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 ...

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 ...

Horizontal wells provide high drainage area within the reservoirs. Advancements in horizontal drilling technologies are utilized to develop unconventional resources such as shale gas and coal bed methane. However, wellbore ...

Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, ...

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 ...

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 ...

Stable emulsions are frequently encountered in oil production and cause a series of environmental and operational issues. Chemical demulsification is widely used for the separation of oil from water or removal of water ...

In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ...

A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales ...

Iron sulfide scale is one of the main types of inorganic scales that block oil and gas wells. Iron sulfide has polymorph crystallinity structures, which complicate its dissolving and inhibition. Hydrochloric acid (HCl) is ...
