Ector County Discovery Well
Penwell, Ector County, Texas
Marker Inscription
The discovery of Oil in Ector County December 28, 1926, marked the beginning of a new economic era for this region. The first Well, " J.S. Cosden No.1-A W.E. Connell ", was named for the driller and owner of land. Its meager initial output of 38 barrels per day did not cause much excitement, but experts insisted that vast oil deposits lay under area (permian basin). In 1929, Robert Penn's Gusher catapulted Odessa to boom-town fame. Oil has sustained the area economy since then, although the discovery Well was pugged and abandoned in 1940. Recorded Texas Historic Landmark - 1967.

The Story
On December 28, 1926, a well drilled on W.E. Connell's land struck oil in Ector County, quietly opening the vast Permian Basin that lay beneath the West Texas plains. Its first-day yield of 38 barrels stirred little excitement, but geologists were certain of the riches below, and Robert Penn's 1929 gusher soon turned Odessa into a booming oil town. Petroleum has anchored the regional economy ever since, even though the discovery well itself was plugged and abandoned in 1940.
Why it matters
This modest first well marked the opening of the Permian Basin, one of the most productive oil regions in American history and an engine of 20th-century Texas growth.
The story behind this marker
AI contextThe era
In the 1920s, West Texas was a land of ranches and small farms scattered across a vast, dry landscape — hardly the industrial powerhouse it was about to become. Beneath that quiet surface, though, lay one of the greatest concentrations of oil on earth, still largely unsuspected and untapped.
The decade was the height of America's oil age. The automobile was transforming the country, demand for petroleum was soaring, and prospectors and companies were fanning out across the continent chasing the next great field. Texas had already seen spectacular strikes elsewhere, and the whole state was primed for the next one.
Into this moment came the first serious drilling in this corner of West Texas — a probe into ground that geologists suspected held far more than its sleepy surface suggested. The result would rewrite the economic future of the entire region.
People & events
The breakthrough came on a December day in 1926, when a well drilled on a local landowner's ground struck oil. In the custom of the oil patch, the well took its name from both the man who drilled it and the man who owned the land — a small linguistic partnership between labor and property that opened a new era.
At first, it hardly seemed the stuff of legend. The well's initial output was modest — a trickle, by the standards of the gushers people dreamed about — and it stirred little immediate excitement. But the experts were unmoved by the small number; they were certain that a vast reservoir, the Permian Basin, lay beneath the surrounding country, and they were right.
Confirmation came a few years later, when a far more dramatic gusher nearby helped turn the town of Odessa into a genuine boom town. The country filled with the noise and traffic of the oil business, and it never really quieted again — even though the modest discovery well that started it all was eventually plugged and abandoned, its work long since done.
Its place in the American story
This unassuming well marks the opening of the Permian Basin, which would grow into one of the most productive oil regions in the history of the United States. What began as 'meager' output signaled the presence of a resource that would fuel American industry, transportation, and prosperity for generations.
The discovery also reshaped Texas itself. Oil transformed the state's economy and identity in the twentieth century, turning sparsely populated ranch country into engines of national energy — with all the wealth, growth, and volatility that boom industries bring.
And it is a fine illustration of how history often turns on small, unglamorous beginnings. The gushers and boom towns get remembered, but they were made possible by a first, modest well that proved the experts' hunch about what lay below — a reminder that world-changing developments frequently start with a quiet result that only the knowledgeable recognize.
If you visit
This is a landmark marker in oil country, so let the setting do the work: wide West Texas sky, the low hum of an industry that has never stopped, and the knowledge that the ground beneath you launched one of America's great energy stories. The discovery well itself is long gone, so what you are really reading is a historical spot where an era began.
As you look around at the pumpjacks and infrastructure that define the modern landscape, try to reset the scene to 1926, when all of this was still a gamble and a single modest well was the only evidence of the fortune below. The contrast between that humble start and the vast operation around you is the heart of the visit.
It makes a natural stop on any drive through the Permian Basin, pairing well with the region's other oil-history sites. Keep in mind this is working country — stay on public roads and respect active industrial and private property as you take it in.

Penwell
Penwell, TX
Penwell was the cradle of Ector County's oil boom, born as the wide-open town of "Derrick City" in 1927 after driller Josh Cosden's late-1926 discovery—though the crowd scattered when the first well pumped only twenty barrels a day. A far richer strike on Robert Penn's land in 1929, followed by the 600-to-700-barrel Penn Well, revived the field, and a bustling tent city grew up around the post office established in 1930. It endured as a distribution and shipping hub, earning the name "The Crossroads of the Oil Patch."
Sand Hills Section House
Monahans, TX
Built in 1903 by the Texas & Pacific Railway, this section house sheltered one of the track foremen stationed every twenty miles along the line. In the harsh Permian Basin, such houses offered water and human aid to men bogged down in sand or stranded in storms, a lifeline for the crews who kept the rails running.
Notrees
Notrees, TX
When a post office was established in C. J. Brown Jr.'s drugstore in 1944, the sparse West Texas locale was given the fitting name "Notrees" in response to a Post Office Department request for a title suited to the place. Residents later answered the joke by planting shade trees. The community grew into a hub of the Permian Basin's gas-processing industry and home to Otto's Boys Ranch.
Million Barrel Tank
Monahans, TX
When crude oil gushed out of the West Texas Permian Basin in the late 1920s, production briefly outran the pipelines and refineries that could handle it. Shell Oil's answer, in 1928, was this astonishing open earthen reservoir—covering eight acres and lined to hold more than a million barrels—built around the clock by crews using hand tools and horse-drawn scrapers. It was filled to the brim only once, later flirted with a second life as a lake-side recreation park, and finally settled into its role as a monument to the boom that made it.
