Formation of methane hydrate in Bentheim sandstone was monitored in situ with magnetic resonance imaging (MRI). Sequestration of CO 2 in hydrate accumulations was achieved by exposing the hydrate to liquid CO 2 . The spontaneous exchange of methane w

Complementary imaging techniques used to study enhanced oil recovery (EOR) processes in fractured oil reservoirs have provided new and improved fundamental understanding of how oil recovery is affected by fractures. The combination of two imaging tec

Summary Magnetic resonance imaging (MRI) of core samples in laboratory experiments showed that CO2 storage in gas hydrates formed in porous rock resulted in the spontaneous production of methane with no associated water production. The exposure of me

The in situ saturation development for reservoir core plugs was monitored during spontaneous imbibition using magnetic resonance imaging (MRI). The images monitored the movement of the imbibition front and the saturation change across the front as a

Alteration of the wettability is often a part of the restoration process for core plugs or used to obtain a desired wettability in outcrop plugs. If the procedure does not provide a uniform wettability state in the plug, experimental artifacts can re

Summary Iterative comparison between experimental work and numerical simulations has been used to predict oil-recovery mechanisms in fractured chalk as a function of wettability. Selective and reproducible alteration of wettability by aging in crude

Summary A total of 41 chalk core plugs, cut with the same orientation from large blocks of outcrop chalk, have been aged in crude oil at 90 °C for different time periods, in duplicate sets. Different filtration techniques, filtration temperatures an

Summary The effect of embedded fractures on the movement and recovery of hydrocarbon from larger outcrop chalk blocks at different wettabilities has been measured in the laboratory. Two-dimensional (2D) nuclear tracer imaging was used to produce in s

The effect of a novel CCKA receptor antagonist 2-naphthalene sulphonyl-L-aspartyl-2-(phenethyl)amide, sodium salt (2-NAP) on the reduction of food intake induced by exogenous CCK, administered centrally or peripherally, has been examined in pigs. 2-N
