In-situ combustion has received much attention in the last few decades for enhanced heavy
oil recovery processes. Although a wide part of research efforts has only focused on the …

Heavy oil resources are attracting considerable interest in terms of sustaining energy
demand. However, the exploitation of such resources requires deeper understanding of the …

This work deals with the reactivity and structural changes of asphaltenes during cracking in
supercritical water using water-soluble salts Co and Ni. Cracking of the asphaltenes was …

During steam injection processes, oil-soluble catalysts have demonstrated high efficiency by
improving the flow properties of heavy crude oil into the reservoir. In order to gain a deeper …

The increasing energy consumption has made heavy oil more and more important in world
energy system. However, the exploitation of heavy oil is still very challenging due to the high …

Background Water-soluble polymers are increasingly attracting the attention of petroleum
engineers for their excellent surface activity and viscosity-reducing properties in enhancing …

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 …

In this work, the catalytic performance of a synthesized dispersed Ni-based catalyst
[amorphous catalytic system of Ni (NO3)(OH)] in the hydrothermal upgrading of high-sulfur …

In this work, the effect of synthesized Ferrocene-based ligand catalysts, including Mono-, Di-
and Tri-Ferrocene, as additives for promoting the catalytic in-situ hydrothermal upgrading of …

This research tries to figure out the role of water as a green and environmental hydrogen-
donor solvent for catalytic and non-catalytic hydrothermal desulfurization (HT-DS) of …
