Evolution of Pore Structure and Permeability of Rocks in Laboratory Experiments
Rock strength is profoundly affected by pore fluids through diverse mechanical and chemical interactions (Walder and Nur, 1984; Carter et al., 1990)....

FICUS, a new in-situ probe for resistivity measurements in unconsolidated marine sediments
Physical properties of shallow sediments measured at a particular site can not easily be extrapolated over a given profile. The number of samples...

Techniques for Improving the Oil Recovery
We have seen in preceding chapters that not all of the hydrocarbon contained in a reservoir can be extracted. The basic resource, therefore, cannot...
