Enhancing the flocculation of stable bentonite suspension using hybrid system of polyelectrolytes and NADES
(
Elsevier B.V.
, 2022 , Article)
In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ...
Choline chloride based natural deep eutectic solvent for destabilization and separation of stable colloidal dispersions
(
Elsevier B.V.
, 2021 , Article)
In solid-liquid separation processes, coagulation/flocculation is one of the most popular techniques in treating wastewater, as it is efficient, simple, and economical. Consequently, the formation of a new environment ...
Impact of aluminium acetate particles size on the gelation kinetics of polyacrylamide-based gels: Rheological and molecular simulation study
(
John Wiley and Sons Inc
, 2021 , Article)
Inorganically crosslinked polymers have been intensively implemented for conformance control treatments in oil and gas wells at low temperatures (<90°C) because of their faster gelation time compared to organically crosslinked ...
Dissolution kinetics of different inorganic oilfield scales in green formulations
(
American Chemical Society
, 2020 , Article)
Scale mineral deposition is a critical problem that hinders the daily production of oil and gas fields. Chemical removal of these scales, based on the scale type, is common. In this paper, borax and diethylene tremaine ...
Ab-Initio Molecular Dynamics investigation of gas adsorption on α-quartz (001) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2021 , Article)
In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...
Development of greener d-metal inorganic crosslinkers for polymeric gels used in water control in oil and gas applications
(
MDPI AG
, 2020 , Article)
Crosslinkable polymers, such as polyacrylamide (PAM), are widely applied for water control in oil and gas reservoirs. Organic and inorganic crosslinkers are used to formulate a gel with PAM. Although chromium has a high ...
Effect of surface morphology on methane interaction with calcite: a DFT study
(
Royal Society of Chemistry
, 2020 , Article)
Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...
Enhancement of flocculation and dewaterability of a highly stable activated sludge using a hybrid system of organic coagulants and polyelectrolytes
(
Elsevier Ltd
, 2020 , Article)
This study investigates the influence of hybrid coagulation-flocculation system on the flocculation and dewaterability efficiency of a real highly stable activated sludge obtained from the membrane bioreactor tank of a ...
CO2 enhanced gas recovery and sequestration in depleted gas reservoirs: A review
(
Elsevier B.V.
, 2021 , Article Review)
Increasing CO2 emissions and global warming side effects have prompted the researchers to look for safe and reliable storage sites that have high capacity. Among the available CO2 capturing sinks, depleted gas reservoirs ...
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore strengthening: A review
(
Elsevier B.V.
, 2020 , Article Review)
Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods ...
