James Cleo Thompson Jr. (August 25, 1930 – November 19, 2010), known as Jimmy or Jimmie Thompson, was an American independent oil and gas operator based in Dallas, Texas. With his father he assembled an oil and gas business beginning in 1952 that ultimately operated more than 925 wells and held interests in approximately 9,000 wells, the majority in the Permian Basin of West Texas.[1][2] He was named a "Texas Discoverer" by the Railroad Commission of Texas in 1994 for the discovery of four fields,[2] and in 2017 he was posthumously inducted into the Petroleum Hall of Fame of the Permian Basin Petroleum Museum in Midland, Texas.[1][2]

Early life and education

[edit source]

Thompson was born in Dallas on August 25, 1930, to James Cleo Thompson Sr. (1898–1975), a Dallas attorney and independent oil operator, and Christine C. Thompson.[3][4][5] He attended Highland Park High School in University Park, where he played football.[6]

He enrolled at Southern Methodist University (SMU) in 1948, studying engineering and geology and playing for the SMU Mustangs football team.[2] He appeared on SMU's 1951 varsity roster as "Jimmie Thompson" wearing number 50.[7] From 1948 to 1950 he served in the United States Naval Reserve as an airman apprentice (V6 USNR) and later enlisted in Air Force ROTC at SMU.[2] He remained at SMU until 1952 and had originally intended to attend law school.[6]

Career

[edit source]

Entry into the oil business (1952)

[edit source]

In 1952, the year he had planned to begin law school, Thompson and his father purchased twelve oil wells near Crane, Texas. The younger Thompson was sent to West Texas to return the wells to production, and the experience persuaded him to enter the oil business rather than the law.[2] The father and son acquired additional leases and opened a field office in Crane.[2][6]

In 1960, when the Thompsons began drilling on the Paul Moss ranch near Odessa, the Crane office was relocated to Yukon Road in Odessa, where the company's West Texas field office still operates.[2] The Thompsons later organized Thompson Petroleum Corporation as a corporate parent for the family's oil and gas activities.[8]

Permian Basin development

[edit source]

Beginning in the early 1950s, Thompson was associated with the discovery, development, and unitization of fields including Hoban, West Means, Furman Mascho, University 29, University 21, Slaughter, and Levelland Cowden South.[2][1]

The Railroad Commission of Texas conferred on him the title "Texas Discoverer 1994" for the discovery of four fields that year: the West Richardson (Strawn), Earnie Pinnell (Fusselman), West Richardson North (Wolfcamp), and West Richardson (Ellenberger) fields.[2]

According to the Permian Basin Petroleum Museum, Thompson was an early adopter of new production technology: he used sand fracturing and rubber-ball diversion techniques in the early 1950s, and in the late 1980s he was among the smaller independent operators to apply three-dimensional seismic imaging.[2][1]

Ozona gas and Delaware Basin acreage

[edit source]

In the 1980s, Thompson's companies began drilling natural-gas wells around Ozona, Texas, where they reported significant discoveries and developed associated midstream businesses for gas gathering and processing.[6] Beginning in the early 2000s, Thompson assembled acreage in the Delaware Basin of West Texas; the Petroleum Museum credits two of those fields with peak production exceeding 40,000 barrels of oil per day.[6] By 2017, his companies operated more than 925 wells and held interests in approximately 9,000 wells, most in the Permian Basin.[2][1]

Affiliated companies and other interests

[edit source]

Thompson's principal operating entities included Thompson Petroleum Corporation, J. Cleo Thompson and James Cleo Thompson, Jr., L.P., and Wes-Tex Drilling Company, L.P., which carried out drilling operations across Texas, Louisiana, and Oklahoma from the late 1970s onward.[9][10] The companies were headquartered in the Republic Center complex at 325 N. St. Paul Street in downtown Dallas.[3][11]

Outside oil and gas, Thompson served as chairman of Crockett National Bank in Ozona and owned cattle ranches in Texas and Colorado.[8]

Mesa Petroleum litigation

[edit source]

In April 2015, T. Boone Pickens's Mesa Petroleum Partners, LP filed suit in the 143rd Judicial District Court of Reeves County, Texas, naming Baytech LLP, Patriot Resources, Inc., J. Cleo Thompson and James Cleo Thompson, Jr., LP, and Delaware Basin Resources, LLC, as defendants.[12] Mesa alleged that the defendants had breached a 2007 participation agreement covering acreage and wells in the "Red Bull" area of Reeves and Pecos counties.[13][14]

After a five-week trial in November 2016, a jury returned a verdict in favor of Mesa, finding that the defendants had breached duties to Mesa.[13] In a 2017 final judgment, District Judge Mike Swanson ordered Delaware Basin Resources and Baytech to pay Mesa $117 million plus prejudgment interest, while setting aside the jury's liability finding against the Thompson partnership; lawyers for the Thompson partnership characterized that portion of the ruling as a "take-nothing" judgment in their client's favor.[14][15] Mesa appealed, and on February 28, 2018, the Eighth Court of Appeals in El Paso dismissed the appeal on Mesa's motion after the parties resolved the matter, ending the litigation.[16]

Personal life

[edit source]

Thompson married Dorothy "Dolly" Kuntz Thompson, a 1953 SMU alumna; the couple had two daughters, Jean Christine "Christy" Thompson and Linda Thompson Gordon, both of whom worked in the family business.[5][8][3] He was a longtime SMU football fan and an avid hunter.[3]

Thompson died in Dallas on November 19, 2010, at age 80, after a battle with bladder cancer. Funeral services were held at Sparkman/Hillcrest Funeral Home.[3] Forbes described him posthumously as a "wildcatter."[17]

Philanthropy

[edit source]

Thompson was a longtime supporter of educational institutions.[6] In 1984, Thompson, his wife Dorothy, and his mother Christine C. Thompson endowed the James Cleo Thompson Sr. Endowed Scholarship at the SMU Dedman School of Law, which provides financial aid to law students who demonstrate academic achievement and community service.[18][19] The same year, the family established the James Cleo Thompson Sr. Professorship at Dedman School of Law, a chair held by Peter Winship.[5]

Honors

[edit source]
  • Texas Discoverer, Railroad Commission of Texas, 1994 — for the discovery of the West Richardson (Strawn), Earnie Pinnell (Fusselman), West Richardson North (Wolfcamp), and West Richardson (Ellenberger) fields.[2]
  • Permian Basin Petroleum Hall of Fame, Permian Basin Petroleum Museum, Midland, Texas — inducted May 9, 2017, alongside Joseph B. McShane Jr. and Curtis W. Mewbourne.[1]

Legacy

[edit source]

After Thompson's death in 2010, his widow and daughters retained the family's oil-and-gas interests, and from 2017 the next generation began diversifying the family's holdings beyond exploration and production while continuing oil-and-gas operations.[8] His daughter Jean Christine "Christy" Thompson serves as principal of the J. Cleo Thompson Family Office, headquartered in Dallas, which manages Thompson Petroleum Corporation and the family's other assets.[17][20][21]
