Modeling the Impact of Subseismic Scale Fractures on Macroscale Block Properties and Flow Performance
Abstract/Contents
- Abstract
- In this thesis, a method to simulate subseismic scale fractures and evaluate their impact on flow performance is proposed. A representative panel is considered for each geologically distinct reservoir unit. Small scale fractures are then simulated within the panel and their impact on flow simulation block effective properties is assessed. The resulting within-panel statistics are then extended to simulate these block properties over the entire unit, and simulation of flow performance is performed over that unit. As expected, the simulated fracture porosity has little impact on the total effective porosity, but the simulated fracture permeability has a significant impact on the total effective permeability. Hudson's relation is used to study the impact of fractures on seismic velocity. It is found that the velocity anisotropy and S-wave splitting appear in the fractured model. These features could be used to detect the existence of fractures. The impact of fractures on fluid flow is studied for both primary depletion and water injection.
