ABSTRACT:
The invention describes a method of cement lining a wellbore to enable a fixed sensor internal of the lining to sense characteristics of the external formations surrounding the wellbore using, at the region of the sensor position, a permeability changing device before completion of setting of the cement to create, in use, a permanent fluid communication through the cement lining between the external formation and the sensor.
