Estimation of Matrix Block Size Distribution in Naturally Fractured Reservoirs
Abstract/Contents
- Abstract
- Interporosity flow in a naturally fractured reservoir is modelled by a new formulation incorporating variability in matrix block size. Matrix block size is inversely related to fracture intensity. The size of matrix elements contributing to interporosity flow is expressed as a distribution in the source term of the diffusivity equation. The pressure transient response for uniform and bimodal distributions of block size is investigated. Both pseudo-steady state and transient models of flow are analysed. It is shown that features observed on the pressure derivative curve can yield the parameters of the distribution. Thus, observed pressure response from fractured reservoirs can be analysed to obtain the matrix block size distribution in the volume of the reservoir investigated by the test.The solution to the uniform distribution can be extended to more general distributions. Other sources of information, like logs and geological observations, can give an estimation of the shape of the distribution, and this model can be used to compute the reservoir parameters.
