Beschreibung
Zusammenfassung:	This invention relates to the oil and gas production industry and can be used in geophysical surveys of horizontal and deviated (including vertical) wells for their injectivity profiling and assessment of total fluid loss into the lower zone of a target interval, inaccessible for survey, and below the bottom hole.The proposed technology can be used in the presence of both behind-casing and wellbore cross-flows.
