Abstract:
Various embodiments include a method for configuring and generating a non-adiabatic saturation pulse for use in nuclear magnetic resonance (NMR) logging. One such method configures the pulse by adjusting one or more of pulse amplitude modulation or phase cycling. The modified pulse is transmitted into a fluid such that a substantially uniform nuclear spin saturation or nuclear spin inversion echo response is received from the fluid. A wait time between the pulse transmission and the echo response that indicates that spin equilibrium has been achieved is substantially equal to a T 1  time. The wait time is an indication of the characteristics of the fluid.

Claim (Index 8):
The method of  claim 7 , further comprising:\n transmitting the modified non-adiabatic pulse into a fluid in a geological formation; waiting a time period after transmitting; transmitting, after the time period, a readout pulse sequence based on the non-adiabatic pulse; receiving the echo response from the fluid; determining from Bloch's equations if the echo response indicates nuclear spins have recovered to equilibrium; incrementing the time period and repeating the transmitting the readout pulse sequence and receiving the echo response until Bloch's equations indicate that the nuclear spins have recovered to equilibrium at a final wait time; and determining characteristics of the fluid based on the final wait time.
