Patent ID: 6972564

Claim:
A method of using am NMR instrument conveyed in a borehole the method comprising: (a) defining a petrophysical objective for use of the NMR instrument; (b) defining at least three building blocks including: (i) a first building block of a sequence of trainlets, each trainlet having an excitation pulse and at least one refocusing pulse, and (ii) at least two additional building blocks of pulse sequences, each of said at least two additional building blocks comprising an excitation pulse and at least one refocusing pulse and having a duration longer than a duration of one of said trainlets; (c) based on said petrophysical objective, selecting said first building block and at least one of said at least two additional building blocks and defining therefrom an acquisition sequence; and (d) using said defined acquisition sequence on said NMR instrument and producing signals.
