Abstract:
RCP pulses are used to calibrate an NMR logging tool with a quadrature antenna. Using a number of RCP pulses provides NMR signals that can be used to find optimal positioning for antennas on the quadrature antenna. Optimally positioning antennas provides accurate values for NMR signal measurements. Employing an optimally positioned quadrature antenna readily enables the NMR logging tool to produce CP pulses and RCP pulses.
