Evolution of Seismic Velocities in Heavy Oil Sand Reservoirs during Thermal Recovery Process

Evolution of seismic velocities in heavy oil sand reservoirs during thermal recovery process Évolution des vitesses sismiques dans les réservoirs de sables bitumineux au cours des procédés de récupération thermique

In thermally enhanced recovery processes like cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD), continuous steam injection entails changes in pore fluid, pore pressure and temperature in the rock reservoir, that are most often unconsolidated or weakly consolidated sandstones. This in turn increases or decreases the effective stresses and changes the elastic properties of...

Seismic Attributes Method for Prediction of Unconsolidated Sand Reservoirs of Heavy Oil

Heavy crude oil is known as oil that is highly viscous and of a higher density than that of conventional oil. Sand reservoirs containing heavy oil generally consist of unconsolidated sediments deposited at a shallow burial depth, with high porosity and permeability. In seismic exploration, acoustic impedance inversion is a commonly used tool in reservoir prediction. However, due to the unconsol...

Enhanced Oil Recovery in Fractured Reservoirs

Simulation of Oil Reservoirs Driving Indices and Recovery Mechanisms

Different recovery mechanisms are activated during the production from reservoirs. Wells sometimes are kept with the injection. Therefore the evaluation of injection indices depended on material injection, seems to be necessary. This study is going to determine the drive indices for a reservoir by making a model using Eclipse. The model consists a gas cap and aquifer, in which there is an injec...
