Santa Rosa Energy, Ltd. was founded in 2005 by Roger S. Braugh, Jr., a lawyer and descendant of the McGill family, who had owned and operated over a hundred thousand acres of South Texas ranches with significant oil and gas production dating to the 1930s. Mr. Braugh's oil and gas experience began when working as an oilfield roustabout in Brooks County as a teenager. His expertise further developed in handling complex oil and gas litigation concerning royalty, drilling and production disputes as a lawyer, and eventually evolved to acquisition and interpretation of three dimensional seismic data, prospect development, and drilling and production operations.
The Company was named after the ranch Mr. Braugh was raised on, the Santa Rosa Viejo, an 18,000 acre ranch in Kleberg County and Kenedy County, Texas. The McGill family ranches had significant oil and gas operations, and included the Kelsey Field in Brooks County and Starr County, Santa Rosa Field in Kenedy County, and McGill Field in Kleberg County and Kenedy County. The company's logo is a version of the McGill family triangle brand.
Santa Rosa Energy, Ltd. was originally founded to pursue development of oil and gas prospects on McGill family minerals, but soon expanded to pursue prospects and opportunities on other lands. The company has remained privately funded and closely-held and has purposely avoided the institutional pressure that would result from outside financiers and investors.
At its inception and to this day, Santa Rosa's strategy has been to acquire or develop prospects and retain non–operated working interests in assets with substantial development potential. Avoiding being an operator has allowed Santa Rosa to select operators for each project that have operational expertise in particular fields, formations or geographic areas, and to keep its investments and development targets tight. Eventually, Santa Rosa's strategy may evolve to include operations through its operating affiliate, Santa Rosa Operating, LLC.
