Investigation on degradation mechanism of polymer blockages in unconsolidated sandstone reservoirs

A new investigation on modeling of permeability reduction during CO2 flooding processes in sandstone oil reservoirs

Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...

Reservoir Characterization of Pennsylvanian Sandstone Reservoirs

On the Compaction and Viscous Behavior of Deep-Water Reservoirs

There have been many studies on reservoir compaction where different mechanisms being suggested as the reasons behind the integrity of unconsolidated reservoirs during production. Theory of poroelasticity is often used to evaluate the likelihood of compaction under these circumstances, but it is often failed to explain the creep behavior of unconsolidated formations. In this study, attempts are...
