The volumetric sweep efficiencies of CO 2 flooding for enhanced oil recovery (EOR) are
generally low due to problems of viscous fingering and gravity override. This paper attempts …

The CO2 huff-n-puff process is an effective method to enhance oil recovery (EOR) and
reduce CO2 emissions. However, its utilization is limited in a channeling reservoir due to …

The transition to sustainable, environmentally friendly, scalable, and affordable energy
sources has been the hardest challenge in global prosperity and economic growth since the …

The water-alternating-gas (WAG) operating scheme and reservoir permeability
heterogeneity are the main crucial parameters, which highlyaffect WAG displacement …

Abstract The CO 2 Water Alternating Gas (CO 2-WAG) injection method, allows the oil to first
expand and become better able to flow because of the CO 2, and then the water increases …

Matrix acidizing in sandstone reservoirs require a series of chemicals to dissolve the
plugging materials around the wellbore. The selection of suitable chemicals is important …

Low Salinity Water (LSW) incorporates in surfactant Enhanced Oil Recovery (EOR) as a pre-
flush is a common practice aiming to reduce the formation salinity, which affects surfactant …

In this study, CO2 Flooding simulation models were used to predict oil recovery. The models
were previously validated by laboratory experiments of continuous injection and water …

There are currently extensive studies that have evidenced the capability of nanoparticles in
stabilizing foam via irreversible adsorption at the gas/liquid interface. Nanoparticle …

Pressure Build Up analyses on a heavy oil well would give an inconclusive result on
pressure derivative curves. Some kind of thermal injection should be performed prior to …
