The molecular explanation for polyacrylamide viscosity reduction in high-salinity formation-water

AIP Advances, 2021
Many oilfields report that the viscosity of polymers in high-salinity reservoirs will decrease significantly. In this paper, molecular dynamics simulations were conducted to investigate the molecular configuration and network of hydrolyzed polyacrylamide

Enhancing the spontaneous imbibition rate of water in oil-wet dolomite rocks through boosting a wettability alteration process using carbonated smart brines

Petroleum Science, 2019
Most fractured carbonate oil reservoirs have oil-wet rocks. Therefore, the process of imbibing water from the fractures into the matrix is usually poor or basically does not exist due to negative capillary pressure.

An Experimental Investigation of Different Formation Waters and Injection Water Incompatibility to Obtain the Optimum Water Mixing Ratio in Injection Processes [PDF]

Journal of Petroleum Science and Technology, 2016
Scale formation and well plugging due to the incompatibility of injected waters is a critical field problem in oil recovery. A water injection process was successfully performed when the identification of the source of water, water quality considerations,

Realistic Simulations of the Galactic Polarized Foreground: Consequences for 21-cm Reionization Detection Experiments [PDF]

, 2010
Experiments designed to measure the redshifted 21~cm line from the Epoch of Reionization (EoR) are challenged by strong astrophysical foreground contamination, ionospheric distortions, complex instrumental response and other different types of noise (e.g.

Coupling Electrochemical CO2 Reduction With Ethanol Oxidation for Acetate Production in a Dual‐Electrolyzer System

Angewandte Chemie, EarlyView.
A tandem cell system coupling electrochemical CO2 reduction and electrochemical ethanol oxidation is demonstrated for overall acetate production, providing concepts for a CO2‐negative bioethanol to acetate pathway. ABSTRACT Bioethanol production from biomass is suggested as a strategy for greener fuel production.

Laboratory simulation and CO2 flooding efficiency of oil-water transition zones in a low permeability reservoir in the Jilin Oilfield

Petroleum Research, 2018
Geological reserves of oil-water transition zone (OWTZ) in low-permeability reservoirs have been considered as uneconomical resources because of high water cut and low abundance.

Interactions between Ca(OH)2, imidazolium ionic liquid, and titanium oxide nanoparticles using resinous and asphaltenic synthetic oils under high-salinity conditions

Journal of Petroleum Exploration and Production Technology, 2023
Using chemical methods in enhanced oil recovery (EOR) processes is limited since the mechanisms, interactions, and synergisms combined with heterogeneities and network complexities besides the incompatibilities of different chemicals are encountered in ...
