Ryder Scott Company Petroleum Engineers began operations in Bradford, PA, in 1937. Formerly an oil producer in the early to mid 1930s, the later venture was the first engineering firm and research laboratory in the world devoted to solving waterflood problems. Harry M. Ryder and David Scott Jr. formed the partnership after being asked for technical assistance by producers that had noticed the success of Ryder Scott-engineered waterfloods in the Bradford field. The firm originated several techniques. Donald T. May, the first employee, pioneered chip-coring analysis to provide accurate petrophysical data from a single plug of sand. Ryder, an electrical engineer, developed selective shooting. That well-completion technique focused on selecting correctly sized and placed nitroglycerin shots to fracture and stimulate the producing formation. The firm continued to implement techniques under total engineering control to slow the production decline in the Bradford area during the 1940s. Ryder Scott used selective plugging in water-injection wells. The firm recommended improvements in core acquisition, logging, completion practices, injection water quality and pressures, well spacing and oilfield equipment. With the Bradford area’s inevitable decline in the 1950s, Ryder Scott moved to Wichita Falls, TX, to design successful secondary recovery projects. In 1967, Ryder Scott acquired Robert W. Harrison & Co., moved to Houston and transitioned from waterflood design to evaluation engineering, which is the core service offering of Ryder Scott. The firm independently estimates oil and gas reserves, future production profiles and cashflow economics, including discounted net present values. With offices in Houston, Denver and Calgary, the firm performs more than 800 consulting studies a year for major, independent and state-owned oil and gas producers as well as for pipeline companies, investors, banks, government agencies and accounting and law firms. Details are posted on the firm’s website at ryderscott.com. The current CEO, Don Rosele, has presided over substantial growth since taking over. His experience includes a BS degree, Petroleum Engineering, University of Texas, 1971; MS degree, Petroleum Engineering, University of Texas, 1973. Industry Sponsored Short Courses in Pressure Transient Analysis and Well Log Evaluation. == See also == * Gaffney, Cline & Associates 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ryder Scott」の詳細全文を読む スポンサード リンク
