The interaction of shale/fracture/fluid interactions and the resulting geomechanical behavior of shale oil unconventional reservoirs is becoming of greater interest as the impact of pressure dependent fracture conductivity is better understood. As more operators develop these resources the diversity in the constituents of the shale and the presence of water-sensitive clays require different approach to yield better EUR results. These efficiency gains are more than just placing proppant and identifying the best acreage with good natural fracture systems. By controlling clay/fluid interactions it is possible to improve pressure dependent fracture conductivity response and improve EUR. The focus of this paper is to investigate stress dependent fracture conductivity, shale/fracture/fluid interactions and the potential of more intelligent completions to improve EUR.
