Comparisons of counter-current imbibition transfer functions in dual porosity models of naturally fractured reservoirs
- Dept. of Petroleum Engineering, The Univ. of Texas at Austin, Austin, TX (US)
Models for fluid flow in naturally fractured reservoirs have been developed by the oil industry for at least the last three decades. Although a variety of techniques have been attempted to simulate these complex systems, the most efficient approach appears to be the dual porosity model. In dual porosity models, transfer functions are critical components that describe fluid flows between matrix blocks and surrounding fractures. Model results are very sensitive to the matrix/fracture transfer function, and it is usually these transfer functions that distinguish different models. In this paper, the authors classify transfer functions reported in the literature into five categories: basic transfer functions (BTF), transfer functions with explicit gravitational effects, transfer flow calculations based on discretization of matrix blocks, such as multiple interacting continua (MINC), transfer functions with pseudo-curves, and other models. A comprehensive review of these transfer functions is presented, followed by a discussion of their differences and similarities.
