ABSTRACT
We explore the use of efficient streamline-based simulation approaches for modeling and
analysis partitioning interwell tracer tests in heterogeneous and fractured hydrocarbon reservoirs.
The streamline approach is generalized to model water injection in naturally fractured reservoirs
through the use of a dual media approach. The fractures and matrix are treated as separate
continua that are connected through a transfer function, as in conventional finite difference
simulators for modeling fractured systems. A detailed comparison with a commercial finite
difference simulator shows very good agreement. Furthermore, an examination of the scaling
behavior of the computation time indicates that the streamline approach is likely to result in
significant savings for large-scale field applications. We also propose a novel approach to history
matching finite-difference models that combines the advantage of the streamline models with the
versatility of finite-difference simulation. In our approach, we utilize the streamline-derived
sensitivities to facilitate history matching during finite-difference simulation. The use of finite-
difference model allows us to account for detailed process physics and compressibility effects.
The approach is very fast and avoids much of the subjective judgments and time-consuming
trial-and-errors associated with manual history matching. We demonstrate the power and utility
of our approach using a synthetic example and two field examples. Finally, we discuss several
alternative ways of using partitioning interwell tracer tests (PITTs) in oil fields for the
calculation of oil saturation, swept pore volume and sweep efficiency, and assess the accuracy of
such tests under a variety of reservoir conditions.3
