Abstract
Abstract: Determining a True Textural Permeability
by Modeling Key NMR Outputs Using
Only Conventional Log Data
By
Nu-Tech Energy Alliance
Humble, Texas
In the ongoing research and development process to enhance
formation evaluation, establishing a relationship to permeability
has always been a key goal. In the early 1990’s the commercialization
of 
nuclear
magnetic resonance (NMR) logging in the oil
and gas industry provided the first such link through the direct
measurement of the fluid volume and the distribution of that
fluid in the rock.
This link to permeability set the stage for several refinements in NMR over the last decade, the results of which have dramatically shaped how the industry views bypassed pay. By utilizing conventional log data, textural or pore size changes within the reservoir can be detected and modeled. These models allow companies to take a new look at fields that have not had the benefit of such NMR measurements
