Solution gas, a gas containing primarily methane, is produced during the extraction of oil from reservoirs across Alberta. At present, about 92% of the solution gas is collected for processing and the remainder is flared. In recent years, there has been a growing concern over solution gas flaring because of the potential health effects of bi-products of incomplete combustion from the process. Reduction of gas flaring is seen as a logical approach to this problem. This paper provides a critical analysis of the solution gas flaring situation in Alberta. Potential technological alternatives available to reduce flaring are presented. The study addresses the potential improvements which are achievable with the following technologies: Collection in a low-pressure gas system, electrical generation with gas turbines, electrical generation with 'mini' turbines, cogeneration, co-disposal with produced water, and oxidation. The study has found that electrical generation could economically reduce flare gas emissions in the province. Co-disposal with produced water has the potential to reduce emissions at a reasonable cost at sites where a produced water disposal well already exists. Collection of gas in a low-pressure gas system has the potential to gather gas from several sites in close proximity to allow sufficient gas volumes to proceed with electrical generation or other end uses. Cogeneration has little potential as an electrical demand, a need for steam, and sufficient quantities of waste gas are all required at the same site. Oxidation, both biological and physical have not yet advanced to the point where they are proven technologies in the oil and gas industry.
