Abstract

A method for transforming an earth formation and/or a completion component for the earth formation based on estimating a parameter of the earth formation includes: performing a nuclear magnetic resonance (NMR) experiment on the earth formation, the NMR experiment includes transmitting an initial radio-frequency (RF) pulse and a series of refocusing RF pulses; detecting a truncated free induction decay (FID) signal following the initial RF pulse and a spin echo following at least one refocusing RF pulse, the truncated FID signal missing an initial part of a total FID signal; reconstructing the total FID signal using the truncated FID signal, the detected spin echo, and a calculated or measured time between end of transmitting the initial RF pulse and beginning of receiving the truncated FID signal; estimating the parameter using the total FID signal; and transforming the earth formation and/or the completion component based on the estimated property using transformation-equipment.
