Geological Applications: Measuring Dry Density in Boreholes for Hard Rock Gold & Copper Mining Geophysical borehole density logging in the hard rock mining sector, gold, copper, is becoming increasingly important in mine planning and ore body knowledge. Geological...
Formation Density Logging – Coal Blasthole Logging
BLASTHOLE LOGGING IN COAL BLASTHOLE LOGGING IN COAL PROJECT & GOALS: Identification of coal seam parameters (density, top boundary, bottom boundary and partings) within pre-split blastholes prior to blasting. BLASTHOLE LOGGING IN COAL DATA SETS: Gamma, dual spaced...
Formation Density Logging – Overview
DENSITY LOGGING DENSITY LOGGING APPLICATION: Measurement of the formation involves a small radioactive source (CS137 or CO60) acting as a gamma radiation source to induce back scattering of gamma radiation in the formation. The back scattered gamma energies are...
Spectral Gamma Logging – Uranium Logging Example.
SPECTRAL GAMMA LOGGING – URANIUM LOGGING EXAMPLE URANIUM LOGGING EXAMPLE PROJECT: The spectral gamma logging service was used on an Australian sedimentary uranium exploration project as part of an extensive geophysical logging suite which included total gamma,...
Spectral Gamma Logging – Overview.
SPECTRAL GAMMA LOGGING - OVERVIEW. SPECTRAL GAMMA LOGGING APPLICATION: Specific concentration analysis of the three main contributors to naturally occurring gamma radiation in rocks – Potassium (K40 1.46MeV), Uranium (Bi214 1.76MeV and Thorium (Th 2.61MeV). ...
Natural (Total) Gamma Logging – Inrod Logging & Regional Correlation
NATURAL (TOTAL) GAMMA LOGGING – INROD LOGGING AND REGIONAL CORRELATION. INROD LOGGING AND REGIONAL CORRELATION - PROJECT: Many mature mining provinces have a record of natural gamma logs from boreholes which have been used to establish a regional stratigraphy. One...
Natural (Total) Gamma Logging – Overview
NATURAL (TOTAL) GAMMA LOGGING - OVERVIEW GAMMA LOGGING APPLICATION: Measurement of the total naturally occurring gamma radiation. For the geological record the dominant contributors of gamma radiation are Potassium, Uranium and Thorium. It is the dominance of...
Nuclear Magnetic Resonance (NMR) – Near Surface Applications
<h4>Nuclear Magnetic Resonance NMR - Near Surface Applications</h4> A nuclear magnetic resonance (NMR) borehole logging technique has been developed for near surface mining, groundwater and environmental contamination projects. The NMR technique provides a...
Why use the services of a logging contractor?
<h4>Why use the services of a logging contractor?</h4> Geophysical borehole logging is a standard service in the mining, geotechnical, hydrogeological and environmental fields producing in situ physical rock properties rapidly and cost effectively. The...
Acoustic scanner (televiewer) versus 3 arm dipmeter
Borehole Imaging: Acoustic Scanner (Televiewers) versus 3 or 4 arm dipmeter. The acoustic scanner and 3 or 4 arm dipmeter probes have been used for coal exploration for a long time. It would be fair to say that the acoustic scanner has superseded the 3 or 4 arm...
