IFP SCHOOL . THE GRADUATE SCHOOL FOR ENERGY AND TRANSPORTATION PROFESSIONS. What are the main steps of an oil or gas field development project? A. hydrocarbon field has a long life cycle: From the discovery of a petroleum deposit to the first oil/gas, exploration and production activities are spread over several decades. Five main steps can be distinguished in the life of an oil or gas field : The production facilities design The amount of and reserves? implementation Oil and gas Where is production Site the field ? restitution 1 2 3 4 5.
