Data, Analytics, and Ratings for Oil and Gas Wastes

The leadership at Waste Analytics has more than 25 years of waste management and environmental experience in the oil and gas industry. We gather and provide information regarding upstream oil and gas wastes, all based on GRI standards. Our data includes the type and volume of wastes generated, the disposal methods used, and our FEER Rating™, which can be used to compare and contrast the waste management practices, and potential liabilities, of oil and gas companies.

FEER Rating™

The Waste Analytics FEER Rating™ provides an easy way for investors to compare and contrast the waste management performance of oil and gas companies. We developed the rating system to take into account both the economic and environmental aspects of drilling wastes so that investors can glean insight into how a company is managing waste in relation to the EPA Waste Management Hierarchy, as well as how their Estimated Environmental Liability (EEL) compares to their financial standing.


Most oil and gas companies disclose in their 10-K filings that changes to regulations surrounding drilling wastes could have a material adverse effect on their business and prospects but don’t disclose to what degree. Utilizing our extensive experience in managing drilling wastes, along with standard methods for calculating monetary costs and liabilities for environmental matters, we have calculated the Estimated Environmental Liability (EEL) for each company’s drilling wastes, based on the amount of waste generated and the chosen disposal method in a given year. This information can be useful when assessing the risk of a particular investment.


The Global Reporting Initiative recommends that companies report on their wastes by type and disposal method; yet most oil and gas companies do not track or provide this information to investors. Waste Analytics compiles information through various sources and derives this information. We report the volumes of drilling waste generated by each company, the type of drilling waste, and the disposal methods used. This information is comparable across the sector.

Drilling Wastes Rival Coal Ash in Volume

All oil and gas wells that are drilled generate drilling wastes. An estimated 392,000,000 barrels of drilling wastes were generated in 2014 alone in the United States. This volume of waste rivals that of coal ash. Like E&P wastes, coal ash was also exempt from federal hazardous waste rules; however, additional guidance and limits were ultimately placed on the proper disposal and reuse of coal ash, while drilling wastes remain under the radar.

Drilling Wastes Pose Significant Environmental and Economic Risk

Drilling wastes often contain various chemicals of potential concern, and can be a significant component of an operator's well cost and liability. Although most oil and gas companies are managing their drilling wastes according to applicable regulations, there is still potential for contamination to occur. Common constituents in drilling wastes include salts, heavy metals, and hydrocarbons, along with other proprietary chemicals.

There Are No Minimum National Standards For The Management of Drilling Wastes

E&P wastes are exempt from federal hazardous waste rules, and are therefore regulated by each state. There are currently no minimum national standards for the disposal of E&P wastes. The United States EPA has a statutory duty to review E&P wastes every three years and, if necessary, draft new rules or guidelines; however, they have not done so since 1988. In 2016, EPA was sued by multiple ENGOs and entered into a consent decree to determine whether new rules for E&P wastes are warranted.
