Estimation of petrophysical and fluid properties using integral transforms in nuclear magnetic resonance

摘要

Apparatus and method of characterizing a subterranean formation including observing a formation using nuclear magnetic resonance measurements, calculating an answer product by computing an integral transform on the indications in measurement-domain, and using answer products to estimate a property of the formation. Apparatus and a method for characterizing a subterranean formation including collecting NMR data of a formation, calculating an answer product comprising the data, wherein the calculating comprises a formula; $$ K\&\#x2061;\left(x\right)\&\#x2261;{\int }_0^{\infty }\&\#x2062;k\&\#x2061;\left(t\right)\&\#x2062;e^{-t/x}\&\#x2062;\mathrm{dt}.$$and estimating a property of the formation using the answer product.
