METHOD AND APPARATUS FOR FORMING IMAGES BASED ON RESISTIVITY METHOD DATA IN WELLS FILLED WITH LOW-CONDUCTIVITY WELL FLUID Russian patent published in 2012 - IPC G01V3/30

Abstract RU 2462735 C2

FIELD: physics.

SUBSTANCE: logging device has at least one antenna, having a vertical axis, and at least two electrodes spaced apart in the azimuthal direction. The antenna is placed between the two electrodes. The device also has a processor which is capable of powering one of the components, including at least one antenna and at least two electrodes, for generating electric current in the rock, and using a signal which is sensitive to electric current generated by the other of said components in order to determine resistivity of the rock.

EFFECT: measuring horizontal resistivity of rocks.

20 cl, 13 dwg
