PROCESS OF ELECTROMAGNETIC LOGGING OF HOLES Russian patent published in 1996 - IPC

Abstract RU 2069879 C1

FIELD: mineralogy. SUBSTANCE: process is intended for isolation of productive seams-collectors. In agreement with process electromagnetic field is excited in two mutually perpendicular azimuths. Damping of vertical component of magnetic field is recorded. Presence of inclined cracks in collectors is judged by presence of damping of component of magnetic field of at least one of generator coils. EFFECT: increased reliability of process. 2 dwg
