Knowledge of the maximum- and minimum-permeability directions in anisotropic reservoirs helps to optimize injector and producer locations and is important for reservoir management, especially under secondary or enhanced recovery of hydrocarbons. The complete paper describes a method using transient-test data rich with dynamic information aiming to provide fieldwide permeability distribution in well-spacing scale, which is relevant for estimating fluid movement and recovery.
Introduction
The knowledge of flow communication between wells is key information for reservoir management, especially in secondary or tertiary recovery. The surveillance methods to collect dynamic data to gain such knowledge include multiple-well pressure-transient tests and tracer tests. The measurements of tracer agents arriving at producing wells provide direct confirmation of flow communication.
