Fracture geometry is an essential aspect in hydraulic fracturing optimization. In this research a model (MYM) was developed to predict the geometry of the hydraulic fracture in shale formations and estimate shale gas production. After that a study was performed to identify the major parameters that affect fracture geometry. Previous models such as PKN and KGD which assume fixed height; pseudo-3D and planar-3D models which are complicated were studied. As a result of those problems of the mentioned models, MYM model was developed to exclude the assumption of fixed fracture height and to obtain more accurate results. It also introduces a new and simple equation to estimate the height of the fracture. MYM provides a modification for the half-length equation used by KGD which neglects fracture toughness and net pressure, this will influence fracture propagation noticeably. Fracture height and half-length equation were derived using dimensionless analysis. By using Sensitivity Analysis three rock properties were identified as the most important factors that affect fracture geometry, these parameters are Poisson's ratio, tensile strength and the fracture toughness. dc.publisher university of khartoum en_US dc.subject Model Of Hydraulic Fracturing In Shale Gas Formation en_US dc.title Model Of Hydraulic Fracturing In Shale Gas Formation en_US dc.type Thesis en_US
