Geological Applications: Environmental Contamination “Knowledge of your target’s physical properties will aid in the selection of the most applicable geophysical logging method for your drill program.” Environmental contamination investigation and monitoring projects...
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 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 - 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...
<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...
<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...
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 It would be fair to say that the acoustic scanner has superseded the 3 or 4 arm...
<h4>Borehole Geophysics in Universities</h4> Should more attention be given to borehole geophysics in undergraduate geology and/or geophysics courses? <h4>Borehole Geophysics</h4> Borehole Geophysics (also known as geophysical logging, downhole...
<h4>Managed Aquifer Recharge Schemes</h4> An interesting presentation at a recent groundwater forum showed the increasing popularity (in the arid conditions of South Australia – a necessity) of Managed Aquifer Recharge schemes. <h4>What is...
Deconvolution of gamma logs Deconvolution is a common process in seismic process where the objective is to “sharpen” the seismic response at depth. The process is necessary as the earth through which the seismic source pulse travels is altered by the rocks which act...
