Abstract

A method and system for determining the volume of a drill core sample, wherein the method comprises the steps of providing a reference surface of a core tray adapted to carry at least one drill core sample, placing a drill core sample in the core tray, scanning the core tray with an electromagnetic 3D scanner to obtain a sample surface, and computing the volume of the drill core sample by comparing the sample surface with the reference surface. Scanning the sample will provide accurate and repeatable measurements even for drill core samples with non-cylindrical segments.

Abstract

A System for collecting and processing data concerning physical features of drill core samples with three-dimensional shape and appearance. The system comprises a contact less analytical apparatus for measuring and collecting data of at least some part of the outer surface of the drill core samples, a first data-storing means for storing data collected by the analytical apparatus, a processing unit that applies one or more data evaluation algorithms on the data stored in the first data storage means in order to extract data regarding physical features of the drill cores (1) as an output, and a second data storage means for storage of the resulting output from the processing unit. The system is also related to a method for measuring and collecting data on the three-dimensional shape and appearance of drill core samples, such as planar discontinuities including orientation marks on the drill core samples.
