Reservoir rock in general have very complex permeabilities for oil and water.
The permeability can and will change from area to area for a whole number of rea-
sons. Only laboratory experiments on multiple cores at the reservoir conditions
allow to develop an accurate understanding of the reservoir processes and with cer-
tainty maximize oil extraction.
