Patent ID: 7759943

Claim:
A method for determining subsurface properties, comprising: providing a resistivity imaging tool comprising an elongated body having a longitudinal axis and adapted for disposal within a subsurface borehole; a transmitter disposed on the body and adapted to transmit electromagnetic energy; and a receiver disposed on the body at a distance two inches (5 cm) or less from the transmitter and adapted to receive electromagnetic energy; wherein the transmitter or receiver comprises at least one antenna with its axis tilted with respect to the longitudinal body axis, wherein each transmitter and receiver comprises two antennas with their axes substantially orthogonal to one another, the transmitter antennas and the receiver antennas being arranged in the same orthogonal directions; and wherein the transmitter and receiver are both disposed in an insulating material within a cavity on the elongated body; disposing the tool within the borehole; energizing the transmitter to emit electromagnetic energy; acquiring a subsurface electromagnetic measurement using the receiver; and determining a subsurface property using the electromagnetic measurement.
