This article presents core-flooding experiments on a Bazhenov Formation core sample designed to evaluate whether post-water methanol treatment can restore permeability. At reservoir conditions (110 °C, 23.5 MPa), the core was first water-flooded and then subjected to oil injection into the water-saturated rock, which caused severe, progressive permeability loss. NMR T1-T2 mapping captured fluid redistribution and the growth of bound/high-viscosity components. Gas chromatography indicated C36+-rich precipitates. A subsequent methanol flush stabilized the pressure drop and restored $\sim$87% of the pre-damage water permeability. These findings elucidate a water-oil-rock interaction pathway fo... More >

The ebulled bed hydrocracking technology of petroleum residues, called H-Oil, was invented in the 1950s. The first patent was issued in 1961. A demonstration unit was started up in 1963, and the first large-scale commercial unit was started up in 1968. There are currently 21 vacuum residue hydrocracking units operating worldwide using the ebulled bed reactor technology. Since 2015, the ebulated bed vacuum residue (VR) hydrocracking has been operated at the LUKOIL Neftohim Burgas (LNB) refinery. Performance of LNB ebullated bed vacuum residue H-Oil hydrocracker for a period of 10 years during processing 39 different vacuum residues at reactor temperatures between 408 and 434°C, and liquid ho...

This article explores the emerging concept of in situ hydrogen generation (ISHG) within oil reservoirs as a transformative pathway toward clean energy and hydrocarbon upgrading. With the global energy sector facing decarbonization pressures and limitations of conventional hydrogen production, ISHG offers a promising alternative by turning mature or depleted oil fields into subsurface reactors for hydrogen and upgraded oil co-production. Through thermochemical processes such as in situ combustion (ISC), steam methane reforming (SMR), coke gasification and water-gas shift reactions (WGSR), hydrogen is produced underground while carbon dioxide and by-products remain trapped, minimizing surface...
