Pyrite Scale Removal Using Green Formulations for Oil and Gas Applications: Reaction Kinetics
(
American Chemical Society
, 2019 , Article)
Pyrite is one of the toughest iron sulfide scales to remove, which causes major problems in oil and gas production by damaging production equipment. The use of inorganic acid in iron sulfide scale removal particularly ...
Density-Functional Theory Investigation of Barite Scale Inhibition Using Phosphonate and Carboxyl-Based Inhibitors
(
American Chemical Society
, 2020 , Article)
Scale deposition is a critical issue in oil and gas exploration and production processes, causing significant blocking in tubing and consequently flow assurance and economic losses. Most studies addressing the scale formation ...
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 ...
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 ...
Application of DFT in iron sulfide scale removal from oil and gas wells
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ...
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 ...
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 ...
Dissolution kinetics of different inorganic oilfield scales in green formulations
(
American Chemical Society
, 2020 , Article)
Scale mineral deposition is a critical problem that hinders the daily production of oil and gas fields. Chemical removal of these scales, based on the scale type, is common. In this paper, borax and diethylene tremaine ...
Effect of surface morphology on methane interaction with calcite: a DFT study
(
Royal Society of Chemistry
, 2020 , Article)
Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...
