Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
(
Elsevier Ltd
, 2021 , Article)
Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ...
Electrochemical removal of pyrite scale using green formulations
(
Nature Research
, 2021 , Article)
Pyrite scale formation is a critical problem in the hydrocarbon production industry; it affects the flow of hydrocarbon within the reservoir and the surface facilities. Treatments with inorganic acids, such as HCl, results ...
BET, FTIR, and RAMAN characterizations of activated carbon from waste oil fly ash
(
TUBITAK
, 2020 , Article)
Activated carbon (AC), a porous material with high pore volume, attracts increasing attention owing to
its potential applications in several fields. The development of a porous structure in AC marginally relies on both
the ...
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 ...
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 ...
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 ...
