ABSTRACT
In part II of this study, we present the application of the unsteady state solutions to fluid flow in naturally and or vertically fractured reservoirs whose internal boundaries are assumed to be ellipticaliy shaped. Type curves generated using solutions to unsteady-state elliptical flow equations are used to analyze several published field pressure data for parameters such as permeability, skin factor, wellbore storage and fracture length.
The field data analysis results show close agreement with results obtained using other reservoir flow geometries such as radial or linear.
