Planning, Organization And Success Of A Wide, Detailed Geophysical Survey Offshore Makassar Strait

Abstract

The Oil & Gas industry has seen recently a strong push towards high end goals required by the tight bond between economics, the time for the development of an investment, planning and finally construction and service of plants. This is the specific case of the Jangkrik field development. As part of the POD (Plan of Development) approval by the Government of Indonesia, eni Indonesia committed to a "fast track" strategy in which the field would come into production in 2016 and consequently directed all efforts towards early development of the engineering design for the production facilities. Thanks to the execution of the geophysical site investigations during the early project design stages, several elements were discovered, which quality allowed a much clearer picture of several morphologic elements affecting the field design. Among the most important decisions that were taken during this design phase, we can consider the one to relocate the FPU in a shallower water depth (100mt WD on the continental shelf) with respect to the preliminary design (about 320mt WD along the escarpment). Such decision, if not taken on time, would have created major reworks during the execution phase, together with a potential big delay in the project and potentially jeopardizing the possibility of the Jangkrik North East integration. Another important decision was the one relevant to the use of rigid versus flexible flow lines. This is also critical for the procurement activities to be progressed on time and also for the flow assurance studies. This type of decisions, taken during this phase of the project, in the long term will lead to better design, minimize re-works, reduce costs and time and ensure project integrity.
