Production
All from what the source published. All held at well grain.
How the volume breaks down
- 98.5% Reported by the official source by well
- 1.5% Reported by the official source as a lease total, split across the lease's wells. The regional total shown is the reported number, to rounding.
- 0.01% A series adjusted so a total meets a published figure: a well's own cumulative from the official source, or a state's yearly total from a second official source.
Every barrel here starts from what the official source published for the months measured. Measured over January 1984 to February 2026.

About this chart
The stack shows what is holding today's rate up and how much of it is new drilling. The bands draw the filings already in.
These volumes are the production from the wells and facilities this company operates. Ownership works differently: other parties hold interests in these wells, and this company holds interests in wells that other companies operate. How we attribute production to a company

What we cover here
Each row names the grain a region’s production is held at. Where a source publishes at a coarser grain, the page says so.
| Data | Grain | Since | Benchmark |
|---|---|---|---|
| Gulf of Mexico production | well | 1947-11 | ~100% of EIA |
| Louisiana production | well | 1977-01 | ~97–98% of EIA |
| Mississippi production | well | 1946-07 | ~100–102% of EIA |
| Texas production | well | 1993-01 | ~99–100% of EIA |
Benchmark cells compare our series with the EIA’s published estimates.
About the EIA comparison
The two are produced differently: the EIA estimates from a survey of the largest operators and a model built to anticipate late filings, while the series compared here are rebuilt from the source’s own records as they arrive. Recent months can differ without either being wrong; the methodology page explains both methods.
Coverage rows for LLOG Exploration are regenerated at every build from the same catalog of sources the data is built from.
Top regions by 2025 operated production
