Sierra Engineering is a wellbore-construction project management firm that has been in operation since January 1989. Sierra specializes in drilling-completion engineering, fracture treatment design and execution, and workover design. In conjunction with these services, Sierra offers experienced on-site drilling supervision services. Sierra provides its clients the expertise necessary to develop, evaluate, and execute projects ranging from a single well to entire fields. Sierra has no vested interest in selling products or services, and has no equity position in oil or gas ventures. Sierra’s primary objective is to construct producing wellbores at optimized cost.
Sierra Engineering primarily operates in the continental U.S. Sierra has also provided services in South America, Yemen, the UK, and Russia. Sierra serves energy companies that are seeking to reduce operating costs while still managing active wellbore construction programs. Sierra’s flexible manpower capacity allows operators to supplement and buffer their engineering and field supervision staffs during peak levels of activity.
Sierra Engineering has proven itself to be a “low-cost operator” in
East Texas, Four-Corners, Oklahoma, and the Permian Basin. Sierra
has established a reputation for providing low-cost, high-value
drilling and completion engineering as well as field supervision
services. Sierra differentiates itself from its competitors by
offering a wide range of these services required to drill and complete
wellbores. Sierra provides additional value through state-of-the-art
completion design, hydraulic fracturing execution, and post-frac
evaluation services.
