Digital drill core logging

Good Day,

Ever wondered if modern civilization could exist without our being able to examine drill core samples of the deep subsurface?

How many institutions offer courses that would enable their undergraduate geologists and engineers to tackle this question – even though the massive mines and colossal civil structures we see today rely heavily on the accuracy and quality of data logged from drill core?

Clearly we owe much to the invention of the diamond drill in 1863. Yet, despite the fact that drilling technology, together with the analysis and computer modelling of drill core data, has made significant advances – on many projects drill core logging is still a ‘pen and clipboard’ exercise, generating reams of paper files to be ‘captured’ in a database.

Hence the question – is there a digital logging system that can, as a minimum:

• Be deployed rig-side initially to ensure that critical rock mass features, which rapidly deteriorate, such as weak rock zones and soft joint fills, are properly recorded?
• Enable loggers to examine the core in detail and concentrate solely on accurate description of the lithological intervals and structures intersected – without worrying about measuring up the core?
• Allow the accurate depth and angle measurement of each interval and structure respectively to be undertaken offsite by trained technicians, so as to complete the logs?
• Export the logs directly to a database?

 
The answer is “Yes” – using proprietary StereoCore™ technology.
 
The latest version of StereoCore Photolog can be installed on a Windows 10 Tablet so that core tray photos can be processed and the images marked up rig-side, using data markers to pinpoint features and log their descriptors. Copies of the files can then be distributed for detailed logging in the core shed, followed by depth registration and structure angle measurements, after which the files are merged to generate the logs and export the data in Excel or CSV files.
 
Every effort has been put into ensuring a smooth and painless transition to StereoCore Photolog, by enabling customers to digitally re-create their existing tried and tested log tables using their own lookups, etc. and, if needed, in their own language using our purpose designed LogFormatEdit.
 
We invite you to see for yourself how streamlined and intuitive this process is, and how flexible and powerful your data capture, analysis, and presentation with StereoCore Photolog can be.
 
Please contact us at support@stereocore.net in order to:

• book a live 10 minute interactive SKYPE demo of the software, with plenty of time for discussion afterwards,
• arrange free activations of the software for your working trials in order to test the program with your current logging, or archived core photographs – universities can arrange for special dispensations,
• ask any questions or obtain additional information.

 
Yours in logging,
John Orpen
