This report provides Shell Todd Oil Service’s Completion and Well Intervention Engineering Department with feasible options for the completion design and execution strategy for proposed sidetrack wells for Maui B. The project provides results and recommendations that can be carried forward into the next project phase, including: -Completion design for the three proposed sidetrack well types for Maui B: crestal, down-dip and the extended reach Maui B North -Stress analysis for each proposed design -Execution program outline for the crestal wells -Cost analysis -Benchmarking against industry standard -Analysis of Completion and Well Intervention Engineering departmental communication and synergies The successes and failures of previous completion campaigns were analysed and heavily influenced the completion design for proposed sidetrack wells on Maui B. Shell standards, guidelines and open literature were called upon for the design. Findings in this report provide evidence of issues that should be addressed for the continuous improvement of both primary completion design and it’s synergy with the entire project group. Conclusions and recommendations have been provided for the consideration of Shell Todd Oil Service’s Completion and Well Intervention Team, Well Delivery Lead and Maui B Increased Recovery Project Team. This project has been prepared in partial fulfilment of the Master of Engineering Management (MEM) degree at the University of Canterbury for ENMG 606.
