Born February 9th, 1925, John was the only son of Allie and Curtis Thrash, Sr. living in Galena Park, Texas, where John and his sister, Evelyn, grew to become healthy, happy young adults. He was offered to play Second Chair with the Houston Symphony Orchestra when he was still less than 19 years old. John matriculated in the University of Texas, Austin in 1943, earning a science baccalaureate four years later in Petroleum Engineering His career continued until his passing, interrupted only by his service as a Naval Officer during World War II, in the Pacific Theater, and two years on Guam as a full Lieutenant during the Korean Crisis. He was one of the world's foremost developers of complex, clever reservoir engineering projects and solutions. One such project, the Two Fred's Carbon Dioxide Enhanced Oil Recovery ("EOR") Project, located in the Permian Basin, is still regarded today as one of the most successful EOR projects ever undertaken, accomplished at a time when foreign oil dependency meant domestic production had to be wrought of every available barrel. Most recently, John was principal engineering architect of the highly successful Stagecoach Natural Gas Storage Facility, Owego, NY, which serves New York City and the Northeast U.S. much in the same way the Bammel Facility has served Houston and the Texas Gulf Coast. It was also in West Texas where John met his lovely, intelligent and beautiful wife, Patricia Ruth Francis Thrash, recently moved to the area with her family from California. Patricia and John were soon married and shortly thereafter began their family, first with their daughter Denise, then son John, then youngest daughter, Allison. Each of their children have developed independent careers while still helping to advance the family business, from time to time, that was founded by John and Patricia in the late 1970's. Denise is a criminal defense attorney in Houston, Allison is engaged in a singing and recording career based in Austin, and John is a retired physician who practiced in Houston for a number of years before combining with his father full time to create a thriving, multifaceted energy concern. John is also survived by his sister, Evelyn, and brother-in-law, Gesna B. Davis, Jr., and many beloved family members and dear friends. The family's current day enterprise, eCorp LLC is a vibrant, private, integrated energy company which specializes in mid-stream asset construction, ownership and operation along with natural gas production and energy marketing.
