Introduction

Horizontal well with multi-stage hydraulic fracturing has become a standard completion method in the development of unconventional shale reservoirs. The multi-stage fracturing is typically carried out in a cased and cemented well by selectively placing multiple perforation clusters in a section of the horizontal wellbore (i.e., a stage), followed by pumping the frac-fluid into these perforation clusters. After completing the ...
