Know what the ground under you produced
Lease production, operator filings, well records and pipeline permits — every public Texas oil and gas record, in one place, as one page per thing.
Free to search. No account. Every figure is a state filing.
Every lease has a page: the monthly barrels and Mcf the operator reported, the wells drilled on it, and what each month was worth at the benchmark price.
Every figure comes from a Railroad Commission filing, priced with published EIA benchmarks. Nothing is modelled or estimated; where the state has no data, the page says so rather than guessing.
The lease, operator and county pages are static HTML that anyone — and any AI assistant — can read and cite, with the filing behind every figure named on the page.
