Both are part of oil and gas regions

Oil and gas regions refer to areas where oil reserves and natural gas reserves are concentrated. These areas may be located on land or offshore. Oil and gas regions typically contain large concentrations of oil and gas reserves, which can be found in sedimentary basins, offshore basins, and other areas that are conducive to oil and gas exploration and production. The areas may be characterized by a variety of geological features, including low permeability rocks, tight resources, unconventional deposits, and aging infrastructure. Oil and gas regions are often characterized by relatively large concentrations of activity from exploration and production companies and service companies, such as drilling and completion contractors, engineering firms, and other entities.
