Extended-Reach Wells Help Optimize Production in Marginal Offshore Prospects

Abstract

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 202896, “Optimizing Production From Marginal and Challenging Prospects To Unlock Field Potential: Success Cases in the Jasmine Field, Gulf of Thailand,” by Mukminin Yusuf, SPE, Pattarapong Prasongtham, SPE, and Theeranun Limniyakul, SPE, Mubadala Petroleum, et al. The paper has not been peer reviewed. The development of marginal volumes in the Jasmine field is part of the operator’s strategy to extend the field’s life, involving the exploitation of increasingly challenging prospects. The complete paper highlights two case studies to illustrate how the operator has developed marginal prospects to unlock the Jasmine field’s remaining potential successfully. The use of autonomous inflow control devices (AICD) has played a significant role in optimizing production in reservoirs with small oil rims and thick gas caps. Jasmine Field The designation “Jasmine field” is commonly used to refer to both the Jasmine field and the neighboring Ban Yen field, which are essentially one integrated field from an operational perspective. The fields are in the Gulf of Thailand, approximately 300 km southeast of Bangkok in depths of 190 to 200 ft (Fig. 1).
