Derivative Instruments and Hedging Activities Disclosure [Abstract]  
RISK-MANAGEMENT AND HEDGING ACTIVITIES USING DERIVATIVES RISK-MANAGEMENT AND HEDGING ACTIVITIES USING DERIVATIVES
Risk-management Activities - We are sensitive to changes in the prices of natural gas, NGLs, Refined Products and crude oil, principally as a result of contractual terms under which these commodities are processed, purchased and sold. We are also subject to the risk of interest-rate fluctuation in the normal course of business. We use physical-forward purchases and sales and financial derivatives to secure a certain price for a portion of our natural gas, NGLs, Refined Products, condensate and crude oil purchases and sales; to reduce our exposure to commodity price and interest-rate fluctuations; and to achieve more predictable cash flows. Additionally, we may use physical-forward purchases and financial derivatives to reduce commodity price risk associated with power and natural gas used to operate our facilities. We follow established policies and procedures to assess risk and approve, monitor and report our risk-management activities. We have not used these instruments for trading purposes.

Commodity price risk - Commodity price risk refers to the risk of loss in cash flows and future earnings arising from adverse changes in the price of natural gas, NGLs, Refined Products and crude oil. We may use commodity derivative instruments to reduce the near-term commodity price risk associated with a portion of our forecasted purchases and sales of commodities. Our exposure to commodity price risk is consistent with that discussed in our Annual Report.

Interest-rate risk - We may manage interest-rate risk through the use of fixed-rate debt, floating-rate debt, Treasury locks and interest-rate swaps. At June 30, 2026, and December 31, 2025, we had no outstanding interest-rate derivative instruments.

Cash Flow Hedges - At June 30, 2026, and December 31, 2025, the accumulated other comprehensive income (loss) relating to risk-management assets and liabilities, net of taxes, was $17 million and $19 million, respectively. Corresponding unrealized gains (losses) related to risk-management assets and liabilities at June 30, 2026, and December 31, 2025, were not material.

For the three and six months ended June 30, 2026, the unrealized change in fair value of cash flow hedges in other comprehensive income (loss) related to commodity contracts was $23 million and $(371) million, respectively.

The following table sets forth the effect of cash flow hedges on net income for the periods indicated:

Credit Risk - We monitor the creditworthiness of our counterparties and compliance with policies and limits established by our Risk Oversight and Strategy Committee. We maintain credit policies with regard to our counterparties that we believe minimize credit risk. Our policies and related credit risk are consistent with those discussed in our Annual Report.
