Abstract

Estimating the Permeability of Carbonate Rocks from the Fractal Properties of Moldic Pores using the Kozeny-Carman Equation

Highlights

  • Scale invariance of intrinsic patterns is an important concept in geology that can be observed in numerous geological objects and phenomena

  • These geological objects and phenomena are described as containing statistically self-similar patterns often modeled with fractal geometry

  • The Kozeny-Carman equation describes the relationship between permeability and porosity assuming laminar flow in tubular cylinders

Summary

Introduction

Scale invariance of intrinsic patterns is an important concept in geology that can be observed in numerous geological objects and phenomena. Fractal geometry has been used extensively to characterize pore space and fracture distribution of both carbonate and clastic rocks as well as the transport properties of porous media and fluid flow in reservoirs (Pape et al 1987, Pape et al 1999). In this short paper we apply the modified Kozeny-Carman equation to estimate permeability from fractal properties of moldic pore spaces. We apply the equation to data from the Happy Spraberry Field, in Garza County, Texas
