Related Party Transactions [Abstract] |
Related Party Transactions | Note 4. Related Party Transactions Commercial Agreements Effective January 1, 2014, we entered into long-term fee-based (i) gas gathering, (ii) crude oil gathering, (iii) gas processing and fractionation, (iv) storage services, and (v) terminal and export services agreements with certain subsidiaries of Hess. Effective January 1, 2019, in connection with the Hess Water Services Acquisition, we entered into long-term fee-based water services agreements with certain subsidiaries of Hess. Under our commercial agreements, we provide gathering, compression, processing, fractionation, storage, terminaling, loading, transportation and produced water disposal services to Hess, for which we receive a fee per barrel of crude oil, barrel of water, Mcf of natural gas, or Mcf equivalent of NGLs, as applicable, delivered during each month, and Hess is obligated to provide us with minimum volumes of crude oil, water, natural gas and NGLs. These agreements also include inflation escalators and fee recalculation mechanisms that allow fees to be adjusted annually. For the three and six months ended June 30, 2020 and 2019, approximately 100% of our revenues were attributable to our fee‑based commercial agreements with Hess, including revenues from third‑party volumes contracted with Hess and delivered to us under these agreements. We retain control of our assets and the flow of volumes based on available capacity within our integrated gathering, processing and terminaling systems. Together with Hess, we are pursuing strategic relationships with third‑party producers and other midstream companies with operations in the Bakken in order to maximize our utilization rates. Revenues from contracts with customers on a disaggregated basis are as follows:
