Characterization of Asphaltene Deposition Behavior in Diluted Heavy Oil under High-Pressure Conditions

Energies, 2023
Some oil wells in the Tahe oilfield have been reported to produce extremely heavy oil due to asphaltene deposition. To enhance the flow of crude oil through the wellbore, engineers adopted the use of light oil from nearby wells to dissolve the heavy ...

Fractured petroleum reservoirs [PDF]

, 2000
Total compressibility in a fractured reservoir is estimated using the pressure response due to gravitational potential variations. Both the moon and the sun gravitational potentials are accounted for using the full expression by inclusion of longer-period components. The semi-diurnal and diurnal pressure data show substantial long-term variations.
