Montney Unconventional Gas - Next Generation, An Integrated Approach to Optimizing Wellbore Completions Technology

摘要

In this paper we will present the evolution of well construction in the Montney play, technical and economical challenges, and the new synergy developed between drilling and completions. The financial driver that all operators are facing today is to lower well construction costs. The drilling and completions processes should not be looked at as separate entities but rather as an integrated team. This will allow for the achievement of an optimal solution for overall well construction, a solution that can not be achieved by either discipline in isolation. This paper demonstrates the evolution of a unique completion system that lowers costs in a technically challenging area. Case histories of two completion methods, swellable packers and cemented sliding sleeve technologies are discussed in detail. The cemented sliding sleeve systems were deployed at a field scale for the first time in North America in the Pouce Coupe area of Alberta, Canada in December 2008.
