Abstract


Permeability is one of the most important petrophysical

parameters to describe the reservoir properties of

sedimentary rocks, pertaining to problems in hydrology,

geothermics, and hydrocarbon reservoir analysis. Outcrop

analogue studies, well core measurements, and individual

sample analysis take advantage of a variety of commercially

available devices for permeability measurements. Very often,

permeability data derived from different devices need to be

merged within one study (e.g. outcrop minipermeametry and

lab-based core plug measurements). To enhance accuracy

of different gas-driven permeability measurements, devicespecific

aberrations need to be taken into account. The application

of simple one-to-one correlations may draw the wrong

picture of permeability trends. For this purpose, transform

equations need to be established.

This study presents a detailed comparison of permeability

data derived from a selection of commonly used Hassler

cells and probe permeameters. As a result of individual crossplots,

typical aberrations and transform equations are elaborated,

which enable corrections for the specific permeameters.

Permeability measurements of the commercially available

ErgoTech gas permeameter and the TinyPerm II probe

permeameter are well-comparable over the entire range of

permeability, with R2 = 0.955. Aberrations are mostly identified

in the permeability range <10 mD, regarding the

TinyPerm II and the minipermeameter/Hassler-cell combination

at Darmstadt University, which need to be corrected

and standardized. Applying standardizations which consider

these aberration intervals strongly improves the comparability

of permeability data sets and facilitates the combination

of measurement principles. Therefore, the utilization of such

correlation tests is highly recommended for all kinds of reservoir

studies using integrated permeability databases.
