6 Months Ended

Jun. 30, 2019

The Company’s exploration and production segment is engaged in the acquisition and development of oil and natural gas properties. Revenues for the exploration and production segment are derived from the sale of crude oil and natural gas production. The Company’s midstream services business segment performs produced and flowback water gathering and disposal services, fresh water services, natural gas gathering and processing and crude oil gathering and transportation and other midstream services for crude oil and natural gas wells operated by the Company as well as third-party operated wells. Revenues for the midstream segment are primarily derived from produced and flowback water pipeline transport, produced and flowback water disposal, fresh water sales, natural gas gathering and processing and crude oil gathering, blending, stabilization and transportation. The Company’s well services business segment performs completion services for the Company’s crude oil and natural gas wells. Revenues for the well services segment are derived from providing well services, product sales and equipment rentals. The revenues and expenses related to work performed by OMP, OMS and OWS for the Company's ownership interests are eliminated in consolidation, and only the revenues and expenses related to non-affiliated working interest owners are included in the Company’s Condensed Consolidated Statements of Operations. These segments represent the Company’s three operating units, each offering different products and services. The Company’s corporate activities have been allocated to the supported business segments accordingly.

Management evaluates the performance of the Company’s business segments based on operating income, which is defined as segment operating revenues less operating expenses, including depreciation, depletion and amortization (“DD&A”).

For the three and six months ended June 30, 2018, the Company has revised the condensed consolidated financial statements and business segment financial information to reflect the correction of errors related to the manner in which it accounted for certain crude oil purchase and sale arrangements, which are included in the Company’s exploration and production segment and had no effect on operating income. Please see Note 2 — Summary of Significant Accounting Policies for more information related to the revision.

The following table summarizes financial information for the Company’s three business segments for the periods presented:
