Use of a Good-Enough Strategy to Reduce Costs of Development of Deep Offshore Brown-Field Marginal Infill Reservoir

摘要

Girassol Miocene M14 project, a Brown Field subsea tie-back to Girassol FPSO on Block17 in Angola,rnwas suspended after pre-project/FEED studies to give priority to more profitable developments. In arnpermanent attempt to develop the upside reserves of TOTAL Angola portfolio at the best costs, anrnalternative development scenario was envisaged early 2015 considering the use of stock drilling tubular,rncompletion equipment as well as SPS equipment, the reuse of existing XTs recovered from depletedrnGirassol wells, the selection of minimum functionalities system.rnThis paper presents how a u0002good-enoughu0002 strategy has been used to generate real cost savings andrnschedule optimization for the project. All together, this is a first-of-a-kind for deepwater fields in TOTAL.
