Drill-Cuttings Treatment Alternatives—A Comparative Emissions Assessment

The study assessed the CO2 footprint and NO2 emissions for different drill-cuttings treatment alternatives. The values were then used to create an emissions calculator that can be applied to projects to clarify the actual potential for emissions reduction within the drilling-waste-management process.

The offshore oil and gas industry has always been cognizant of its impact on the marine environment. The choices that operators make in how they operate, including the disposal of drill cuttings, must address an increasing number of environmental and climate targets in addition to those related to health, safety, and cost. As a typical well will produce approximately 1000 metric tons of oil-based drill cuttings, quantifying greenhouse-gas (GHG) emissions associated with the disposal and treatment of drill cuttings has become an essential step to achieving net-zero ambitions.
