FIELD: oil and gas production.
SUBSTANCE: inductive logging is performed along borehole of well with instrument containing at least one transmitter and multitude of receivers spaced from transmitter along borehole of well. Efficient permeability of formation is determined directly near the borehole of the well by measurements made with the inductive receiver nearest to the inductive transmitter. Efficient specific permeability of formation is used for correction of measurements of apparent specific permeability made at least with one inductive receiver in the instrument.
EFFECT: simplification.
