He was a legendary oilman who united with J.S. Abercrombie to discover gushers like the Old Ocean field in Brazoria County. Thus, he built up the oil and ranching empire across Texas that eventually came into Daniel Harrison, III's possession. Daniel's father, Dan Jr. kept the oil business alive and also ran a ranchland as he was a master breeder of quarterhorses. Following in his father's footsteps, Dan III maintains a quarterhorse operation on a ranch in Fulshear to this day. In addition, Dan III was the one to conclude the biggest ever deal for the family in 2010 when he managed to lease his 100,000-acre ranch in the Eagle Ford Shale in South Texas to Shell Oil for $1 billion in cash, along with royalties for future oil and gas production.
