A transient flow solution to describe fluid flow to horizontal fractures applied to frac‐packed wells

This paper presents an analytical model to describe the transient fluid flow a horizontal fracture in frac-packed vertical wells. A physical is first established where located middle of cylindrical reservoir. The pressure distribution then derived concerning time and distance wellbore. assumes homogeneous isotropic reservoir Darcy's law applies single-phase flow, radial with radius much greater than pay zone thickness, constant width. For ease application, Type Curve Matching approach introduced which features matching defined dimensionless between field data data, some exemplar curves are illustrated this paper. principle applying curve here tune parameters match measured pressure/rate data. Once matched, parameters, that is, permeability, etc, naturally obtained. validity informed two ways. results show will degenerate classic equation for practical values certain upon reasonable simplification. Model further verified by type technique using can be used as quick method analyze test reveal fundamental properties at shallow depths formation stress least situ stress.
