Abstract:
1. A method of calibrating a multi-component induction logging tool, comprising: orienting a first sub including a Z-transmitter coil so that a direction of operation of the Z-transmitter coil on the first sub is substantially orthogonal to a direction of operation of at least one Z-receiver coil on a second sub and so that the first sub is at least partially encompassed by the second sub, and wherein the Z-transmitter coil, an X-transmitter coil on the second sub, and the at least one Z-receiver coil are encompassed with at least one conducting loop of a calibrator, the first sub and the second sub being detachable parts of a multi-component induction logging tool; positioning the multi-component induction logging tool such that a direction of operation of the X-transmitter coil on the second sub is substantially parallel to a conducting surface exterior to the tool, wherein the length of the conducting surface is greater than an axial length of the second sub; and using the calibrator to calibrate the multi-component induction logging tool.
