With the statistical distributions of fracture length and height from different completion...

... important definition of effective fracture length is that it affects the transient production of the stimulated well. Early in the producing life of a fractured well the transient is dominated by linear flow into the faces of the effective fracture. With more producing time, the transient moves further from...

... (1953) and then modified by Terrill (1965) . Schechter (1992) adapted the solution for the acid flow in the fracture. The solution for the average acid concentration as a function of position along the fracture length is given as the following expression (13) C ¯ C 0...

After establishing the confidence on the capacity of those models, we then further studied the impact of different completion designs on fracture dimensions and well performance. We examined the distributions of fracture length along the wellbore resulted from...

... was varied by a factor of two to evaluate the effect of fluid volume on fracture length. Microseismic data were gathered on 81 PNP stages and 95 CEP stages. The microseismic data were used to calibrate hydraulic fracture models. Fracture geometries for the five-well pad plus a direct offset well (a six well...
