A catalog of porosity and permeability from core plugs in siliciclastic rocks

Abstract

Porosity and permeability measurements on cored samples from siliciclastic formations are presented for 70 data sets, taken from published data and descriptions. Data sets generally represent specific formations, usually from a limited number of wells. Each data set is represented by a written summary, a plot of permeability versus porosity, and a digital file of the data. The summaries include a publication reference, the geologic age of the formation, location, well names, depth range, various geologic descriptions, and core measurement conditions. Attributes such as grain size or depositional environment are identified by symbols on the plots. An index lists the authors and date, geologic age, formation name, sandstone classification, location, basin or structural province, and field name.

Monte-Carlo Based Numerical Modeling and Simulation of Criticality Conditions Occurrence in Natural Reactor Zone 9 in Oklo Deposit (Gabon)

“…Realistic rock porosity in such sandstone rock reservoir may therefore range from 20% to 40%. 17) This can clearly be observed in the zones 7 to 9 which show important quantities of the degraded O.M. 8,12,22) The operating time of the reactor n°9 is estimated to 220,000 years.…”

How well can we predict permeability in sedimentary basins? Deriving and evaluating porosity–permeability equations for noncemented sand and clay mixtures

“…While large compilations of permeability data have been published (Neuzil 1994;Nelson & Kibler 2001;Ehrenberg & Nadeau 2005;Wilson et al 2008;Yang & Aplin 2010), the Roer Valley Graben and London Clay datasets are to our knowledge the only available datasets that combine detailed porosity, permeability, grain size, and clay content data, as well as some constraints on the mineralogy of the clay fraction. Both datasets consist of sediments that were buried less than 2 km deep and therefore have not been affected significantly by diagenesis.…”

Geologic framework for the national assessment of carbon dioxide storage resources: U.S. Gulf Coast

“…Despite relatively deep reservoirs, Norphlet Formation porosity is described as excellent (Bolin and others, 1989;Dixon and others, 1989). Published porosity and permeability values (Badon, 1975;Mancini, 2010) were compared to sandstone analogs (Nelson and Kibler, 2003;Ehrenberg and others, 2009), and average field values obtained from Nehring Associates, Inc. (2010) for the U.S. Gulf Coast study area were used for additional comparison. Based upon a review of these published results, the Norphlet Formation SAU C50490101 was assigned an average porosity range from 10 to 18 percent and a permeability range from 10 to 1,000 millidarcies (mD).…”
