FIELD: oil and gas industry.
SUBSTANCE: invention refers to transporting samples of fluid mediums and/or rheological measurements to surface of division. According to one of versions the method consists in circulating heated fluid medium in the first region of the reservoir bed wherein a composition of heavy oil is present or considered present with implementation of a pump assembled on the surface and an installation for well completion containing a well pump and a sampling tool within the period of time and at consumption adequate for obtaining fluid composition of heavy oil; then sampling of fluid composition of heavy oil is performed by means of the sampling tool.
EFFECT: facilitation of sampling from reservoir bed by means of device or its part used for supply of heat into reservoir bed region in question.
