Ryder Scott Company is a petroleum consulting firm based in Houston, Texas, United States. The firm independently estimates oil and gas reserves, future production profiles and cashflow economics, including discounted net present values.[citation needed] It assesses oil reserves and evaluates oil and gas properties.

History

The company was founded in Bradford, Pennsylvania on July 1, 1937, by Harry M. Ryder, a prominent petroleum engineer who died in 1954, and David Scott, Jr.

In 1967, Ryder Scott acquired Robert W. Harrison & Co., moved to Houston, and transitioned from waterflood design to evaluation engineering, Ryder Scott's core business.

In 2004, after Shell disclosed major downward revisions to its proved reserves, Ryder Scott was hired to provide independent review and reserve estimates to help restore investor confidence.

Today, Ryder Scott maintains offices in Houston, Denver, and Calgary, employing more than sixty petroleum engineers and geoscientists.
