There is still considerable controversy surrounding the mechanisms, thermodynamics, and
kinetics of heavy oil aquathermolysis and pyrolysis processes. The present paper aims to …

Our knowledge of electromagnetic heating's effect on heavy oil upgrading is largely based
on very limited data. The aim of the present research was thus to study in detail the effect of …

During thermal evolution, the kerogen in shale formation undergoes significant chemical,
structural and compositional changes, continuously influencing the shale storage capacity …

The development of heavy oil has become increasingly important due to the demand of
human society for energy. The in-situ upgrading is a technology using transition metal …

Thermal recovery methods using steam injection are widely employed for heavy oil and
bitumen production, but upgrading challenges persist with these highly viscous feeds …

Heavy oil reserves are recognized as being a significant yet challenging energy resource
due to high viscosities. It is common knowledge that thermal recovery methods like in situ …

The feasibility of the autothermic pyrolysis in situ conversion (ATS) process for low-grade oil
shale (OS) has not been determined. In this research, the pyrolysis and combustion …

Significant portions of oil in petroleum reservoirs remain unrecovered after the primary and
secondary production phases. To address this challenge, chemical Enhanced Oil Recovery …

This paper evaluates solvent-based nanofluids for in situ heavy oil upgrading during cyclic
steam stimulation (CSS) applications. The study includes a comprehensive analysis of the …
