Abstract

The main objective of this study is to determine the location of the flood front, reservoir rock and fluid properties and fracture parameters via history matching of the test data. It is assumed that flow inside the matrix is two-dimensional, and one-dimensional inside the fracture. Two different fluid flow equations, one for the matrix and the other for the fracture, are used to describe the single-phase flow conditions. Four different fluid loss models in three different flow geometries (elliptical, linear and radial) are considered. These two non-linear equations are linearized numerically, and the resulting two systems of linear equations are solved simultaneously using the alternating direction implicit procedure. Extensive testing and validation of this generalized formulation was conducted by using it to study nine special cases previously reported in the literature. The results indicate that as the power-law index increases, the dimensionless bottom-hole pressure increases for a given injection rate.
