Present study demonstrates a two-stage integrated process for production of hydrocarbon oil designated as ALGLIQOL, with potential to be utilized as liquid transportation fuel. Stage-I involves in-situ catalytic hydrothermal liquefaction (HTL) of…
One of Sudanese fields has a heavy crude oil which has a high Total Acid Number (TAN) and high viscosity, can cause a lot of problems in production operation, transport, and storage facilities. The effect of ethanol dilution on the rheological…
Determining the physicochemical properties of petroleum is important for rapid decision-making during the production process. True boiling point (TBP) curve is the most important parameter in the petroleum characterization. However, the TBP can be…
The study areas of this PhD thesis are located in the Peruvian and Argentinean Andean Back-Arc in South America. The thesis focuses on two major themes: firstly, on contractional thick-skinned tectonics (and related processes, regarding interplay and…

This study aims to investigate a new method of combining ultrasonic waves with different frequencies and magnetic nanoparticles in reducing the asphaltene content and kinematic viscosity of heavy oil. In general, the experiments included irradiation…
Multiphase flow and complex flow regimes of asphalt-base crude oil with solid-state asphalt and gas presenting in submarine pipelines bring difficulty to the design and operation. For multiphase flow in risers, flow regimes are often very complex. So…
