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, ...
Gelation kinetics of PAM/PEI based drilling mud for lost circulation applications
(
Elsevier B.V.
, 2021 , Article)
The problem of lost circulation is a direct consequence of the presence of fractures or high permeability. Lost circulation material (LCM) is used to treat the loss that occurs or proactively strengthen the wellbore of the ...
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 ...
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 ...
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 ...
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 ...
