SPE-174441 Reservoir Simulation of H2S Production During a SAGD Process Using a new Sulfur-Based-Compositional Kinetic Model to be presented at 2015 SPE Canada Heavy Oil Technical Conference on June 11

Nowadays steam injection is commonly used as a thermal EOR method. However this process is also associated with chemical reactions in the reservoirs, called aquathermolysis, which produce the highly toxic and corrosive acid gas H2S in the presence of sulfur-rich heavy oil.

The overall objective of this work is to understand the aquathermolysis reactions in reservoirs undergoing steam injections and provide Oil companies with a numerical model for reservoir simulators that forecasts H2S production risk.
