oil and gas establishments in the Tulsa metro in 2023, with 3,869 employees; 228 were in Tulsa County. The Oklahoma Corporation Commission's operator list shows 179 operators with an open status and a Tulsa address in October 2026. Pipeline companies and many head offices are counted under other Census codes.
Why is Tulsa called the Oil Capital of the World?
Tulsa grew with the oil discoveries around it: the Tulsa City-County Library's timeline dates oil at Red Fork, four miles west of the city, to 1901 and the Glenn Pool's Ida Glenn well to 1905, and records that more than 800 oil companies had headquarters in Tulsa by 1930. Today its largest energy companies, ONEOK and Williams, are pipeline and processing businesses.
Are there oil refineries in Tulsa?
Yes. The US Energy Information Administration lists two HF Sinclair refineries in Tulsa as of 1 January 2026: Tulsa West, with 85,000 barrels a day of operating capacity, and Tulsa East, with 70,300. Together they hold 155,300 of Oklahoma's 543,800 barrels a day. Census County Business Patterns doesn't show a refinery establishment in the Tulsa metro, so use EIA figures for refining.
Who regulates oil wells in Osage County, Oklahoma?
The Bureau of Indian Affairs' Osage Agency administers leasing and development of the 1.45 million-acre Osage Mineral Estate, under federal regulations at 25 CFR part 226. That is why the Oklahoma Corporation Commission's well file shows no active wells in Osage County. Operators file with the Agency, including its Form 139 for well operations and reports.
