The top 9 oil and gas operators in San Augustine County, Texas, ranked by monthly oil production. Combined output of all 11 reporting operators: 3,049 BBL oil and 64,329,016 Mcf gas across 423 reporting wells/leases.
Momentum blends the year-over-year change in average monthly production (oil + gas at 6 Mcf per BOE, 2025-11 – 2026-05 vs the same months a year earlier, complete reporting months only) with the change in drilling permits (last 12 months vs the prior 12: 108 vs 36). Each input is capped at ±100%.
Benchmark gross value of production: about $110.0M per month — 1,187 bbl of oil and 25,229,504 Mcf of gas a month, priced at the EIA average WTI ($73.03/bbl) and Henry Hub ($4.20/MMBtu) spot prices over the same months.
Benchmark prices before quality and location differentials, transport, taxes and costs; this is a county-level economic indicator, not the value of any mineral or royalty interest.
