Chemical combination flooding techniques, particularly alkali/surfactant/polymer (ASP)
flooding, have proved to be effective in enhanced oil recovery (EOR). The development of …

Sandy conglomerate reservoirs have become an important replacement area for
unconventional energy to increase reserves and production. The polymer/surfactant …

Abstract Alkaline-Surfactant-Polymer (ASP) flooding is an efficient method but was poorly
applied in the industry as it is costly. The best mixture and injection sequence is also …

Crude oil production from Niger Delta reservoirs has proceeded into secondary phase, and
with time the need for enhanced recovery will arise. Therefore, this work investigates …

Polymer play a key role in several EOR processes such as polymer flooding, surfactant-
polymer flooding and alkaline-surfactant-polymer flooding due to their critical importance of …

Capillary forces, inappropriate mobility ratio & reservoir heterogeneity account for trapped oil
in reservoirs after the secondary process. To optimise the recovery of this left behind Oil …
