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.
