Related Parties
We and ConocoPhillips, one of our principal owners, are parties to a long-term water gathering and handling agreement, pursuant to which ConocoPhillips dedicates all the produced water generated from its current and future acreage in a defined area of mutual interest in New Mexico and Texas.
As of June 30, 2024 and December 31, 2023, we had receivables of $29.1 million and $23.0 million, respectively, from ConocoPhillips that were recorded in “Accounts Receivable from Affiliate” on the condensed consolidated balance sheet. As of June 30, 2024 and December 31, 2023, we had payables of $0.7 million and $0.9 million, respectively, to ConocoPhillips that were recorded in “Payables to Affiliate” on the condensed consolidated balance sheet. Revenues related to ConocoPhillips were $32.0 million and $64.1 million, respectively, for the three and six months ended June 30, 2024. Revenues related to ConocoPhillips were $31.3 million and $62.5 million, respectively, for the three and six months ended June 30, 2023.
Collaborative Arrangements
We have a beneficial reuse strategic agreement (the “Joint Industry Project” or “JIP”) with Chevron U.S.A. Inc., ConocoPhillips and Exxon Mobil Corporation (collectively with us, the “alliance members”) to develop and pilot technologies and processes to treat produced water for potential beneficial reuse opportunities. We previously referred to this agreement as the Beneficial Reuse Strategic Agreement. We account for reimbursements of research and development costs under the JIP as contra-expenses in the period such expenses are incurred. This reflects the joint risk sharing nature of these activities within the collaborative arrangement. We classify advance billings or receivables recorded as “Accrued and Other Current Liabilities” or “Other Receivables,” respectively, on our condensed consolidated balance sheet.
For the three and six months ended June 30, 2024, we incurred $2.6 million and $5.2 million, respectively, in total research and development expenses relating to the JIP, which was offset by $1.9 million and $3.9 million, respectively, in amounts due from the other alliance members for reimbursement of these shared costs. For the three and six months ended June 30, 2023, we incurred $2.0 million and $2.1 million, respectively, in total research and development expenses relating to the JIP, which was offset by $1.5 million and $1.6 million, respectively, in amounts due from the other alliance members for reimbursement of these shared costs.
Recent Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this ASU primarily relate to the rate reconciliation and income taxes paid disclosures and improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. This ASU is effective for annual periods beginning after December 15, 2024 and may be applied prospectively or retrospectively. Other than the required disclosures, we do not expect a material impact on our condensed consolidated financial statements and related disclosures upon adoption.
In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this ASU require disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. This ASU is effective for annual periods beginning after December 15, 2024 and should be applied prospectively. Other than the required disclosures,
