Talco Field runs across northwest Titus and northeast Franklin counties in northeast Texas, along the fault structure that forms part of the Mexia-Powell-Talco fault zone at the north edge of the East Texas Basin. The discovery well was completed on March 13, 1936, establishing the first Paluxy production along the fault zone. Talco produces heavy, low-gravity crude from the Paluxy sandstone near 4,200 feet, and the field had produced more than 275 million barrels within about fifty-five years of discovery. Production continues today at modest rates.

Northeast Texas had been drilled without much success along the Mexia-Talco fault trend for years before the Talco discovery well came in on March 13, 1936. That well proved the Paluxy sandstone to be a major oil-producing section in northeast Texas, opening a play that had been overlooked while attention focused on the giant East Texas field to the south. The small farming community of Talco turned into a boomtown almost overnight, with the population and commerce of Franklin and Titus counties reshaped within a season.
The crude proved to be unusual. Talco oil is brownish black to black, with gravity ranging from about 16 degrees in the lower part of the oil column to slightly more than 25 degrees higher up. Heavy oil is harder to lift, harder to move through pipe and worth less at the refinery gate than light sweet crude, so the field required different production practices than its lighter neighbors. Development nevertheless proceeded rapidly, and Talco became one of the largest fields in the northern part of the East Texas Basin.
Water became the dominant operating problem early. By November 1947 salt water made up nearly seventy percent of the gross fluid produced, and most of that water was disposed of by injection back into the Paluxy and into overlying salt water sands. Managing water, both to dispose of it and to use it for pressure support, has defined operations at Talco ever since. Cumulative production reached about 266 million barrels by the end of 1984 and passed 275 million within a few more years.
Talco produces from the Lower Cretaceous Paluxy Formation at roughly 4,200 feet, on the downthrown side of the Mexia-Powell-Talco fault zone where salt movement at depth created a long, faulted trap along the basin margin. The productive interval consists mainly of fluvial sandstones; about a quarter of the Paluxy section in the oil column is effective oil sand, averaging around forty-four feet thick with porosity near twenty-five percent and permeability measured in thousands of millidarcys. Excellent permeability offsets the heavy oil, which is why the field produced so well despite low gravity crude.
Talco has been managed as a water handling field for most of its life. Injection into the Paluxy and shallower disposal sands began as a way to deal with enormous produced water volumes and evolved into pressure support that sweeps heavy oil toward producing wells. Because the crude is viscous and the water cut is very high, lifting and separating fluid dominates operating cost, and the economic limit is usually reached long before the reservoir runs out of oil. Operators today concentrate on pump maintenance, water disposal capacity and selective workovers rather than field-wide expansion.
Talco royalties are small and heavily exposed to operating cost, because heavy crude sells at a discount and every barrel of oil arrives with many barrels of water. That combination means payments are sensitive to price swings, and marginal leases can be shut in when prices fall. Owners should treat the interest as a modest, variable income stream rather than a growth asset, and price it accordingly.

County-level well data, production charts, and selling guides for the counties this field spans:
Talco produces heavy, low-gravity crude that sells at a discount to light sweet oil, and the wells make far more water than oil. Both factors reduce net revenue per barrel and per well, so identical decimal interests pay less here than they would in a light oil field.
Not automatically. Whether a lease survives a production interruption depends on its habendum, shut-in and cessation clauses and on Texas case law. Many marginal northeast Texas leases have been shut in and revived over the years. The lease document itself is the place to start.
Yes. Many interests in this area are fractions of a fraction after several generations of inheritance, and we regularly evaluate them. Send recent check stubs or the lease name and we will provide a free written offer, including cases where the answer is that holding makes more sense for you.
