Conroe Oil Field
Conroe, Montgomery County, Texas
Marker Inscription
One of the great petroleum areas of the Texas coastal region. Opened December 13, 1931, by the discovery well of George Strake (No. 1 South Texas Development Company), about 1.4 miles west of here. Initial daily flow: 15,000,000 cubic feet of gas, along with white gasoline. Strake's second well, a 900-barrel-a-day producer, and the Heep Oil Corp. No. 1 Freeman (both coming in during June 1932) proved existence of a large field. Fast-paced drilling ensued. In January 1933 Madeley No. 1, of Kansas Standard, came in as a wild well and on fire. TNT charges and tons of earth did not smother the fire; it burned about three months. Cratering spread to Harrison and Abercrombie well nearby, and that gushed out of control. In January 1934 a driller for Humble "killed the blowout," by using directional drilling for first time in coastal Texas. This saved the field. (The crater is 600 feet deep.) The Conroe field was the first in Texas to adopt 20-acre spacing, before this was mandatory under conservation rules. It has yielded over 400,000,000 barrels of oil; now produces at the yearly rate of 5,300,000 barrels. After the dramatic discovery here, Montgomery County developed eleven other oil fields, and has reserves for continuing production. (1967)

The Story
On December 13, 1931, George Strake's discovery well opened the Conroe Oil Field, one of the great petroleum finds of the Texas coastal region during the depths of the Depression. Explosive early wells—including a wild well that caught fire and burned for months—proved a giant field before a pioneering directional-drilling operation by Humble in 1934 tamed a runaway blowout. The field went on to yield over 400 million barrels and helped make Montgomery County an oil powerhouse.
Why it matters
Conroe's crisis and rescue advanced the drilling techniques that shaped the modern oil industry, and its riches buoyed a Texas economy battered by the Great Depression.
The story behind this marker
AI contextThe era
When George Strake's discovery well came in near Conroe in December 1931, the country was sinking deeper into the Great Depression. Banks were failing, farm prices had collapsed, and many towns across East and Southeast Texas were getting by on very little. A new oil field didn't just mean fortunes for wildcatters. It meant paychecks for drillers, roughnecks, truckers, boardinghouse keepers, and merchants.
The early 1930s were also a chaotic time for Texas oil. The giant East Texas field had opened only a year before and flooded the market with crude, and prices fell so far that the state struggled to control production. The rules that now seem obvious, like how closely wells may be drilled and how much each may produce, were still being fought over in courtrooms and in the Capitol.
That is why Conroe matters beyond its own barrels. It arrived in a pine-woods county north of Houston just as Texas was learning, the hard way, that oil had to be managed and not simply grabbed.
People & events
The story begins with a wildcatter's gamble. George Strake drilled his discovery well about a mile and a half west of the spot where the marker stands, and it came in roaring with natural gas and light, clear "white gasoline" rather than the black crude everyone was hoping for. It was promising, but it was not yet proof.
The proof came in June 1932. Strake's second well and the Heep Oil Corporation's No. 1 Freeman both came in as solid oil producers, and suddenly Conroe was a real field. Drilling rigs went up fast as operators raced to claim their share.
Then came the disaster. In January 1933 a Kansas Standard well, Madeley No. 1, blew out wild and caught fire. Crews threw explosives and tons of dirt at it and still could not put it out, and it burned for roughly three months. The ground around it caved into a crater that spread to a neighboring well, which then gushed out of control. For a while, the whole field seemed to be at risk.
The rescue came from underground. In January 1934 a Humble driller drilled at an angle from a safe distance to reach the runaway well deep below the surface and kill the blowout. It was the first time the technique had been used in coastal Texas, and it saved the field. The crater it left behind is said to be 600 feet deep.
Its place in the American story
Conroe tells a story that runs through all of modern American energy: a fast discovery, a reckless rush, and then the slow work of taming a resource that can turn dangerous. Directional drilling, the angled boring that stopped the Conroe blowout, went on to become a standard tool across the industry. It was used to control wild wells, reach oil beneath places a rig couldn't stand, and eventually drill offshore.
The field also looked ahead on conservation. According to the marker, Conroe adopted 20-acre spacing between wells before regulations required it. At a time when overdrilling was wasting oil and wrecking prices across Texas, that restraint showed that orderly development could make a field last longer and pay better.
And it did last. With hundreds of millions of barrels produced and more oil fields opening across Montgomery County afterward, Conroe helped make the Houston region the energy capital it is today, and it did so in the middle of the Depression.
If you visit
Today Conroe is a busy, growing city on the northern edge of greater Houston, and it can be hard to picture the derricks, the mud, and the three-month fire. Standing at the marker is the best way to do it. Remember that the discovery well lay about a mile and a half to the west, and try to imagine the pine woods filled with rigs as crews raced to drill.
It's worth reading the marker slowly, because it packs a whole drama into a few lines: gas, gasoline, gushers, fire, a crater, and a daring rescue from underground. It's a great one to read out loud to kids. The idea that engineers stopped a fire by drilling sideways, deep underground, tends to stick.
Conroe is an easy stop on a drive north from Houston along I-45. Pair it with the region's pine forests and lakes, or with other oil-history stops around Southeast Texas, and the marker becomes a chapter in a larger story about how oil remade this part of the state.

Crater Hill
Conroe, TX
In 1933 the Madeley wells, drilled by Standard Oil of Kansas, came in on fire and threatened to destroy the entire Conroe oil field, sending flames as high as 150 feet as crews battled for three months with water, mud, and explosives. Humble Oil finally quelled the inferno with a directional well never before tried on the Texas Gulf Coast, pumping mud into the blowout crater. Crater Lake, born of those explosions, still marks the site.
The Isaac Conroe Property
Conroe, TX
A New Jersey native and Union Army veteran of the Civil War, Isaac Conroe moved to Southeast Texas in 1866 and in 1878 built a sawmill whose lumber business gave rise to the town of Conroe, connected by a tram line to the International and Great Northern Railroad. He became the settlement's first postmaster and built this residence in 1885. From 1889 to 1891 it served as the temporary Montgomery County courthouse until a permanent one was completed, and his son William later expanded the home.
Conroe Telephone Exchange
Conroe, TX
Conroe's telephone service began in 1899 inside Gilbert's Drug Store, where a local exchange grew out of a long-distance line running up from Houston. George Madeley soon bought the operation and ran it from his building on this site, and by the late 1920s it had grown into a busy switchboard staffed by toll, rural, and local operators. A dial system arrived in 1954, carrying the small-town exchange into the modern era.
Conroe Fire of 1911
Conroe, TX
In the early morning of February 21, 1911, a fire broke out in the Capitol Drug Store on Chambers Street and, driven by a north wind, swept through downtown Conroe toward the railroad tracks. The volunteer fire company, armed with a single hand-pulled hose cart and too little water pressure, could not stop it, and sixty-five buildings, businesses, and homes were lost at a cost of some $150,000. In response the city council quickly required fireproof construction, then mandated brick and stone, and downtown rose again in the stately masonry buildings that still stand.
