Enhanced Oil Recovery: Chemical Flooding

open access: yesGeophysics and Ocean Waves Studies, 2021
The enhanced oil recovery phase of oil reservoirs production usually comes after the water/gas injection (secondary recovery) phase. The main objective of EOR application is to mobilize the remaining oil through enhancing the oil displacement and ...

Laboratory evaluation and numerical simulation of the alkali-surfactant-polymer synergistic mechanism in chemical flooding. [PDF]

open access: yesRSC Adv, 2018
Alkali–surfactant–polymer (ASP) flooding, which can reduce interfacial tension (IFT) and the mobility ratio between oil and water phases, has been proven to be effective for enhancing oil recovery in laboratory experiments and field pilots.

Efficient Scheme for Chemical Flooding Simulation [PDF]

open access: yesOil & Gas Science and Technology, 2014
In this paper, we investigate an efficient implicit scheme for the numerical simulation of chemical enhanced oil recovery technique for oil fields. For the sake of brevity, we only focus on flows with polymer to describe the physical and numerical models.

A New Generation Chemical Flooding Simulator [PDF]

open access: yesProceedings of SPE/DOE Symposium on Improved Oil Recovery, 2004
SummaryCompositional reservoir simulators that are based on equation-of-state (EOS) formulations typically do not handle the modeling of aqueous phase behavior, and those that are designed for modeling chemical processes typically assume simplified hydrocarbon phase behavior.
