“…TinyPerm-derived permeabilities obtained from the the highly permeable Navajo Sandstone were found to be 1.8 times higher than plug-derived permeability values (Fossen et al, 2011;Torabi and Fossen, 2009). Sutherland et al (1993) discuss not only the advantages but also limitations of probe permeametry, emphasizing the need of standardized experimental conditions.…”

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 R 2 = 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.

“…Compared to permeability of water, gas permeability is easier to measure, requires less time and produces more reproducible result [7]. The flow of a fluid (laminar flow) in a porous solid is described by Darcy's law [4] and for a probe permeametry the permeability is calculated from a modified Darcy's equation [1].…”

A B S T R A C T R I~ S U M I~Architecturally appropriate and technically effective conservation and maintenance of historic masonry requires meaningful characterisation of existing materials. Sampling from important historic monuments is often not alowed, so there is a need for non-destructive in-situ test. Portable probe gas permeability, developed for use in petroleum reservoir studies, has the clear potential for application in practical conservation. In particular the application of gas permeametry in-situ may help in the study of weathering and decay of historic masonry materials. A pilot experiment was carried out to evaluate the applicability of steady state portable probe permeametry for the in-situ characterisation of historic natural sandstone masonry. The in-situ surface gas permeability of recently cleaned and original un-cleaned ashlar sandstone masonry was compared and the repeatability and variability of the measurements was evaluated. The method was found to be capable of assessing the permeability contrast of the cleaned and un-cleaned sandstone, though some limitations of the test method were identified. La pr&ervation architecturale et technique appropri&s ainsi que l'entretien des mafonneries de monuments historiques exigent la caract&isation pertinente des mat&iaux existants. Cependant, l'&hantillonnage des monuments historiques n'~tant pas souvent autoris~, un besoin urgent d' essais non-destructifs in-situ

“…The geometrical factor, when calculated numerically for a given sample and probe geometry, accounts for the complex multidimensional flow pattern throughout the porous medium, capturing the edge effects associated with the geometry of the sample and probe, and thus boundary conditions that are simply not accounted for by an empirical calibration using core plugs. This can be particularly true when using a calibration relationship [Robertson and McPhee, 1990;Sutherland et al, 1993] to solve for permeability on a sample with a strongly differing geometry or size than that of the core plugs used in the calibration exercise.…”

[1] Considerable heterogeneity is evident when permeability measurements are made on small scales, either in the field or in the laboratory on field samples. Small-scale permeability measurements have commonly been made by inducing multidimensional gas flow through a sample with various configurations of the conventional surface-sealing gas minipermeameter. In order to reduce weathering and seal-quality problems, a new minipermeameter probe was designed for field application within small diameter holes drilled into an outcrop. We briefly describe the small drill hole minipermeameter, while developing in detail the associated data analysis methodology for performing in situ permeability measurements with this new probe. Analysis of field data, which consists of gas injection pressure and mass flow rate, is based on a numerical solution in cylindrical coordinates of the ideal gas flow equation, assuming homogeneous and isotropic conditions over the averaging volume of the measurements. In the following development the semianalytical inverse solution for permeability will be derived for the new small drill hole minipermeameter probe, which varies from that of the conventional surfacesealing minipermeameter probe only in the choice of the appropriate characteristic length and in the magnitude of the associated geometrical factor.
