| Abstract | In present, oil price crisis is affecting oil and gas business worldwide, particularly in explorat ion and production stage s . Reuse platform is one of structural preferred strategies , but lack of information regarding reuse process is the significant problem. This study aims to establish a framework for considering reused jackets from die up field to green field development , and performs a case study which follows the delivered procedure in order to determine benefits generated. A simple four leg wellhead jacket with single diagonal brace installed in 90 - meter of water depth for 20 years and moved to 70 - meter for 11 years in the Gulf of Thailand was modeled to an alyze platform’s fati gue condition . The analysis was performed using fa tigue analyzed function in SACS software program . T he results s howed that new environment required CDR of 0.12 and CDR available from prior field was 0.64 thus this structure could be an alternative with the safety factor of 5.33. Additionally, economic a nalysis was investigated based on contractor’s document and Thai III fiscal regime . The outcomes indicated that cost a nd schedule of reuse project is saver by 8.3 million USD and 9 months respectively , and all economic indicators (NPV, IRR and PI) of reus e project are higher for every given oil prices. Finally, the extant oil price forecasting models were briefly discussed, and the demonstration of IRR comparison for three example models (EIA, IMF and World Bank model) was made to study effects of oil pric e to IRR received. The results presented that a reused project generate d higher IRR by 7.8%, 8.4% and 9.0 % respectively. |
