The Duffer "A" Unit is a small, long-life waterflood unit in the Adams field area of Eastland County. As on many small units, a handful of wellbores can carry most of the unit’s production, so owners benefit from understanding how the unit agreement allocates revenue across tracts. For county-level context, see the Eastland County activity profile, which shows aggregates only.
The unit produces from the Lower Duffer formation — a specific named member of the broader Pennsylvanian sequence. Duffer-target wells are notable in Eastland County for their somewhat higher per-well productivity compared to the dominant Marble Falls and Strawn completions.
Byrne Oil Company is a smaller private operator focused on the Adams field area.
Mineral interests in the Duffer "A" Unit typically take one of these forms:
Producing royalty interest — your tract’s contribution to the unit’s monthly revenue, paid by the operator
Non-producing mineral interest — fee mineral ownership in a tract currently outside active producing zones
Overriding royalty interest (ORRI) — royalty carved out of a working interest
Non-participating royalty interest (NPRI) — royalty interest with no leasing or development rights
Many Duffer "A" Unit interests trace their original lease bonus payment to the 1917-1925 Ranger oil boom era, with current ownership having passed through 3-5 generations of heirs.
