East Texas Oilfield Operators List — 2026

Active operators on the East Texas Oilfield — long-tenured private waterflood operators, stripper-well operators, and the limited modern horizontal exploration of the underlying Eagle Ford Shale.

Quick answer

East Texas Oilfield operators are predominantly long-tenured private waterflood operators (Crawford Oil & Gas, Texas Petroleum Investment Company, Hilcorp Energy, Riley Exploration Permian, plus many smaller private operators). Stripper-well operators work field-edge wells. Limited horizontal Eagle Ford Shale activity in some sections. The field is a stable mature producer with concentrated, decades-tenured operator relationships.

How to Use This List

The East Texas Oilfield's operator base is unusually concentrated and stable — long-tenured private operators have been running waterflood units across the field for decades. The valuation framework for an East Texas Oilfield interest depends on the specific waterflood unit and operator working your acreage. If you've received an offer or your division order shows an unfamiliar operator, request a free written second opinion.

Major Waterflood Unit Operators

Long-tenured private operators running East Texas Oilfield waterflood units:

Crawford Oil & Gas — long-tenured East Texas Oilfield waterflood operator

Texas Petroleum Investment Company — multiple East Texas waterflood positions

Hilcorp Energy — selected East Texas Oilfield positions; large mature-asset focused operator

Riley Exploration Permian — selected East Texas mature waterflood positions

Multiple long-tenured private operators — many waterflood units have been run by the same operator (or operator family) for 30-50+ years

Stripper-Well Operators

Hundreds of small private operators work stripper wells around the East Texas Oilfield's edges and in legacy positions inside the field. Stripper wells produce small but predictable royalty checks for many decades. If you've been receiving small monthly checks from an operator you don't recognize, the well is likely a stripper.

Modern Horizontal Eagle Ford Activity

The Eagle Ford Shale sits stratigraphically below the Woodbine Sandstone across portions of the East Texas Oilfield region. Limited horizontal Eagle Ford activity has occurred in some sections, particularly to the south and west of the historic field. The Eagle Ford in East Texas is a separate play from the Eagle Ford of south Texas — different operator profile, different production characteristics.

If You Receive an Offer From an East Texas Oilfield Operator

The East Texas Oilfield's long, predictable waterflood production tail makes it relatively easy to value mineral interests on the field — but the actual valuation depends heavily on the specific waterflood unit's expected remaining reserve life, the operator's maintenance investment, and any depth-specific lease terms (Woodbine only? or also covers underlying Eagle Ford?). Request a free written second opinion to confirm the offer reflects the full waterflood tail value.
