Geological and Geophysical (G&G) Surveys Fact Sheet
G&G surveys are conducted to: (1) obtain data for oil and gas (O&G) exploration and production, (2) aid in siting offshore (i.e., O&G, renewable energy) structures, and (3) locate marine mineral resources. More specifically, G&G surveys are necessary to make informed decisions about O&G resources, engineering decisions regarding the construction of offshore projects, and informed estimates regarding the composition and volume of sand and gravel resources. Such data are also used to ensure the proper use and conservation of Outer Continental Shelf (OCS) energy resources and the receipt of fair market value for the leasing of public lands.
