Revenues

Revenues are generated upon the performance of contracted services under formal and informal contracts with customers. Revenues are recognized when the contracted services for our customers are completed in an amount that reflects the consideration we expect to be entitled to in exchange for those services. Sales and usage-based taxes are excluded from revenues. Payment is due when the contracted services are completed in accordance with the payment terms established with each customer prior to providing any services. As such, there is no significant financing component for any of our revenues.

Some of our contracts with customers involve multiple performance obligations as we are providing more than one service under the same contract, such as water transfer services and disposal services. However, our core service offerings are capable of being distinct and also are distinct within the context of contracts with our customers. As such, these services represent separate performance obligations when included in a single contract. We have standalone pricing for all of our services which is negotiated with each of our customers in advance of providing the service. The contract consideration is allocated to the individual performance obligations based upon the standalone selling price of each service, and no discount is offered for a bundled services offering.

Water Transfer Services

The majority of our revenues are from the removal and disposal of flowback and produced saltwater originating from oil and natural gas wells or the transportation of fresh water and saltwater to customer sites for use in drilling and hydraulic fracturing activities by trucks or through lay flat temporary hose or permanent water transport pipelines. Water transfer rates for trucking are based upon either a fixed fee per barrel of disposal water or upon an hourly rate. Revenue is recognized once the water has been transferred, or over time, based upon the number of barrels transported or disposed of, or at the agreed upon hourly rate, depending upon the customer contract. Contracts for the use of our disposal water pipeline are priced at a fixed fee per disposal barrel transferred, with revenues recognized over time from when the water is injected into our pipeline until the transfer is complete. Water transfer services are all generally completed within 24 hours with no remaining performance obligation outstanding at the end of each month.

Disposal Services

Revenues for disposal services are generated through fees charged for disposal of oilfield wastes in our landfill and disposal of fluids in our disposal wells. Disposal rates are generally based on a fixed fee per barrel of disposal water, or on a per ton basis for landfill disposal, with revenues recognized once the disposal has occurred. The performance obligation for disposal services is considered complete once the disposal occurs. Therefore, disposal services revenues are recognized at a point in time.

Other Revenue

Other revenue primarily includes revenues from the sale of fresh water, as well as the sale of “junk” or “slop” oil obtained through the skimming of disposal water. Revenue is recognized for fresh water sales and “junk” or “slop” oil sales at a point in time once the goods are transferred. Also included is revenue generated by oilfield labor services, often times called “roustabout work,” provided by the Company. Revenue is recognized in other revenue for the oilfield labor services once the activity has been performed, or over time, based on the agreed upon hourly rate, depending upon the customer contract. Oilfield labor services are short-term in nature with hours tracked each day services are provided. As such, there are no remaining performance obligations outstanding at the end of each month.

Other revenue also historically included small-scale construction or maintenance projects, however we exited that business during the three months ended June 30, 2018. Revenue for construction and maintenance projects, which generally spanned approximately two to three months, was recognized over time under the milestone method which is considered an output method. Since our construction contracts were short term in nature, the contractual milestone dates occurred close together over time such that there was no risk that we would not recognize revenue for goods or services transferred to the customer. All construction costs were expensed as incurred.

Rental Revenue

We generate rental revenue from the rental of various equipment used in wellsite services. Rental rates are based upon negotiated rates with our customers and revenue is recognized over the rental service period. Revenues from rental equipment are recognized under ASC 840 for the periods prior to January 1, 2019, and under ASC 842 for the periods after January 1, 2019. As the rental service period for our equipment is very short term in nature and does not include any sales-type or direct financing leases, nor any variable rental components, the adoption of ASC 842 in 2019 did not have a material impact upon our consolidated statement of operations.
