Well Control – H2S

Well Control - H2S

During drilling and workover operations the consequences of leaks or kicks with sour gas or crude may be very serious. Personnel can be incapacitated by relatively low concentrations of H2S in a very short time and equipment can suffer catastrophic failure due to H2S embrittlement.

The H2S risk depends primarily on the H2S content of the formation fluids, the formation pressure, and the production flow rate. This information is used to assess the level of danger that H2S presents and the requirement for special equipment, layout, and emergency procedures for the drilling or workover . . .
