Abstract
A fluid is transferred between surface facilities and a subsurface reservoir formation through a well, which is equipped with a well lining having a permeability of less than 50 Darcy and preferably a lower permeability than at least part of the reservoir formation in the vicinity of the well lining so that fluid transfer into or from the formation is equalized even if the formation comprises strata having different permeabilities.
