Oil Industry in Gaines County
Seminole, Gaines County, Texas
Marker Inscription
The first oil lease in Gaines County was in 1912 and the first drilling occurred in 1925. Ten years later the Landreth Co. brought in the first producing well. In 1936 Amerada Oil Co. opened up the Seminole Pool, a major field that yielded 350 wells within a decade. Less than 50 years after that discovery, Gaines County had produced over one billion barrels of crude oil. With several active fields, Gaines ranks as one of the top oil producing counties in Texas. The petroleum industry accounts for much of this area's prosperity. (1979)

The Story
Gaines County's first oil lease dates to 1912, but real drilling waited until 1925, and the Landreth Company brought in the first producing well a decade later. In 1936 Amerada Oil opened the Seminole Pool, which yielded 350 wells within ten years. Less than fifty years after that strike, the county had produced over a billion barrels of crude.
Why it matters
It marks the West Texas oil boom that transformed the arid Permian Basin into one of the nation's great engines of petroleum wealth.

Dan Cobb
Seminole, TX
A Tennessee native, Dan Cobb was the builder who gave early Gaines County much of its shape, constructing both the first county courthouse in 1906 and its 1922 successor, along with a Baptist sanctuary, a schoolhouse, and other landmark buildings. He and his wife Aurelia raised six children in the home they built here in 1906, and he held civic roles and even a federal mail contract spanning three counties. His work and leadership were central to the young county's growth.
Gaines County
Seminole, TX
Gaines County was created in 1876 and named for James L. Gaines, a signer of the Texas Declaration of Independence. Anglo settlement began around 1895, the county formally organized in 1905 with Seminole as its seat, and a courthouse rose the next year. Ranching and farming ruled the economy until the 1930s, when booming oil production reshaped this corner of the West Texas plains.
C. M. Armstrong Building
Seagraves, TX
Clifton Martin Armstrong helped build northern Gaines County from its earliest days, brokering major land deals and selling town lots when Seagraves was founded in 1917. He served twelve years as mayor and, with his wife Carobel — daughter of pioneer rancher Col. D.H. Snyder — was a fixture of community life. In 1926 he raised this building to house his Seagraves Motor Co., and after a fire leveled the block in 1928 it briefly sheltered a bank and the post office.
Discovery Well in the Wasson Field
Denver City, TX
Ranchers L.P. and Ruth Bennett, facing foreclosure amid Depression-era drought, saw their fortunes reversed on October 10, 1935, when wildcatter Red Davidson and Honolulu Oil crews struck oil on their Yoakum County land. The discovery well opened the vast Wasson Field and sparked a boom that gave birth to nearby Denver City in 1939. Petroleum remains the region's economic engine, and the family later donated this ground for a county park.
