Coleman Ranch Field Discovery Well

🏛️The era

When the Westbrook Field's T&P No. 1 came in during 1920, West Texas was still mostly cattle country: wide ranches, small railroad towns strung along the Texas and Pacific line, and a landscape that looked more promising for grazing than for fortune. Oil had already remade parts of Texas. The Spindletop gusher near Beaumont in 1901 had turned the state into a petroleum power. But the vast, dry country to the west was still largely untested.

That changed quickly in the 1920s. The Westbrook discovery, the marker tells us, marked the start of commercial oil production in the Permian Basin. That enormous sedimentary basin stretches across West Texas and into southeastern New Mexico. Once word spread that oil could be pumped here at a profit, landowners, promoters, lease buyers and drilling crews swept into places like Mitchell County, hoping the next hole would be the big one.

It was a period of trial and error. Geology was still a young science in the oil patch, and much drilling amounted to educated guessing. Wildcatters sank wells on hunches, on a neighbor's luck, or on the enthusiasm of local boosters. Many wells came up dry or produced too little to matter. The Coleman well belongs to that hopeful, uncertain moment.

👥People & events

At the center of this story is Dr. Preston C. Coleman, a Mitchell County physician who was also a civic leader and an early promoter of local oil development. It is easy to picture a small-town doctor, who knew every family in the county, catching the excitement that followed the Westbrook strike. The P.C. Coleman No. 1 was drilled on his own land and completed in January 1923.

The well never roared. It was a slow producer, and its operators tried to wake it up with nitroglycerine, a common oil-field practice of the day called "shooting" a well. The idea was to fracture the rock around the bottom of the hole so more oil could flow in. The boost was only temporary. Then came the detail that makes this marker memorable: the well was plugged with a cedar stump, a very frontier solution to a modern industrial problem.

In 1925 Frank Kelley, a landman for Magnolia, pulled the stump, and the well started flowing again. Magnolia kept it going with occasional pumping for years, but the yields stayed small, and the company abandoned it in 1940.

The Coleman family's connection to oil did not end there. In 1946, large quantities of oil turned up southwest of the old discovery well, on former public school land that Dr. Coleman's son Walter had filed on back in 1900. Nearly half a century after that filing, the ground finally delivered what the family had long believed was down there.

🇺🇸Its place in the American story

The Permian Basin became one of the most productive oil regions in the world. Its output fueled America's growing car culture, its industry and, in time, its wartime mobilization. Famous gushers tend to get the headlines, but a basin like this was really proven one modest well at a time. Each of those wells added a little more evidence about where the oil lay and how far the productive rock extended.

The Coleman well's contribution was confirmation. The marker explains that it showed further oil development was possible on the Eastern Shelf of the Permian Basin. That kind of knowledge had real value: it encouraged companies to keep leasing and drilling, and the 1946 discovery nearby showed the encouragement was justified.

The story also shows how oil wealth in Texas often ran through ordinary landholdings. Ranchland, family property and even former public school land filed on around 1900 could suddenly matter to a national industry. The ties between land, luck and patience that you see here repeated themselves across the American West.

🧭If you visit

Keep your expectations modest and your imagination busy. The marker notes that the discovery well site, about two-thirds of a mile southwest of the marker, is marked today only by a concrete well cap on a concrete base. You won't find a towering derrick or a grand monument, just a plain reminder of where a small-town doctor's hopes met the rock below.

The open Mitchell County landscape is part of the experience. Look around at the ranch country and the working oil equipment you may see in the region, and it is easy to picture the 1920s rush that brought drillers, lease hunters and dreamers to this corner of West Texas.

The marker fits naturally into a road trip across the Permian Basin, where oil history is everywhere once you start looking for it. Pair it with other oil-patch sites and small railroad towns along the old Texas and Pacific corridor to see how a cattle frontier turned into one of the great energy regions on earth. As always, respect private property and stay on public roads.
