SPE 170393Addressing Safety Challenges of Operating in Sour

Gas Fields: A Case Study from the Middle East

Anthony Onerhime, Schlumberger, Andy Kveps and Elie Daher, United Safety

The Challenge of Sour GasSlide 2

Prevent exposure by implementing:•Mechanical and procedural measures •Early warning detection and notification systems•Breathing protection measures for personnel in the event of a release

Hydrogen sulfide attacks the respiratory and central nervous systems of the victim, resulting in death at about 1000 ppm. Oil and gas projects in the Middle East can encounter H2S up to 400,000 ppm.
