WELL TELEMETRY SYSTEM (VARIANTS) AND METHOD FOR GEOPHYSICAL RESEARCH IN PROCESS OF DRILLING (VARIANTS) Russian patent published in 2007 - IPC G01V3/18

Abstract RU 2310215 C2

FIELD: geophysical well research, methods and devices for prospecting.

SUBSTANCE: invention claims well electromagnetic telemetric system with increased data transfer speed. An expression is suggested, which indicates that in case of actual decrease of frequency due to increase of phase condition number one can expect higher data transmission speed without expansion of frequency band.

EFFECT: disclosed system and method allow creation of stable efficient electromagnetic telemetric system with increased data transmission speed.
