The Houston-based firm has branch offices in Calgary, CA and Denver.
Trusted Petroleum Experts
For the last 10 years, Ryder Scott has been the most widely used consulting firm for preparing annual petroleum reserves certifications for filers with the U.S. Securities and Exchange Commission, according to research firm John S. Herold. Ryder Scott also serves clients listed on the London, Toronto, Hong Kong, Australian and other stock exchanges.
The firm issues reserves certifications considered to be highly reliable by banks and private investment groups. The “green book” report helps mitigate risks in committing capital for acquisitions, exploration, field development, redevelopment, infrastructure and refinancing.
Major banking institutions establish reserves-based loan amounts, monitor credit lines and determine guarantees based on report values. The report also serves as a resource in screening and due-diligence reviews of acquisitions, divestitures and mergers.
Ryder Scott provides a complete range of professional engineering, geoscientific and economic evaluation services.
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 who 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 perforate and stimulate the producing formation.
The firm continued to implement the best techniques under total engineering control to slow the production decline in the Bradford area during the 1940s. Ryder Scott used selective plugging in water intakes. The firm recommended improvements in core acquisition, logging, completion practices, injection waters 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 the late 1960s, Ryder Scott acquired Robert W. Harrison & Co., moved to Houston and transitioned from waterflood design to evaluation engineering.
Today, Ryder Scott Petroleum Consultants bears little resemblance to the fledgling core-analysis laboratory of the 1930s.
However, the firm still retains the principles of its founders — that oil and gas projects be evaluated and engineered to the highest professional and ethical standards.See more
