Abstract
A method for transforming an earth formation and/or production equipment based on correcting nuclear magnetic resonance (NMR) data to account for partially water-saturated rock includes: receiving NMR logging data having echo-trains for an earth formation; inverting the echo-trains to provide transverse relaxation time constant (T) distributions for various components of fluid in the earth formation; substituting a Tdistribution for mobile water of fully water-saturated rock for a Tdistribution for mobile water of partially water-saturated rock based on values of the mobile water Tdistribution of partially water-saturated rock and a total porosity constraint; summing the Tdistribution for mobile water of fully water-saturated rock and a Tdistribution for an immobile water component of the fluid to provide a T, distribution for fully water-saturated rock; and transforming the earth formation and/or the production equipment based on a parameter derived from the Tdistribution for fully water-saturated rock.
