FIELD: mining.
SUBSTANCE: probe is delivered into a well crossing an underground formation, a circular area is isolated near the probe; a fluid is pumped from the circular area; at least one core sample is withdrawn from the underground formation in this circular space after it has been substantially filled with the formation fluid; and an electronic module is functionally connected to a coring device to ensure performance of at least one of actions including supply of power and transfer of communication signals.
EFFECT: increased efficiency and quality of core sampling.
