Borehole Imaging - Optical Scanner - Overview. Application: The optical scanner is a high resolution CMOS camera borehole imaging probe which is commonly run in combination with an acoustic scanner for detailed, high resolution images of the borehole through...
LOGGING UNIT DESIGN OVERVIEW: In the slimhole logging market, there are a wide range of vehicle based logging unit designs aiming to provide an efficient, safe and cost effective service. The design needs to cover a number of factors which can occur during everyday...
BOREHOLE IMAGING: ACOUSTIC SCANNER APPLICATION: The acoustic scanner is an ultrasonic borehole imaging probe which is commonly run in combination with an optical scanner for detailed, high resolution images of the borehole through 360°. Ideal and commonly used for...
Borehole Density Measurements - Geophysical Logging OVERVIEW: Geophysical borehole density logging is a rapid, cost effective and accurate method to obtain bulk density values for ore modelling. In many mineralisation styles, the density value can be related to the...
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...
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 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 – 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 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...
