Evaluation of Alternative Solutions to Recover Deferred Oil Production Due to Facility Constraint: Case Study of Bravo Gathering Station in an Oil Company, PT XYZ

Abstract

Bravo is one of PT. XYZ's biggest oil fields and its fluid production is treated at Bravo Gathering Station. Lately, Bravo GS has been facing a serious production problem. Several oil producers are shut-in as the field production exceeds the processing capacity. This has resulted a significant amount of deferred-oil-production (DOP) and revenue loss. This research aims to identify the root cause and figure out the solution to eliminate constraints. Brainstorming and Focus Group Discussions with experts is extensively used in this research during problem analysis and alternative creation using Value Focused Thinking (VFT) approach. Multiple alternative solutions are developed, using safety, economic performance, cost efficiency, and execution cycle time as the decision criteria. Analytical Hierarchy Process is used in this research for decision making process, and Experts are requested to provide rating on pairwise comparisons of each criterion and alternative based on their technical knowledge and experience. The 3rd alternative solution which reduce the incoming water production through the water shut-off (WSO) job appears to be the best alternative solution according to the consolidated AHP result. The result indicates that this alternative has a very strong upside on safety, cost efficiency, and execution cycle-time criteria among other alternatives. Keywords: Deferred Oil Production (DOP), Constrained Production, Value-Focused Thinking (VFT), Analytical Hierarchy Process (AHP
