To date RESL has completed decommissioning work on over 870 facilities, more than 1,876 well P&A’s, numerous pipelines and subsea systems, over 22 FPSO & FSO facilities, over 40 onshore facilities for most of the major oil & gas companies worldwide. RESL has worked for major oil and gas operators around the world, including Australia, UK, Norway, Netherlands, Greece, Canada, Gulf of Mexico, Japan, Indonesia, India, South Africa, Thailand, Tanzania, Nigeria, Cameroon, Chad, Brazil, Australia, East Timor, New Zealand, West Coast & GOM USA, South Africa, Brunei, Myanmar and Malaysia etc. 

RESL have carried out peer reviews of decommissioning projects, decommissioning studies, engineered the removal of offshore structures, cost analysis for decommissioning accruals, managed decommissioning technology development of joint industry projects, acted as expert witnesses in decommissioning cost disputes and been involved in the post decommissioning analysis of removals in the Gulf of Mexico and the North Sea. Many of previous RESL studies have included socioeconomic impact analyses, cost/benefit assessment and decision analysis methodology.
