The top 19 oil and gas operators in Ellis County, Oklahoma, ranked by monthly oil production. Combined output of all 25 reporting operators: 958,335 BBL oil and 9,840,653 Mcf gas across 1,104 reporting wells/leases.
Momentum blends the year-over-year change in average monthly production (oil + gas at 6 Mcf per BOE, 2025-09 – 2026-02 vs the same months a year earlier, complete reporting months only) with the change in drilling permits (last 12 months vs the prior 12: 4 vs 26). Each input is capped at ±100%.
Benchmark gross value of production: about $63.2M per month — 608,330 bbl of oil and 5,924,490 Mcf of gas a month, priced at the EIA average WTI ($61.19/bbl) and Henry Hub ($4.22/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.
