Core scanner for examination of cores in boxes with the possibility of their conveyor loading.

BoxScan is a mobile unit where it is possible to study core samples in boxes. The BoxScan core scanner solves the problem of time-consuming acquisition, comparison and analysis of rock data by automated and simultaneous collection of geochemical and geophysical parameters of the core using one easy-to-use scanning system. The system is small, does not require cooling, and uses robust technology to deliver results in near real time in field. 

BoxScan requires only one field technician, who can acquire up to 7 different datasets automatically without interacting with the sample, which reduces measurement and human errors. This system can be equipped with sensors for measuring: chemical and mineralogical composition, point magnetic susceptibility. The GeoScan V line-scanning camera for high quality core images is supplied with the instrument base. Below there is an example of data visualization (the process of obtaining data is on video in the section "Technique").

This example demonstrates photographing a dry and a wet sample using a GeoScan V line scan camera from Geotek, magnetic susceptibility data and their correlation with rock color and geochemical data (Olympus handheld XRF). All data are perfectly correlated with each other due to the fact that, firstly, data are collected at the same points of the sample, and secondly, all information received by sensors is recorded relative to depth.

Due to the small size BoxScan system is the most suitable option for the mining industry and for surveying in the fields. The ability to study several cores at once is especially important in cases where a high throughput of the system is required with minimal operator involvement. Therefore a 24 hour core logging operation is more efficient using a BoxScan without the need for night shift technicians thus saving customers money in the long term. Portable XRF analyzers, IR spectrometers and high-resolution cameras are often used for working in core storage. Measurements with these instruments are usually done manually and at long intervals, which is time consuming. BoxScan system allows you to combine all these devices on a single base and receive all the necessary data automatically and that gives a possibility for user to free time for other tasks. Any core collected for a science or engineering application can benefit from the high resolution, continuous, non-destructive core analysis offered by the MSCL. The multi-sensor arrangement of the MSCL uniquely allows users to confidently compare micro and macro scale changes in physical and chemical properties downcore. The obtained information will be useful to specialists from a wide variety of fields.

Oil and gas industry:

  • Correlation and binding of core data to logging results;
  • Quantitative and qualitative analysis of core heterogeneity;
  • XRF analysis to obtain data on the elemental composition of the sample;
  • Obtaining mineralogical maps and natural gamma-activity of rocks for further analysis of reservoirs;
  • Clustering based on data from several sensors.

Mining industry:

  • Data on the elemental composition of samples for assessing reserves;
  • Identification of target horizons;
  • Determination of lithological units and their properties;
  • Instantaneous analysis of samples and their description in field.

Work in the core storage:

  • Fast and high-quality analyzes of core material;
  • High-resolution optical scanning for material cataloging;
  • Increasing the economic efficiency of work by obtaining additional data;
  • Additional study of archived core and refinement of well data.

Geotek MSCL-XYZ multisensor core scanner parameters:

  • System dimensions (LxWxH, cm): 220 х 140 х 185;
  • System weight (kg): 960;
  • Sample parameters: length up to 155 cm, diameter 5-15 cm (loading up to 10.5 m of core for one complete measurement);
  • Sensor movement: fully automated and software controlled movement of sensors along the horizontal and vertical axes X and Z (linear accuracy 0.02 mm, data is collected simultaneously), as well as a platform moving along the Y axis, on which boxes with core are placed;
  • Data output: ASCII files containing all measured parameters associated with depth.

Parameters of sensors installed on the Geotek MSCL-XYZ system:

  • Magnetic susceptibility: point sensor (operating frequency 2 kHz);
  • Photo documentation: full-color digital linear scanning system (resolution up to 20 microns, maximum scanning speed 200 lines/sec) with ability to install UV-light;
  • X-ray fluorescence analysis: portable XRF Olympus Vanta (detectable elements Mg-U);
  • Mineralogical composition: VNIR/SWIR spectrometer (spectral range 780-2500 nm).

The BoxScan Core Scanner is a platform with open sides and a front for easy loading of core boxes, as well as mountings for sensors, electronics and mechanisms located inside. The user loads the box with the core onto the device platform, after which, using the software, sets the measurement parameters in accordance with the actual tasks. Then the system starts to carry out the specified measurements. The sensors move along the X and Z axes, making respectively horizontal movements with a given step and vertical movements of the arm with sensors and sensors, in order to ensure their safety and prevent their horizontal impact with the sample. The user sees in real time both the measurement process itself and the results that are displayed on the monitor. At any time you can stop measurements and change parameters, or change samples. All actions are as automated and safe as possible and require minimal operator involvement. Further, in the video, the whole process of the BoxScan core scanner is clearly presented, and, as we can see, the core in this video is not consolidated, which once again confirms the versatility of the installation and its applicability for a variety of samples and tasks.
