Oil & Gas Exploration & Production covers the companies that find and produce crude oil and natural gas, along with mineral and royalty owners. MoatScope covers 87 companies here. One has a wide moat, 15 a narrow moat and 71 none.

How the industry makes money

Producers are price takers: profit is the oil or gas price minus the cost of drilling and operating wells. Wells decline quickly, so producers must keep reinvesting just to hold output steady, and the quality of their acreage decides how much each dollar of drilling returns.

Where the moats are

All 16 moat-rated companies have a cost advantage, usually low-cost acreage in the best parts of the best basins. Efficient scale appears in six.

  • Texas Pacific Land: roughly 870,000 acres of surface and royalty land in West Texas, a perpetual asset that earns royalties and land fees without the cost of drilling.

The narrow-moat group includes ConocoPhillips, EOG Resources, Occidental, Diamondback, EQT, Expand Energy and Permian Resources, producers with deep inventories of low-cost wells. Most producers, including large ones such as Canadian Natural Resources, Woodside and Devon, carry no moat.

What wears moats down

Commodity prices set the industry's fortunes, and even the best acreage runs out. Service costs rise in booms, and policy shifts on drilling, emissions and exports can change the economics of whole regions.

What the quality scores say

Texas Pacific Land scores 76 on MoatScope's quality scale and EOG Resources 65, against an industry average of 34.

What to watch

  • Oil and natural gas prices.
  • Drilling inventory depth and cost per barrel.
  • Capital discipline and shareholder returns across the cycle.

Markets

MoatScope splits Oil & Gas Exploration & Production into 3 markets. Each table ranks the businesses in one market by revenue and shows each one's share of the market's total: companies filed under this industry, the segments of companies filed elsewhere that compete in it, and the largest companies MoatScope doesn't cover, such as private companies and companies listed outside the US. Each market's total comes from a cited source and covers the geography its businesses compete in (a national market counts only US revenue). A company that runs several businesses is split by the segments it reports.

Market share is a company's revenue in its main market (Market column) as a share of that market's total: every company in it, including private companies and companies listed outside the US (sources under each market above). Revenue is for the fiscal year closest to 2025, and a market that is national (such as US banking) counts only US revenue. Companies that run several businesses are split by the segments they report, and each segment counts in its own market. A dash means the market has no reliable total yet, or no revenue was reported for that year.

Price versus fair value for every company is in the screener.
