Calcite Scale Inhibition Using Environmental-Friendly Amino Acid Inhibitors: DFT Investigation
(
American Chemical Society
, 2021 , Article)
Scale prevention is a long-term challenge. It is essential for ensuring the optimum utilization of oil and gas wells and minimizing economic losses due to disruptions in the hydrocarbon flow. Among the commonly precipitated ...
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 ...
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales
(
American Chemical Society
, 2020 , Article)
In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown ...
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 ...
Ab initio molecular dynamics investigation of CH4/CO2 adsorption on calcite: Improving the enhanced gas recovery process
(
American Chemical Society
, 2020 , Article)
Ab initio molecular dynamics simulations of CH4 and CO2 on the calcite (104) surface have been carried out for the molecular level analysis of CO2-enhanced gas recovery process (EGR). This process takes advantage of the ...
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 ...
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 ...
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 ...
