Anahuac Oil and Gas Field
Monroe City, Chambers County, Texas
Marker Inscription
Although oil production of major value began in Chambers County in 1916, this prolific Anahuac field was discovered on March 3, 1935, with completion of Humble Oil & Refining Company's A. D. Middleton No. 1 (1.8 mi. SE). The camp which housed Humble crews who developed the field was adjacent to this site. The field encompasses some 14,000 acres of prime rice and grazing land and produces from 21 zones in a highly faulted domal structure. Producing depths range from 6,600 feet to 8,600 feet. Peak production was reached in world War II, when in 1944 annual total was 11,916,137 barrels. discovery well had an original potential of 144 barrels a day from depth of 7,050 feet. It was deepened to 7,088 feet and recompleted March 14, 1935, with a new potential of 518 barrels. Through 1966, A. D. Middleton No. 1 has produced in excess of 390,000 barrels of oil. Over 177 million barrels of oil and 268 billion cubic feet of gas have been produced from the field. (In Chambers County, a pioneer oil producing area, over 475 million barrels of oil have been produced since 1916.) At present, there are 408 wells in the Anahuac field, and it is expected that production will continue into the 21st century.

The Story
The prolific Anahuac field was brought in on March 3, 1935, when Humble Oil & Refining's A.D. Middleton No. 1 struck oil in a highly faulted salt-dome structure beneath the rice and grazing lands of Chambers County. A company camp housed the crews who developed the field, which reached peak output during World War II — nearly 12 million barrels in 1944 alone. Over its life the field yielded more than 177 million barrels of oil and hundreds of billions of cubic feet of gas.
Why it matters
The Gulf Coast oil booms of the early 20th century transformed Texas into an energy powerhouse and fueled American industry through two world wars.
The story behind this marker
AI contextThe era
By the time the Anahuac field came in, the Texas Gulf Coast had been oil country for a generation. The 1901 gusher at Spindletop near Beaumont set off a boom that turned the region into one of the world's great petroleum provinces. Chambers County, the marker notes, had been producing oil of real value since 1916, part of a coastal belt where oil often collected around buried salt domes.
The 1930s were a strange time for a new strike. The Great Depression had crushed prices and livelihoods, and the vast East Texas field, found in 1930, had flooded the market with oil. Still, companies kept exploring. Geology and new techniques were letting them find oil deeper and in more complicated structures than the early wildcatters could reach.
The land above the Anahuac field was working country: rice fields and cattle range on the flat, wet coastal prairie near Galveston Bay. Rice farming and ranching had long been the economic backbone of Chambers County, and the oil field grew up right in the middle of them. Derricks rose among the paddies and pastures.
Within a few years the world was at war, and Gulf Coast oil became a strategic resource. Fuel for ships, planes, tanks and factories poured out of fields like this one, and the Anahuac field hit its peak output in the middle of that conflict.
People & events
The field's story begins on March 3, 1935, when Humble Oil & Refining Company completed the A. D. Middleton No. 1, about 1.8 miles southeast of this spot. At first the well was modest, rated at 144 barrels a day from about 7,050 feet. Humble's crews kept at it, deepening the well just a few dozen feet to 7,088 feet. When it was recompleted on March 14 its potential jumped to 518 barrels a day. That kind of patient, incremental work was typical of how oil fields were actually made.
The men who developed the field lived next to this site in a company camp. Oil camps like this were small worlds of their own: bunkhouses or family cottages, shared routines, and workers who might have followed the boom from field to field across Texas and Louisiana. Much of the field's human story happened here, in the day-to-day lives of drillers, roughnecks and their families.
Underground, the field turned out to be complicated and rich. It sits on a highly faulted dome, with oil and gas found in 21 separate producing zones between about 6,600 and 8,600 feet deep. The field spread across some 14,000 acres. In 1944, at the height of World War II, it produced nearly 12 million barrels in a single year.
The discovery well alone had produced more than 390,000 barrels by 1966. By the time the marker was written, the field had yielded over 177 million barrels of oil and 268 billion cubic feet of gas, with 408 wells still active. Humble Oil itself later became part of what is now ExxonMobil, one more link between this rice-country field and the modern energy industry.
Its place in the American story
The Anahuac field is one piece of the enormous Gulf Coast petroleum system that made Texas central to American energy, and made the United States the dominant oil power of the mid-twentieth century. Fields like this supplied the fuel that ran farms, cars, factories and, above all, a war machine.
Its peak in 1944 is no coincidence. World War II was a war of oil, and American production was one of the Allies' decisive advantages. Nearly 12 million barrels a year from one county's field is a vivid measure of how much domestic crude poured into that effort.
The field also shows a lasting pattern in American land use: industry and agriculture sharing the same ground. Rice farmers and ranchers kept working the surface while wells tapped the deep layers below. That coexistence, sometimes easy and sometimes tense, shaped the economy and landscape of the whole upper Texas coast.
Finally, it reflects how the oil business matured. The early boom-town gushers gave way to the careful engineering of big companies, which mapped faulted domes, produced from dozens of zones, and managed fields to last for decades. The marker's prediction that production would continue into the twenty-first century speaks to that long-view approach.
If you visit
Look around at the flat coastal prairie and imagine what was under your feet: oil trapped more than a mile down in a jumble of faulted rock layers. The camp that housed Humble's crews stood right next to this spot, so you're standing at what was once the domestic heart of the field.
Keep an eye out for the region's two identities side by side. Rice and grazing land still define much of Chambers County, and signs of oil production, such as pump jacks and pipelines, may be visible across the landscape. Watch out for working equipment and private leases, and view them from public roads.
The marker fits naturally into a drive along the upper Texas coast between Houston and Beaumont, a stretch rich in oil history. Pair it with the Spindletop story near Beaumont for the beginning of the Texas oil age, or with nearby Galveston Bay and its birding and wetlands for a change of pace.
The town of Anahuac is also worth a look for its much older history: it was a flashpoint in the tensions that led up to the Texas Revolution. One short drive spans more than a century of Texas history.

Lone Star Canal
Anahuac, TX
In the early 1900s, east Chambers County was becoming rice country, but the crop needs a steady supply of fresh water. Beginning in 1902, Berriman Richard Garland and A. L. Williams dug this canal from the mouth of Turtle Bay to irrigate the fields, and by 1904 the Lone Star Canal Company was shipping rice out by sailing vessel. Salt water intruding during dry seasons repeatedly killed crops, prompting a dam, locks, and a river district to manage the water. Through hurricanes, closures, and changing owners the canal endured and still serves the region's farms and industry.
Harmon Saddle Shop
Hankamer, TX
The Harmon family made saddles in East Texas from before the Civil War, when Joshua Harmon worked leather part-time in Orange as early as 1856. After moving to Chambers County, he partnered with another saddler—Harmon carving the wooden saddletrees, Bingle working the leather—and built a reputation among Gulf Coast cowboys and ranchers. His son Charles formally opened the Harmon Saddle Shop in 1896, and the business, prized for comfort and durability, stayed in the family for generations.
Birthplace of Governor Ross Shaw Sterling
Anahuac, TX
Ross Shaw Sterling rose from a Chambers County farm boy to one of Texas's great oil-and-industry figures, building two wells into the Humble Oil & Refining Company and later shaping Houston through real estate and the newspaper that became the Houston Post. As governor from 1931 to 1933 he steered the state through the depths of the Great Depression, pushing agricultural relief and famously placing oil counties under martial law to enforce production limits. He lost his fortune, then rebuilt it, dying in 1949 as head of new enterprises and a noted philanthropist.
Old River
Old River-Winfree, TX
Old River, a looping channel of the Trinity, drew some of the earliest pioneers to this corner of southeast Texas in the 1820s and 1830s, among them Robert and Eleanor Wiseman on land grants taken up in 1827. Fertile soil and open grassland made it a farming and ranching center whose hides, timber, and charcoal were shipped down to market in Galveston. That trade fostered shipbuilding firms, brick kilns, and ferry operations, seeding a pattern of settlement whose descendants still live in the area.
