Combinations of axial and saddle coils to create the equivalent of tilted coils for directional resistivity measurements

An electromagnetic well logging instrument includes an instrument housing, at least one transmitter coil disposed on the housing and at least one receiver coil disposed on the housing. At least one of the transmitter and receiver coils is formed from a combination solenoidal (axial) and saddle coils...

description	An electromagnetic well logging instrument includes an instrument housing, at least one transmitter coil disposed on the housing and at least one receiver coil disposed on the housing. At least one of the transmitter and receiver coils is formed from a combination solenoidal (axial) and saddle coils. The net dipole moment direction of the combined coil is determined by selecting the relative turn-areas of the saddle and solenoidal coil. The combined coil can be formed from a single wire wound to have both a longitudinal magnetic dipole moment and a transverse magnetic dipole moment with respect to a longitudinal axis of the housing.
