... and a sharp permeability jump in between, representing a lamination or cross-lamination. Unlike previous studies, gas and surfactant solution were co-injected at field-like velocities into a medium at steady-state to gas-brine co-injection. Pressure gradient is measured across several sections of the core. X...

... surfactant solutions for "Enhanced Oil Recovery (EOR)" applications. Results show that microfluidic technology give detailed pore-level insights into multi-phase displacement of oil by surfactant solutions including percolation of emulsions. Further, if applied they can accelerate the surfactant screening...

... can be monitored by using of tracer technology. Variations in the flow rates of surfactant solution and CO 2 can be clearly detected, and the accessible pore volume can also be determined. AOS products contain different chemical structures. In the study, the main AOS components have been chemically...
