Validating the effectiveness of chemical flooding

摘要

Nano-sized particles help to increase incremental oil recovery in waterflood applications. Waterflood reservoirs that have high residual oil saturation are often targets for solvent, alkaline, surfactant and polymer chemical flooding during EOR processes designed to mobilize and recover that oil. The generally accepted sequence of events that takes place when considering the application of EOR chemicals begins with conducting laboratory (chemical formulation followed by coreflood testing) and computer simulation, followed by the chemical feed supply infrastructure design and installation and, finally, performing chemical injection into the reservoir.
