The top 11 oil and gas operators in Jefferson County, Texas, ranked by monthly oil production. Combined output of all 25 reporting operators: 1,432,904 BBL oil and 467,417 Mcf gas across 90 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: 21 vs 13). Each input is capped at ±100%.
Benchmark gross value of production: about $2.9M per month — 30,817 bbl of oil and 143,748 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.
