Near George West in McMullen County, Texas — The American South (West South Central)
First Producing Gas Well in McMullen County and First Gas Pipeline to San Antonio
(South of Frio River, 1 mi. NE)
Inscription.
Thirty years before the first producing gas well was drilled in this county, traces of salt water, sulphur, gas, and oil in water wells gave hints of the presence of petroleum here. For years wildcat drilling went on, but with only moderate success.
Then in 1908, a well on Charles Byrne's land began to blow warm sulphur water and gas 120 feet into the air every 8 days, arousing much interest. After this discovery, Byrne, a promoter, set out to locate capitalists to develop his petroleum deposits.
Armed with a picture of the gusher and a bottle of area oil, he attracted the attention of W.M. Bee Stephenson, his sons Light and Donald, and others.
The well they drilled here in 1917-1918, on the Tom Brown tract, blew in at 816 feet with 62,000,000 cubic feet of natural gas a day, but for 3 months it spewed out of control because of the intense subsurface pressure and inadequate equipment.
After other producers were drilled, W.M. Stephenson arranged to pipe gas to San Antonio, 68 miles north, in 1922. Among those joining this enterprise was H.A. Pagenkopf, Wichita Falls oil man. Thus petroleum took a leading role in the economy of McMullen County.
Erected in memory of W. M. Stephenson, who, with his two sons, Donald and Light, and his daughter, Alice Stephenson Naylor, and H. A. Pagenkopf, developed the Calliham Gas and Oil Field, from which San Antonio received its first natural gas. (The McMullen County Historical Survey Committee)
Erected 1970 by State Historical Survey Committee. (Marker Number 1854.)
