Abstract
A nuclear magnetic resonance (NMR) logging tool configured to be positioned in a borehole created in a subsurface formation. The NMR logging tool includes a magnet to induce a magnetic field in the subsurface formation, a transmission line, and a first shield positioned between the magnet and the transmission line. The NMR logging tool includes a transmitter and an antenna coupled to the transmitter by the transmission line. The antenna is to transmit a radio frequency (RF) magnetic field into the subsurface formation in response to the transmitter supplying power by the transmission line.
