Long-Term Debt, Unclassified [Abstract]  
Long-term Debt [Text Block] LONG-TERM DEBTSenior Notes - On August 8, 2022, ONE Gas issued $300 million of 4.25 percent senior notes due 2032. The proceeds from the issuance were used to repay amounts outstanding under our commercial paper program and for general corporate purposes.
In March 2021, we issued $1.0 billion of 0.85 percent senior notes due March 2023, $700 million of 1.10 percent senior notes due March 2024, and $800 million of floating-rate senior notes due March 2023. The net proceeds from the issuance were used for payment of gas purchases and related costs resulting from Winter Storm Uri and general corporate purposes.

In September 2021, we called $400 million of the floating-rate senior notes due March 2023 at par, using a combination of cash on hand and commercial paper. We did not have the right to call these senior notes prior to September 11, 2021.

On August 25, 2022, we called $750 million of the $1.0 billion of 0.85 percent senior notes due March 2023, $150 million of the $700 million of 1.10 percent senior notes due March 2024 and the remaining $400 million of outstanding floating-rate senior notes due March 2023, using the proceeds received from the securitization transaction for Oklahoma Natural Gas. See Note 3 of the Notes to Consolidated Financial Statements in this Quarterly Report for additional discussion of the securitization transaction. We expect to use the proceeds from the issuance of securitized bonds in Kansas and Texas, as discussed in Note 3, to call the outstanding senior notes due March 2023 and a portion of the senior notes due March 2024.

The indenture governing our Senior Notes includes an event of default upon the acceleration of other indebtedness of $100 million or more. Such events of default would entitle the trustee or the holders of 25 percent in aggregate principal amount of the outstanding Senior Notes to declare those Senior Notes immediately due and payable in full.

ONE Gas 2021 Term Loan Facility - In February 2021, we entered into the ONE Gas 2021 Term Loan Facility as part of the financing of our natural gas purchases in order to provide sufficient liquidity to satisfy our obligations as a result of Winter Storm Uri. The net proceeds of the March 2021 debt issuance reduced the commitments under the ONE Gas 2021 Term Loan Facility on a dollar-for-dollar basis, and as a result no commitments remained outstanding and the facility was terminated concurrently with the closing of the debt issuance.
