Michel Thomas Halbouty (21 June 1909 in Beaumont, Texas – 6 November 2004 in Houston, Texas) was an American geologist, petroleum engineer, and wildcatter. Credited with discovering more than 50 oil and gas fields, he twice declared bankruptcy, but came back each time to regain wealth. He authored hundreds of technical articles on petroleum geology, and two book-length histories of famous oil fields. Halbouty is often described, including in his New York Times obituary, as “legendary.”[1]
