Paper Number: URTEC-3864802-MS
... Abstract In past studies, changes in fluid pressure in natural fractures (planes of weakness) have been ignored for the interaction of hydraulic and natural fractures. To overcome these limitations, in this paper we develop a method to simulate the growth of hydraulic fractures...

...-phase techniques. Introduction Devon Energy have performed 46 so-called ‘refracs’ in the Eagle Ford. A ‘refrac’, or refracturing, refers to the process of performing hydraulic fracturing again on a well that has already undergone the process in the past. It involves pumping a fluid at high pressure...

Paper Number: URTEC-3864846-MS
... Abstract Proppant transport is critical in hydraulic fracturing treatments because it directly affects the effective/propped fracture geometries. While much research has been devoted to proppant transport simulation, the popularity of Eulerian-Lagrangian (E-L) models in proppant transport only...

... Abstract Rock properties are assumed constant or to vary only slightly along a horizontal well placed within a correlative target. However, in the presence of folds, faults and/or fractures, the geomechanical properties can change along the well leading to skewed hydraulic fracture development...

Paper Number: URTEC-3869162-MS
... Abstract Numerical simulation of hydraulic fracture propagation is increasingly used to evaluate the effect of various mechanistic aspects (e.g., inclusion of poroelastic effects, proppant transport, etc.), and of several variables, on the result of a stimulation operation at varying scales...
