New DNV GL JIP to deal with risks in sour gas fields

ABU DHABI -- In the operation and development of a sour gas field, a key challenge is ensuring the process safety and integrity of the asset and, most importantly, the safety of the personnel working with high concentrations of hydrogen sulphide (H2S). To help the industry manage risks throughout the project’s lifecycle, DNV GL has now initiated a Joint Industry Project (JIP) for operators.

Several sour gas fields are under development, or in operation, in different parts of the world. The focus is now on the Middle East, as this region looks likely to meet its soaring domestic energy demand through its large reserves. However, sour gas is toxic, highly corrosive and explosive, so both the development and operation of these fields are associated with a high risk level relating to health, safety and the environment (HSE), process safety and integrity.

As a driver for this JIP, DNV GL analyzed all the available standards, procedures and current practices. Gaps were identified and revealed that the available standards were not adequate to effectively manage the H2S hazards.

The JIP will run for six months and will include contributions from major international and national oil companies working with sour gas. In addition, DNV GL, the initiator and manager of the project, will contribute its own expertise. The conclusions will be presented in a set of guidelines available to the industry.
