... Abstract Adsorption of polar crude oil components exert a major impact on chalk wetting, and adsorption effects have been reported on water-wet pure Stevns Klint outcrop chalk (>99% CaCO 3 ). Aalborg chalk is a silica-rich material also used as analogue rock material for chalk reservoir...

... is that the particles will improve the microscopic oil recovery efficiency of water flood in an oil reservoir. The concentrated solution of nanoparticles were prepared to 0.1 wt % concentration in synthetic North Sea water. Crude oil was obtained from a field in the North Sea. The following investigations were carried...

... studies propose different aging times which are significantly different in specific cases. This complexity can be explained by the variation in coreplug, crude oil, and temperature in the experiments( Dia et al. 1991 ; Graue et al. 2002 ; Graue et al. 1999 ; Yildiz et al. 1999 ). The effects of each...

... Abstract Migration of fines has been observed during water flooding in chalk reservoirs and has been suggested to play a key role in enhanced oil recovery (EOR). But, the exact role of fines is not well studied for carbonate reservoirs. This study shows that addition of water and crude oil...

... Based on the promising results with the partially coated titanium plate heat exchanger, it was decided to coat all 349 plates of an Alfa Laval M20 PHE. The PHE was installed offshore and put in operation for crude oil cooling. The PHE was installed approx. 1000 days of which it was operating...
