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 ...
Molecular Design of Novel Chemicals for Iron Sulfide Scale Removal
(
Hindawi Limited
, 2021 , Article)
Scale deposition is a pertinent challenge in the oil and gas industry. Scales formed from iron sulfide are one of the troublous scales, particularly pyrite. Moreover, the use of biodegradable environmentally friendly ...
Large CO2 uptake on a monolayer of CaO
(
Royal Society of Chemistry
, 2017 , Article)
Density functional theory calculations are used to study gas adsorption properties of a recently synthesized CaO monolayer, which is found to be thermodynamically stable in its buckled form. Due to its topology and strong ...
Pyrite-scale removal using glutamic diacetic acid: A theoretical and experimental investigation
(
Society of Petroleum Engineers (SPE)
, 2021 , Article)
Iron sulfide scale causes major losses in both upstream and downstream sectors of the hydrocarbon industry. Pyrite is one of the most-difficult forms of iron sulfide scale from a removal point of view. Inorganic acids such ...
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 ...
Reinforcement of polyacrylamide-co-tert-butyl acrylate base gel using nanosilica for conformance control at low and high reservoir temperatures
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
Challenges of water shut-off, which is categorized under conformance control, are nowadays common in the oil and gas industry. The excessive water quantities produced from oil reservoirs can make the production process ...
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 ...
Hydrothermally grown ZnO electrodes for improved organic photovoltaic devices
(
Elsevier B.V.
, 2018 , Article)
Here we report a simple, solution based processing route for the formation of large surface area electrodes resulting in improved organic photovoltaic devices when compared with conventional planar electrodes. The ...
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 ...
