FIELD: construction.
SUBSTANCE: method of well distance determination is proposed, comprising: drilling a first wellbore comprising an elongated conductive body; installing an electric field sensor in a second wellbore; inducing current along the first wellbore, as a result of which the electromagnetic field is emitted from the first wellbore; receiving the electromagnetic field with the use of the electric field sensor. The electric field of the electromagnetic field is measured, and using the measured electric field for calculating thereby: the orientation of the first wellbore and the distance between the first and the second wellbore, or the direction of the first wellbore relative to the second wellbore.
EFFECT: expanding the arsenal of technical means for determining the distance between the wells.
