Laboratory Investigation of Process Zone Stress
This dissertation has as its main objective the study of the phenomena known as Process Zone Stress (PZS), which in the past, has been of high concern in the petroleum engineering industry during hydraulic fracture operations in conventional permeability reservoirs and has had a rebirth for tight shale reservoirs. In order to study PZS, a comprehensive review of fracture tip mechanisms, specifically of process zone stress was performed. The literature review provided a path towards the required experimentation to characterize this phenomena. Due to the subsurface nature of the oil and gas industry, ...
