Produced fluids, from a number of wells completed in a sour reservoir in a giant field in Kuwait contain varying concentrations of H2S, with levels ranging from 1% (10,000 ppm) to 3% (30,000 ppm).

This souring problem made the concerned reservoir undeveloped fully for many years since there are currently no adequate surface facilities and system in place to handle such high amount of H2S.

In order to dynamically mitigate these challenges, a pilot trial of an innovative technology was considered in one of the wells within this field, which has 1.3% (13,000 ppm) H2S concentration. The outcome from this pilot was very encouraging and promising as the H2S level was reduced to the expected set level on a fully automated basis.

This paper highlights the screening process for candidate selection, technical design considerations, KOC-HSE regulations and the successful implementation of this new system on a single well basis and also the lessons learned from the full collaboration between the project team and service provider.
