Hydraulic Fracturing Length Optimization and its Impact on the Reservoir Performance [PDF]
Journal of Petroleum Science and Technology, 2018 Hydraulic fracturing is one of the most common methods of well stimulation for reservoirs with low permeability. Hydraulic fracturing increases the flow capacity, alters flow geometry, bypasses damage and improves recovery factor. The pressure of most of

Simulation of Hydraulically Fractured Wells
IOR 1997 - 9th European Symposium on Improved Oil Recovery, 1997 Fractured wells are frequently encountered in petroleum engineering. They can be hydraulically fractured wells to improve oil production or wells intersecting natural fractures. Due to the presence of the fractures, the flow behaviour and the pressure distribution in the vicinity of the fractured well are complex and the numerical modelling for this ...
