2016-2017 Corporate Responsibility

Waste Management

Drill cuttings, which consist of ground rock and residual drilling fluids, are generated in the form of by-products from our operations. As part of our focus on waste reduction, we actively explore and implement methods to minimize waste through a beneficial use program.

Areas where drill cuttings can be reused are: construction materials in road pavements, bitumen and asphalt or use in concrete or cement manufacturing.

We selected third-party waste management facilities for voluntary audits in 2016 based on current disposal volumes and our future outlook for production fluids and drilling solids disposal. The audit results helped us select vendors with practices that best align with our standards, who have the ability to safely and responsibly handle larger volumes of waste and with a focus on material recycling for beneficial use.


Naturally Occurring Radioactive Materials (NORM)

Naturally occurring radioactive material (NORM) can be brought to the surface with produced water during oil and gas operations, and may accumulate on equipment. In accordance with regulatory requirements and our own NORM Management Program, employees and contractors are trained and certified annually to understand which of our operations, locations and equipment are associated with NORM exposure. Currently, production water radiation levels in our operations in North Dakota, Oklahoma and Utah are at background or are marginally detectable. Our protocols in these same areas of operations focus on management of NORM contaminated equipment including the proper procedures to work safely around NORM. In our training, we emphasize utilization of personal protective equipment and how to detect, handle, store, transport and dispose of NORM. In 2016, surveyor training was conducted for personnel who inspect for NORM in all operational field offices, and 90 people participated. This training is offered annually, and employees are required to receive NORM surveyor training once every two years.

In addition to awareness training, in 2016 we completed 330 surveys on NORM waste and NORM-impacted equipment, and safely disposed of 570 barrels of NORM waste.

In 2017, we initiated improved tracking efforts for NORM waste and conducted baseline NORM surveys on our facilities and equipment. Baseline data will allow us to track the concentration of NORM over time and ensure that levels continue to remain low.

2016 Highlights

Proactively utilized 7,420 cubic yards of drill cuttings for well pad construction materials.


Used closed-loop systems for the management and reuse of drilling residuals on 95 percent of wells drilled across our operations—decreasing reliance on reserve pits.


Successfully completed voluntary compliance audits at 10 percent of the third-party waste management facilities utilized in our operations.


2017 Updates

Initiated small pilot project in Oklahoma with a third-party vendor on new thermal desorption technology to extract and sell hydrocarbons from drill cuttings with use of the remaining material for pad and road building.
