Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Organization We are a growth oriented master limited partnership focused on the midstream segment of the crude oil and natural gas industry in the Gulf Coast region of the United States, Wyoming and the Gulf of Mexico. We have a diverse portfolio of assets, including pipelines, refinery-related plants, storage tanks and terminals, railcars, rail loading and unloading facilities, trucks, barges and a product tanker. We were formed in 1996 and are owned 100% by our limited partners. Genesis Energy, LLC, our general partner, is a wholly-owned subsidiary. Our general partner has sole responsibility for conducting our business and managing our operations. We conduct our operations and own our operating assets through our subsidiaries and joint ventures. In the fourth quarter of 2016, we reorganized our operating segments as a result of the way our Chief Executive Officer, who is our chief operating decision maker, evaluates the performance of operations, develops strategy and allocates resources. The results of our onshore pipeline transportation segment, formerly reported under its own segment, are now reported in our supply and logistics segment. This change is consistent with the increasingly integrated nature of our onshore operations. As a result of the above changes, we currently manage our businesses through four divisions that constitute our reportable segments - offshore pipeline transportation, refinery services, marine transportation, and supply and logistics. Our disclosures related to prior periods have been recast to reflect our reorganized segments. These four divisions that constitute our reportable segments consist of the following:
• | Offshore pipeline transportation and processing of crude oil and natural gas in the Gulf of Mexico;
• | Refinery services involving processing of high sulfur (or “sour”) gas streams for refineries to remove the sulfur, and selling the related by-product, sodium hydrosulfide (or “NaHS”, commonly pronounced “nash”);
• | Marine transportation to provide waterborne transportation of petroleum products and crude oil throughout North America; and
• | Supply and logistics services, which include terminaling, blending, storing, marketing, and transporting crude oil, petroleum products, and CO2.
