Steam Flood Souring Simulator

Steam Flood Souring Simulator Project

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

GOALS

This is a Research & Development project whose objective is to develop simulation software capable of quantitatively predicting the generation and production of H2S associated with the injection of water vapor.

SOLUTIONS

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

SourSimRL, a project developed by ESSS in partnership with Oil Plus, simulates the generation of H2S associated with the activity of sulfate reducing bacteria present in the reservoir. This microbiological action occurs due to the injection of water, usually sea water. The Steam Flood Souring simulator, however, focuses on the simulation of 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 of the benefits of the Steam Flood Souring Simulator project are described below:

  • Increased personnel safety when producing toxic gas;
  • Reduction of the impact of corrosion of production equipment in general by hydrogen sulphide;
  • Reduction of probable H2S removal requirements to meet oil and gas export specifications.
