Abstract:
A nuclear magnetic resonance (NMR) logging tool includes a pulsed magnetic field source which provides an NMR logging pulse sequence having a reduced interecho interval (TE). A controller in communication with the pulsed magnetic field source provides a pulse sequence designed to substantially align an echo peak with a measurement deadtime boundary, yielding a partial spin echo data recovery which is at least partially compensated by a substantially higher measurement density.
