Former Marland Oil executive confounded geologists, launched lengthy career as independent producer.


When Fort Worth wildcatter W.A. “Monty” Moncrief drilled a well in East Texas in January 1931, he revealed the true extent of an oilfield discovered months earlier miles away.

On January 26, 1931, in Gregg County, Fort Worth independent oilman W.A. “Monty” Moncrief and two partners completed the Lathrop No. 1 well. The well produced 320 barrels of oil per hour (7,680 barrels a day) from a depth of 3,587 feet. As the Great Depression worsened and East Texas farmers struggled to survive, the third wildcat well miles from two earlier discoveries proved the existence of a giant oilfield.

Moncrief, who had worked for Marland Oil Company in Fort Worth after returning from World War I, drilled in an area few geologists thought petroleum production a possibility. He and fellow oil operators John Ferrell and Eddie Showers thought otherwise.

Moncrief’s well was 25 miles north of Rusk County’s already famous October 1930 Daisy Bradford No. 3 well drilled by Columbus Marion “Dad” Joiner. The Moncrief discovery well was 15 miles north of the Lou Della Crim No. 1 well drilled near Kilgore three days after Christmas.

At first, the distances between these “wildcat” discoveries convinced geologists, petroleum engineers (and experts at the large oil companies) the wildcat wells were small, separate oilfields. They were wrong.

Three Wells, One Big Oilfield

However, to the delight of other independent producers and many small, struggling  farmers, Moncrief’s Lathrop discovery showed that the three wells were part of  a massive oil-producing field — the largest ever at the time. As a drilling boom exploded, further development revealed the “Black Giant” East Texas oilfield stretching 42 miles long and four to eight miles wide.

The region’s unique history is exhibited at the East Texas Oil Museum, which opened in 1980. Founding director Joe White, who retired in 2014, notes museum at Kilgore College “houses the authentic recreation of oil discovery and production in the early 1930s in the largest oilfield inside U.S. boundaries.”

After more than half a century of major discoveries, William Alvin “Monty” Moncrief died in 1986. His legacy has extended beyond his good fortune in East Texas.

The family exploration business established by “Monty” Moncrief  in 1929 would be led by sons W.A. “Tex” Moncrief Jr. and C.B. “Charlie” Moncrief, who grew up in the exploration business. In 2010, Forbes reported that 94-year-old “Tex” made “perhaps the biggest find of his life” by discovering an offshore field of about six trillion cubic feet of gas.

Moncrief Philanthropy

Hospitals in communities near the senior Moncrief’s nationwide discoveries, including a giant oilfield in Jay, Florida, revealed in 1970, and another in Louisiana, have benefited from his drilling acumen.

Moncrief and his wife established the William A. and Elizabeth B. Moncrief Foundation and the Moncrief Radiation Center in Fort Worth, as well as the Moncrief Annex of the All Saints hospital. Buildings in their honor have been erected at Texas Christian University, All Saints School, and Fort Worth Country Day School.

Supported throughout the 1960s and 1970s by the Moncrief family, Fort Worth’s original Cancer Center, known as the Radiation Center, was founded in 1958 as one of the nation’s first community radiation facilities. 

In 2013, the $22 million Moncrief Cancer Institute was dedicated during a ceremony attended by “Tex” Moncrief Jr. “One man’s vision for a place that would make life better for cancer survivors is now a reality in Fort Worth,” noted one reporter at the dedication of the 3.4-acre facility at 400 W. Magnolia Avenue.

Early Days

Born in Sulphur Springs, Texas, on August 25, 1895, Moncrief grew up in Checotah, Oklahoma, where his family moved when he was five. Checotah was the town where Moncrief attended high school, taking typing and shorthand — and excelling to the point that he became a court reporter in Eufaula, Oklahoma.

To get an education, Moncrief saved $150 to enroll at the University of Oklahoma at Norman, where he worked in the registrar’s office. He became “Monty” Moncrief after initiation into the Sigma Chi fraternity. During World War I, Moncrief volunteered and joined the U.S. Cavalry. He was sent to officer training camp in Little Rock, Arkansas, where he met, and six months later married, Mary Elizabeth Bright on May 28, 1918.

Although sent to France, Moncrief saw no combat. The Armistice was signed before his battalion got to the front.

After the war, Moncrief returned to Oklahoma where he found work at Marland Oil, first in its accounting department and later in its land office. When Marland opened offices in Fort Worth in the late 1920s, Moncrief was promoted to vice president for the new division. 

In 1929, Moncrief would strike out on his own as an independent operator. He teamed up with John Ferrell and Eddie Showers, and they bought leases where they ultimately drilled the successful F.K. Lathrop No. 1 well, which turned out to be the northernmost extension of the 130,000-acre East Texas field, largest ever in the lower-48 states.
