Abstract: The Geochemistry and Environmental Control of Mercury and Arsenic in Gas, Condensate, and Water Produced in the Gulf of Thailand

Summary

Gas and condensate produced in the Gulf of Thailand are contaminated with mercury and arsenic. The mercury is thought to originate in coal and carbonaceous shale in or near the producing reservoirs Water co-produced with the hydrocarbons is contaminated both with stabilized emulsions and with the heavy metals. Using physical chemical characterization data, a process was designed and tested at a pilot scale to remove contaminants from the produced water. The data and experience from the successful pilot tests were then used to design and engineer full-scale water cleaning facilities. The first three installations for the process are scheduled to become operational in late 1997.
