CO2 injection has recently been shown to provide significant enhanced oil recovery from naturally fractured reservoirs1. Li et al. (2000) performed CO2 injection at 1750 psig on artificially-fractured cores after water flooding in a dead-oil system. Gravity drainage was suggested to be the dominant recovery mechanism in these tests, with significant tertiary oil recovery after water flooding. The authors observed that the recovery of initial oil at the start of the CO2 injection declined as the rock permeability decreased and the initial water saturation increased | Sayyed Ahmad Alavian Modeling CO2 Injection in Fractured Reservoirs Using Single Matrix Block Systems Sayyed Ahmad Alavian Modeling CO2 Injection in Fractured Reservoirs Using Single Matrix Block Systems Trondheim October 2011 Norwegian University of Science and Technology Faculty of Engineering Science and Technology Department of Petroleum Engineering and Applied Geophysics 0 NTNU - Trondheim Norwegian University of Science and Technology To my .
