Waste liquid management in heavy oil operations

This SPE article explores the current state of heavy oil and bitumen waste management practices.

In addition to managing GHG impact through the sequestration and reuse of CO2 from heavy oil operations, there is considerable industry focus on improving the management of waste liquids associated with the production of heavy crude oil. Large volumes of surface water are needed to produce, transport, and upgrade heavy crude oils. Produced and process waters often contain high concentrations of salts, metals, hydrocarbons, and acids that may cause environmental damage if discharged untreated to surface waters or soils.

A contemporary reference on the subject is SPE Paper 101973,Environmental Challenges of Heavy Crude Oils: Management of Liquid Wastes, which was presented at the March 5^th- 7^th E&P Environmental and Safety Conference in Galveston. It summarizes current management practices and technology for waste waters associated with heavy crude oil production and upgrading.

Economically reducing the environmental impact of heavy oil operations will continue to be a key theme for our industry and an important planning consideration for any heavy oil or bitumen operation.
