Surface and Downhole Production Safety Systems for Sour Oil and Gas Wells

Abstract

ABSTRACT The work on sour gas and oil wells by its nature is dangerous. Highly flamable and toxic sour gas and fluids under high pressure need to be handled by special equipment in a hostile environment. Within ADCO, safety systems have been developed to protect the large investment, the environment and safety of operating personnel. As a result of the high pressure and sour production involved, it is necessary to incorporate high – strength tubular materials and safety features such as surface controlled sub-surface safety valves, kill/dump valves, downhole packers and chemical injection systems into the completion design. Several types of surface and sub-surface systems have been reviewed and tested for use in our onshore sour gas and oil wells in Abu Dhabi.
