FactoryRegistry lists 731 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced oil and gas field derricks, substructures and accessories, including well-surveying machinery and equipment and well-logging equipment, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
