METHOD AND DEVICE FOR AUTOMATIC RECOVERY OF WELL GEOMETRY BY MEASUREMENTS OF LOW-FREQUENCY ELECTROMAGNETIC SIGNALS Russian patent published in 2015 - IPC G01V3/30 

Abstract RU 2543699 C2

FIELD: measurement equipment.

SUBSTANCE: invention relates to geophysical measurements in a well. Substance: the method includes development of a model for forecasting of measurements, which are produced by receivers due to transmissions with the help of sources, on the basis of estimated positions of receivers relative to sources. Estimated positions have at least two measurements. At least some of receivers and sources are placed in a well. On the computer the estimated positions are automatically confirmed on the basis of comparison of forecast measurements and actual measurements, which are produced with the help of receivers.

EFFECT: increased accuracy of measurements.
