Completion Selection Methodology for Optimum Reservoir Performance and Project Economics in Deepwater Applications

Abstract

Abstract This paper represents two main areas: (a) the interface between the wellbore and reservoir and the role of completion design in ensuring optimum reservoir exploitation, and (b) the risks inherent in various completion options as evaluated using current risk analysis techniques. Unique characteristics of various completion options will be presented and compared with regard to their impact on well productivity, cycle time and reliability. Case studies from the Gulf of Mexico and other deepwater environments are referenced to illustrate how the completion design impacts project economics, net present value and time to break-even. Risk analysis will be applied to well types to illustrate the potential savings in operating expense and overall completion cost.
