Monobore Completions for Slim-Hole Wells

Abstract

A growing number of operators are looking at monobore and slimhole completion techniques as possible solutions to economic and operational problems. Each technique can enhance the completion, and because the advantages of each concept affect a different phase of well technology, a broad spectrum of operational advantages could be generated is these techniques were merged into a single completion approach. Each philosophy, however, requires specialized equipment to provide its benefits, and attempts to unite the two strategies have created unique challenges for equipment designers. In many cases, these challenges are not really fully understood. This paper overviews several new equipment designs that are ideally suited for monobore completions in slim-hole wells. Also discussed are new servicing methods and how using these options and the newly designed equipment can overcome the difficulties challenging the design of completion equipment for the combined technologies.
