Rheology of a viscoelastic zwitterionic surfactant used in acid stimulation: Effects of surfactant and electrolyte concentration
(
Elsevier
, 2014 , Article)
Acid diversion systems play an important role in increasing the efficiency of the acid stimulation process. Viscoelastic surfactant (VES) based diverting systems have many advantages that make them preferred for well acid ...
Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Influence of polyelectrolyte architecture on the electrokinetics and dewaterability of industrial membrane bioreactor activated sludge
(
Academic Press
, 2019 , Article)
Improvement of sludge dewaterability is greatly hindered by the presence of large amounts of interstitial water molecules trapped in the sludge as a result of strong hydrophilic characteristics. This study has investigated ...
Rheology of Triamine Functionalized Silica Reinforced Polymeric Gels Developed for Conformance Control Applications
(
American Chemical Society
, 2020 , Article)
Recently, cross-linked polymers such as polyacrylamide (PAM)/polyethylenimine (PEI) have been used in conformance control applications to replace conventional lost circulation materials (LCMs). The objective of this work ...
Investigation of thin-film composite hollow fiber forward osmosis membrane for osmotic concentration: A pilot-scale study
(
Springer
, 2022 , Article)
The current study applied the forward osmosis (FO) based osmotic concentration (OC) process at the pilot-scale for concentrating synthetic feed solution (FS). The process water (PW) salinity represents effluents from the ...
Settling behavior of fine cuttings in fiber-containing polyanionic fluids for drilling and hole cleaning application
(
Elsevier B.V.
, 2021 , Article)
For efficient drilling operations, cuttings transport within the oil and gas wellbore is fundamental. Inadequate hole cleaning results in many problems including reduced rate of penetration, increased torque, bit wearing, ...
Assessing the relation between mud components and rheology for loss circulation prevention using polymeric gels: A machine learning approach
(
MDPI AG
, 2021 , Article)
The traditional way to mitigate loss circulation in drilling operations is to use preventative and curative materials. However, it is difficult to quantify the amount of materials from every possible combination to produce ...
Investigation of the effect of polyelectrolyte structure and type on the electrokinetics and flocculation behavior of bentonite dispersions
(
Elsevier B.V.
, 2017 , Article)
The influence of surface charge type and density, and molecular weight of cationic, anionic and amphoteric polyacrylamide (PAM) on the electrokinetics, adsorption and flocculation behavior of highly stable bentonite ...
Gelation kinetics of functionalized silica crosslinked polymeric gels used in conformance control applications
(
John Wiley and Sons Inc
, 2021 , Article)
The potential crosslinking of three types of nitrogen-containing functionalized silica (TAAcONa, guanidine, and triamine) with polyacrylamide (PAM) has been investigated. Only triamine silica was able to crosslink with ...
Destabilization of stable bentonite colloidal suspension using choline chloride based deep eutectic solvent: Optimization study
(
Elsevier Ltd
, 2021 , Article)
Choline chloride (ChCl) based natural deep eutectic solvents (NADES) were synthesized and tested as coagulant for stable bentonite colloidal suspensions. In this work, three ChCl based natural deep eutectic solvent NADES ...
