Application of response surface methodology and box-behnken design for the optimization of the stability of fibrous dispersion used in drilling and completion operations
(
American Chemical Society
, 2021 , Article)
Fibers are extensively used as a fluid additive in the oil and gas industry to improve hole-cleaning performance, control fluid filtration loss, and enhance hydraulic fracturing effectiveness. Generally, a small amount of ...
Influence of polyelectrolyte structure and type on the degree of flocculation and rheological behavior of industrial MBR sludge
(
Elsevier B.V.
, 2020 , Article)
The influence of polyelectrolyte's type and structure on the rheological characteristics of industrial highly stable membrane bioreactor (MBR) sludge have been investigated and were related to its degree of flocculation ...
Development of pH-Controlled Aluminum-Based Polymeric Gel for Conformance Control in Sour Gas Reservoirs
(
American Chemical Society
, 2020 , Article)
Excessive water production from natural gas reservoirs is a main challenge facing the industry nowadays. Polymeric gelants have been widely applied to seal the water production zones, leading to a more feasible production ...
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 ...
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 ...
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
Enhanced Adsorption of Selenium Ions from Aqueous Solution Using Iron Oxide Impregnated Carbon Nanotubes
(
Hindawi Limited
, 2017 , Article)
The aim of this research was to investigate the potential of raw and iron oxide impregnated carbon nanotubes (CNTs) as adsorbents for the removal of selenium (Se) ions from wastewater. The original and modified CNTs with ...
Osmotic pressure estimation using the Pitzer equation for forward osmosis modelling
(
Taylor and Francis Ltd.
, 2020 , Article)
Forward osmosis (FO) has received widespread recognition in the past decade due to its potential low energy production of water. This study presents a new model analysis for predicting the water flux in FO systems when ...
