Predicting Productivity of Multiple-Fractured Horizontal Gas Wells
In low-permeability gas reservoirs, horizontal wells have been used to increase the reservoir contact area, and hydraulic fracturing has been further extending the contact between wellbores and reservoirs. This paper presents an approach to evaluate horizontal well performance for fractured or unfractured gas wells, and a sensitivity study of gas well performance in low permeability formation. ...

متن کاملPerformance of Longitudinally Fractured Horizontal Wells in High-Permeability Anisotropic Formations
This work studies the combined behavior of (1) horizontal wells, and (2) high-permeability fracturing. Fractured vertical WCIIS in high-permeability formations always yield finite conductivity fractures which in turn can reduce the benefits of the stimulation. It has been proposed recently that a fracture along a horizontal WC1lposes far smaller pressure drops than those of the fracture interse...
متن کاملPerformance Model for Vertical Wells with Multi-stage Horizontal Hydraulic Fractures in Water Flooded Multilayer Reservoirs
For the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...
متن کاملModeling flow into horizontal wells in a Dupuit-Forchheimer model.
Horizontal wells or radial collector wells are used in shallow aquifers to enhance water withdrawal rates. Groundwater flow patterns near these wells are three-dimensional (3D), but difficult to represent in a 3D numerical model because of the high degree of grid refinement needed. However, for the purpose of designing water withdrawal systems, it is sufficient to obtain the correct production ...
