Production
- filling in (est. · provisional) . Hatching marks our estimate of the volume still to be filed. That estimate draws on our own production forecast. This estimate is published as our best figure. No miss stands against it. It updates as filings arrive
- estimated . Hatching marks our estimate. In the most recent months that is volume still to be filed. Past the divider it is our estimate of each whole month, built on any filings already in. Beyond the last filings it is our forecast.
In this view, hatching marks our estimate, and in the most recent months that is volume still to be filed. Past the divider, the chart continues only the bands it has drawn. Each band continues as our estimate, from any filings already in and then from our forecast, built by summing our per-well forecasts. The method behind each well is recorded with the forecast. The forward months cover existing wells only. How our methods work
All from what the source published. All held at well grain.
How the volume breaks down
- 34.0% Reported by the official source by well
- 66.0% 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.
Every barrel through May 2026 starts from what the official source published for those months. Measured over January 1993 to May 2026.

About this chart
The stack shows what is holding today's rate up and how much of it is new drilling. In the reported months the bands draw the filings already in. The months still filling in are marked.
Texas reports production two ways: for an oil lease or unit, and for an individual gas well. A figure reported for a lease or unit is divided among the wells it covers, and every Texas barrel is labeled reported or allocated. How well-level Texas production is built

About this map
Undetermined means not enough signal to settle it. Producing wells are the ones that reported oil or gas in the 12 months to Aug 2026.
Type curves
best estimate incl. allocated
Horizontal wells only. Average production per well, for wells grouped by when they first produced.
How these curves are built
Horizontal wells only: 2,586 of the 2,709 wells in these cohorts. Average daily production per well, for wells grouped by when they first produced. Includes every well of the cohort that is old enough at each month. Wells that are shut in or have stopped producing count as zero, so the average reflects the full cohort, not just survivors. Rates are calendar-day (volume ÷ days in month). The cumulative axis accumulates those same monthly averages at the average month length. Months not yet fully reported are excluded. The 2010-2014 curve draws those years as one group. The chart opens on average daily rate against months on production, the rate on a log scale. The view control switches to rate against cumulative production per well, on the same log rate scale, or to cumulative production per well against months on production, on a linear scale. Every view draws the same cohorts from the same production history. Each cohort is solid through the last month all the wells in its curve sit inside fully reported data. Past it the dashed curve carries the same wells forward, on our forecast where a well’s own record ends, for up to five years. A dashed curve runs as far as at least nine in ten of its wells are accounted for. A well that is old enough but shut in still counts, as zero. The measured months are what these wells reported. In the forward months each well counts its own reported figure for each month it has one, our forecast for each month it has only that, and zero for the rest. The forward average counts every well in the curve. The drawn forecast runs up to five years past the measured months. Line thickness tracks the size of each cohort. 2 wells are counted here but not shown on the age axis: they started producing in 1995 or earlier, too close to the start of our records for their region to verify their true age.

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 |
|---|---|---|---|
| Texas production | well | 1993-01 | ~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 official records as they arrive. Recent months can differ without either being wrong; the methodology page explains both methods.
Coverage rows for McMullen County, Texas are regenerated at every build from the same catalog of sources the data is built from.
