Uniformly-Fractured Aquifers

Introduction

Introduction Double-Porosity Theory (Barenblaa et al.

1960) 2 Media

◦ The fractures◦ The matrix blocks

Matrix=primary porosity in the and low permeability Fractures= low storage capacity and high permeability

Introduction No variation in head within the matrix

blocks is assumed This so called interporosity flow is in

pseudo-steady state The flow through the fractures to the well is

radial and in an unsteady states.
