Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Organization and Operations NGL Energy Partners LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware master limited partnership. NGL Energy Holdings LLC serves as our general partner (“GP”). At September 30, 2025, our operations included three segments: •Our Water Solutions segment transports, treats, recycles and disposes of produced and flowback water generated from crude oil and natural gas production. We also sell produced water for reuse and recycle to our producer customers to be used in their crude oil exploration and production activities. As part of processing water, we aggregate and sell recovered crude oil, also known as skim oil. We also dispose of solids such as tank bottoms, drilling fluids and drilling muds and perform other ancillary services such as truck washouts. Our activities in this segment are underpinned by long-term, fixed fee contracts and acreage dedications, some of which contain minimum volume commitments with leading oil and gas companies including large, investment grade producer customers. •Our Crude Oil Logistics segment purchases crude oil from producers and marketers and transports it to refineries or for resale at pipeline injection stations, storage terminals, barge loading facilities, rail facilities and other trade hubs, and provides storage, terminaling, and transportation services through its owned assets. Our activities in this segment are supported by certain long-term, fixed rate contracts with acreage dedications and which include minimum volume commitments on our storage tanks and owned and leased pipelines. •Our Liquids Logistics segment conducts supply operations for natural gas liquids to commercial, retail and industrial customers across the United States and Canada. These operations are conducted through our five owned terminals, third-party storage and terminal facilities, access to nine common carrier pipelines and a fleet of leased railcars. We also provide services for marine exports of butane through our facility located in Chesapeake, Virginia and we also own a propane pipeline in Michigan. We attempt to reduce our exposure to price fluctuations by using back-to-back physical contracts and pre-sale agreements that allow us to lock in a margin on a percentage of our winter volumes. We also enter into financially settled derivative contracts as economic hedges of our physical inventory, physical sales and physical purchase contracts. Discontinued Operations Sale of Refined Products Business and Exiting Biodiesel Business As of March 31, 2025, we completed winding down our biodiesel business. On April 30, 2025, we sold our refined products business, including certain working capital items, to a third-party (see Note 15 for a further discussion). The sale of our refined products business and winding down of our biodiesel business represent a strategic shift in our operations and will have a significant effect on our operations and financial results going forward. Accordingly, the results of operations and cash flows for our refined products and biodiesel businesses within our Liquids Logistics segment have been classified as discontinued operations for all periods presented and prior periods have been retrospectively adjusted in the unaudited condensed consolidated statements of operations and unaudited condensed consolidated statements of cash flows. In addition, the assets and liabilities related to our refined products and biodiesel businesses were classified as either held for sale or discontinued operations within our September 30, 2025 and March 31, 2025 unaudited condensed consolidated balance sheets (see Note 16 for a further discussion). Other Dispositions Sale of Certain Investments in Unconsolidated Entities and Related Assets On April 14, 2025, we sold certain investments in unconsolidated entities, property, plant and equipment and intangible assets to a third-party, which were classified as held for sale within our March 31, 2025 consolidated balance sheet (see Note 15 for a further discussion). Sale of Certain Natural Gas Liquids Terminals and Most of Our Wholesale Propane Business On April 30, 2025, we sold most of our wholesale propane business, 17 of our natural gas liquids terminals, our interest in an unconsolidated entity and working capital (“Wholesale Propane Disposition”) to a third-party (see Note 15 for a further discussion). The assets and liabilities of this portion of our Liquids Logistics segment were classified as held for sale within our March 31, 2025 consolidated balance sheet (see Note 16 for a further discussion). Sale of Certain Railcars As of March 31, 2025, we entered into definitive agreements with third-parties to sell certain railcars, which have been classified as held for sale within our March 31, 2025 unaudited condensed consolidated balance sheet (see Note 15 for a further discussion).
