A Review of Sulphide Scavengers in Oil and Gas Industry

The application of sulphide scavengers is an adopted practice which is widely in production and processing operations in the Oil and Gas Industry. Challenge is the search and development of new chemistries, which is aimed at safeguarding the health of personnel and maintaining good protection of materials under a variety of conditions while being environmentally acceptable. This paper includes an up to date history of the efforts which have been put forth so far in the industry to minimize or eliminate the various problems caused by hydrogen sulphide during Oil and Gas drilling operations by the use of some chemicals. The advantages and disadvantages of using the various chemicals for scavenging hydrogen sulphide drilling fluids and produced fluids are compared.
