Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract] |
SEGMENTS | SEGMENTS Segment Descriptions - Our operations are divided into three reportable business segments, as follows: •our Natural Gas Gathering and Processing segment gathers, treats and processes natural gas; •our Natural Gas Liquids segment gathers, treats, fractionates and transports NGLs and stores, markets and distributes NGL products; and •our Natural Gas Pipelines segment transports and stores natural gas via regulated intrastate and interstate natural gas transmission pipelines and natural gas storage facilities. Other and eliminations consist of corporate costs, the operating and leasing activities of our headquarters building and related parking facility and eliminations necessary to reconcile our reportable segments to our Consolidated Financial Statements. For the year ended December 31, 2021, revenues from one customer in our Natural Gas Liquids segment represents approximately 11.6% of our consolidated revenues. For the years ended December 31, 2020 and 2019, we had no single customer from which we received 10% or more of our consolidated revenues. Operating Segment Information - The following tables set forth certain selected financial information for our operating segments for the periods indicated:
