The “Pre-salt application” offers some unique and challenging difficulties for producers and the service companies who support their operations. The carbonate reservoirs which occur in Brazilian deepwater fields provide unique challenges that relate to high temperatures, the high H2S content, as well as severe saline and scaling conditions. It is quite common to find oil and gas fields with estimated H2S level in the produced gas between 100 and 200 ppmv and salinity approximately 230,000 mg/L. Hydrogen sulfide is a poisonous gas, very harmful to life, and removal is essential to comply with sulfur emissions, as well as to ensure system and pipeline integrity.
