Investigation of Filter Cake Evolution in Carbonate Formation Using Polymer-Based Drilling Fluid
(
American Chemical Society
, 2021 , Article)
Drilling fluid and filtrates invasion often alter the near-wellbore flow properties during overbalanced drilling. The utilization of polymeric gels to prevent drilling fluid loss reduces the risk of formation damage caused ...
Theoretical studies of methane adsorption on Silica-Kaolinite interface for shale reservoir application
(
Elsevier B.V.
, 2021 , Article)
Shale gas is mostly made up of methane and is currently being exploited in fulfilling the world's energy demands. Density Functional Theory (DFT) and Molecular Dynamics (MD) techniques are employed for understanding methane ...
A CFD- RSM study of cuttings transport in non-Newtonian drilling fluids: Impact of operational parameters
(
Elsevier B.V.
, 2022 , Article)
Cuttings removal out of the wellbore represents a real barrier for successful drilling operations. The performance of hole cleaning is determined by several factors. The current article provides a theoretical study of the ...
CFD modeling of particle settling in drilling fluids: Impact of fluid rheology and particle characteristics
(
Elsevier B.V.
, 2021 , Article)
The settling of drilling cuttings is important for the drilling and clean-out operations. The current article provides a Computational Fluid Dynamics (CFD) modeling study of particle settling behavior during the drilling ...
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 ...
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 ...
