Casto Petroleum Engineering is an oil and gas consulting firm in Marietta, Ohio. Specializing in the Appalachian basin, I evaluate the Marcellus and Utica shale plays as well as conventional reservoirs in the region. I provide all the services you expect from a consultant, but these aren't just commodities to be pulled off the shelf. My approach to every project is to get to know the client, clarify their issues, then create a custom strategy to achieve their goals, without wasting time or money.
