An Optimization Model for the Offshore Well Intervention Campaign: Literature Review

Abstract In the offshore oil industry, well-intervention barges provide crucial support for the production enhancement of offshore platforms. These specially designed ships contain tools and equipment to perform perforation activities that keep the wells active. However, with the relevance and practical operations, operators meet two principal challenges: 1) limited barge availability to serve a set of platforms and 2) each platform exhibits specific job requirements (different number of wells, duration, production gain, cost, time windows). This short literature review provides an overview of the Well Intervention Campaign Problem (WLICP) adopting the model of Vehicle Routing Problem considering Profits (VRPP). We propose four carefully designed questions to answer. It relates to 1) problem structure 2) modelling approach 3) solution technique and 4) optimization scenario. According to the result, WLICP exhibits a rigorous project management structure. Its structure contains the breakdown of n-sub-project representing VRP nodes. Combinatorial optimization helps barges find routes and schedules to maximize profit.
