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 ...
Novel fluorinated surfactants for enhanced oil recovery in carbonate reservoirs
(
Wiley-Liss Inc.
, 2016 , Article)
Novel surfactant‐polymer (SP) formulations containing fluorinated amphoteric surfactant (surfactant‐A) and fluorinated anionic surfactant (surfactant‐B) with partially hydrolyzed polyacrylamide (HPAM) were evaluated for ...
Flocculation and viscoelastic behavior of industrial papermaking suspensions
(
Springer New York LLC
, 2016 , Article)
The effects of the surface charge type and density C496, C492 and A130LMW polyacrylamides (PAMs) on the rheological behavior of real industrial papermaking suspensions were quantitatively related to the degree of flocculation ...
Development of a polyacrylamide-based mud formulation for loss circulation treatments
(
American Society of Mechanical Engineers (ASME)
, 2021 , Article)
Loss circulation materials in the last two decades have witnessed a lot of developments and implementations. New technologies and materials are introduced to treat various types of loss zones. However, the success rate is ...
A comprehensive rheological study for a flowing polymer-based drilling fluid used for wellbore strengthening
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
Loss circulation encountered in highly fractured formations, depleted reservoir, or HP/HT intervals is the root cause of many problems plaguing the oil and gas sector for many years. High pore pressure narrows the window ...
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 ...
Rheology of organoclay assisted extrusion of HDPE using Particle Image Velocimetry
(
Institution of Chemical Engineers
, 2015 , Article)
Wall slip is often seen as a source of flow enhancement and can play a significant role during certain melt instabilities in polymer processing. In the present investigation, the effect of organoclay on the wall slip of ...
Influence of choline chloride based natural deep eutectic solvent on the separation and rheological behavior of stable bentonite suspension
(
Elsevier B.V.
, 2021 , Article)
Colloids in wastewater are considered a serious problem due to their stability and separation difficulty. Coagulation/ flocculation processes are the most common for the separation of colloids because of their high-performance ...
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 ...
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
(
Elsevier B.V.
, 2016 , Article)
In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ...
