The present invention provides methods and systems for making measurements associated
with a rock formation including a main borehole, a microborehole extending from
the main borehole into the rock formation, and one or more sensing devices positioned
and arranged to make a measurement at measurement zones being located in the microborehole.
A packer can also be installed in the microborehole dimensioned and arranged to
hydraulically isolate the measurement zones from conditions present in other parts
of the microborehole and/or main borehole. Methods and systems are also provided
for taking fluid samples and injecting fluid tracers in a microborehole.
