Pressure buildup from a vertically fractured low-permeability formation
Journal Article

· J. Pet. Technol.; (United States)
Buildup theory for a vertically fractured gas well was re-examined assuming planar flow against constant sandface pressure. The resultant pressure buildup is an arcsine function of a time group. If this relation is used to analyze buildup, it is possible to calculate the product of permeability and fracture half-length squared. This analysis gives better agreement with a set of field data and numerical simulation as compared with that from constant-rate theories using a Horner plot and a tandem-square-root time plot. 14 refs.
