Sedimentary rocks have the ability to hold oil, natural gas, and water due to physical properties called porosity and permeability. Porosity refers to the tiny air spaces in the rock itself. Permeability is a measure of the ability a rock to allow water, oil, natural gas, or other fluids to pass through it. In otherFile Size: KB. Measurement of magnetic susceptibilities of minerals and rocks by a simple induction device G. Alzetta, G. Villa Dipartimento di Fisica dell Universitá, Pisa, Italy and S.

An isotopic radiation transmission technique for quantifying the spatial distribution of porosity in sedimentary rocks is presented. A device was designed and constructed to examine rock samples of volumes sufficiently large for studying solute migration in rocks, so that a one-millimeter spatial resolution is attained with measurement acquisition time of one point per by: 2. Density and Specific Gravity defined Density is expressed in terms of mass per unit volume. The density of water, often used for comparisons, can be expressed as g/cm3 or 1, kg/m3. Mineralogists often use the unit-less measurements of specific gravity, which is the density of a mineral relative to that of an equivalent volume of water. A.
The present work involves a comprehensive experimental study of porosity and pore size distribution of sedimentary rocks, from oil fields formations, by means of two electromagnetic techniques, namely proton (1 H) nuclear magnetic resonance (NMR) and dielectric complex constant (DCC) as function of the frequency, both providing complementary Cited by: 8.

Bleifuss () and Mooney and Bleifuss () collected and published magnetic susceptibility and density data from a variety of Precambrian rocks throughout the state.
At about the same porosity the U. Geological Survey began acquiring magnetic susceptibility and NRM data in east-central and northeastern Minnesota. Density, porosity, and magnetic susceptibility of rocks from the Silver City 1 degree by 2 degrees Quadrangle, Arizona and New Mexico.

The mean magnetic susceptibility value for all rocks from the study area is x 10 -3 cgs, with a standard deviation of x 10 -3 cgs (appendix 3).Cited by: Petrophysical properties of rock samples from the Suhbaatar-Ulaanbaatar-Dalandzadgad geophysical profile in Mongolia are presented.
Based on the rock classifications and tectonic units, petrophysical parameters (bulk density, magnetic susceptibility, intensity of natural remanent magnetization, and Köenigsberger ratio) of these rocks are summarized.
Results indicate that (1 Cited by: 2. The current database consists of location 9, entries. The surface-based, point data include 5, 6, and density, magnetic susceptibility, and NRM measurements, respectively.
Downhole data from drillcore have also been incorporated, yielding an additional 1, and 9, measurements of density and magnetic susceptibility, respectively. DENSITY AND SUSCEPTIBILITY CHARACTERISATION OF MAJOR ROCK UNITS AND ROCK TYPES, MOUNT ISA INLIER JUNE I1 & I2 PROJECTS The following report compiles density and magnetic susceptibility measurements over the Mount Isa Inlier.
Data is based entirely on datasets some rocks in Table 1 is due to sampling from different populations. AFile Size: 2MB. Rocks made up of these minerals tend to be less dense due to porosity but with increasing depth of burial compaction reduces the porosity and most of the rocks comprising the crust of the Earth have a density between and The effect of density on porosity follows a mixing law.
The porosity, is the fractional pore volume of a Size: KB. PHYSICAL PROPERTIES. Physical property measurements made during Leg provided (1) sediment properties (density, porosity, natural gamma radiation [NGR], and magnetic susceptibility) to compare with composition, diagenesis, and consolidation history and to help constrain the location of unconformities, sediment fracturing, and fluid migration and expulsion.

Porosity in carbonate rocks results from many processes, both depositional and postdepositional. An understanding of these processes and of the textural history of porosity is necessary to a full appreciation of the history of the rock and is important in the location of potential hydrocarbon reservoir by: The effects of primary porosity on fluid flow during contact metamorphism were studied in basalts from central East Greenland.
The gabbroic Skaergaard magma intruded interbedded massive and aa basalts with mean macroscopic primary porosities of 4% and 11%, respectively. Grain density is measured by helium ideal-gas pycnometry, bulk density by the glass bead method developed by .
Porosity is calculated directly from bulk and grain densities. We also measure magnetic susceptibility, using an SM mag-netic susceptibility meter . Basalts: The low-Ti ( wt% TiO2) basalts measured here group tightly in. CC (Table 1) and in the mineralized black shales in the evaporitic section of Site (Core 39).
Dolomite occurs in small quantities throughout the cores and becomes prom-inent in or just above the evaporitic sequences. CALCULATION OF POROSITY, DENSITY, AND OTHER SEDIMENT PROPERTIES Data on water loss, interstitial salinity, and grain density.
Porosity and permeability Porosity and permeability are two of the primary factors that control the movement and storage of fluids in rocks and sediments. They are intrinsic characteristics of these geologic materials. The exploitation of natural resources, such as groundwater and petroleum, is partly dependent on the properties of porosity and permeability.
50%. Published porosity values of IDPs show similarly wide variation. WhileCorrigan et al. () reported porosity values between 0 and 10% (similar to that of larger chondritic meteorites),Rietmeijer and Nuth () report densities as low as g/cm3 for a few dust particles with porosities of up to 90%.Cited by:.

The following tables (from Telford et al, ) provides a very general guide to possible chargeabilities of materials. One reason that in-situ chargeabilities tend to appear lower than laboratory values is that large volumes of mixed materials are involved in .
