Claim 14:
15. A method of installing the device of claim 14 in a hydrocarbon reservoir, comprising:
a) expanding the biasing device until the biasing device is in contact with the formation;
b) expanding the biasing device until the hydrophilic membrane is pushed against the reservoir formation with a force (F) which is equal to or greater than the pressure difference (P) between a hydrocarbon phase (Po) and the water phase (Pw) multiplied with the surface area (A) of the contact surface of the hydrophilic membrane;
whereby
the hydrophilic fluid from the reservoir is injected through the hydrophilic membrane and into the formation, either before or after step a) but before step b).
