The top 16 oil and gas operators in Duval County, Texas, ranked by monthly oil production. Combined output of all 25 reporting operators: 3,148,274 BBL oil and 89,916 Mcf gas across 183 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: 9 vs 3). Each input is capped at ±100%.
Benchmark gross value of production: about $4.3M per month — 40,987 bbl of oil and 310,912 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.
