Steam Flood Souring Simulator

Simulator to predict the generation and production of H2S associated with the injection of water vapor

Steam Flood Souring Simulator

Goals

Our Steam Flood Souring Simulator is an R&D project designed to predict H2S generation associated with water vapor injections.

Solutions

Injection of water vapor into reservoirs is an Enhanced Oil Recovery (EOR) process, but it can generate large quantities of undesirable products, such as hydrogen sulphide (H2S) in a process called souring. H2S can cause aggressive corrosion and health and environmental safety issues, so these problems must be minimized or mitigated.

SourSimRL simulates H2S generation in waterflooded reservoirs due to the activity of Sulfate Reducing Bacteria (SRB) that are present in the reservoir. The Steam Flood Souring simulator focuses on H2S generation by thermolysis (or thermal decomposition) of heavy oil – more specifically, the thermolysis in an aqueous environment produced by the injection of water vapor.

Benefits

Some benefits of the Steam Flood Souring Simulator project are:

  • Increased personnel safety when producing toxic gas
  • Reduced impact on l production equipment corrosion by hydrogen sulphide
  • Fewer H2S removal requirements may be needed in order to meet oil and gas export specifications
