Abstract:
Understanding production performances of shale gas wells is important for reserves assessment and production optimization. Type curve analysis is a practical method used in the industry; but there are a number of limitations in applying traditional type curves in shale gas reservoirs because of the unique storage and flow mechanisms in shale gas reservoir. Thus specialized type curves are necessary. In this research, first I understood the storage and flow mechanisms in conventional and shale gas reservoirs; then I critically reviewed development and applications of type curves in conventional and shale gas reservoirs. The third step I developed a specialized multiphase, multi-mechanics type curves capable of analyzing production performances of shale gas wells based on our numerical simulation results, and finally applied and validated my type curves in a Marcellus well. This newly developed type curves could help engineers analyze shale gas well performances and identify potential production issues in a systematic and pragmatic manner.
