BROADBAND MULTI-SURVEY FWI IMPACTS ACCELERATED CARBONATE DRILLING CAMPAIGN

X field is a shallow water carbonate gas field in offshore Sarawak which came on stream in 2015. It is a large sweet gas resource, however, with low recovery factor due to the complexity of the field including highly karstified reservoir with short gas column, ‘pancake’ structure and a strong aquifer drive. The field complexity was further evidenced by early water breakthrough, several months earlier than the Field Development Plan forecast. Following the water breakthrough, decision was made in 2017 to accelerate Phase 2 infill development to safeguard the field production. Broadband Multi-survey FWI was one of the technology identified to help in placing the wells. This paper will show the improved image of the new data impacts the drilling campaign.
