CoalLog – The Australian Coal Logging Standard v2.0

Before CoalLog, approximately 30 different data formats and over 100 different data code translation tables were being used in the capture of geological and geotechnical data throughout the Australian Coal Industry. Additionally, each of the major Australian geological software companies uses different conventions for the transfer of data. These different formats, dictionaries, and transferral conventions, have led to major inefficiencies in the collection, transfer, and analysis of coal borehole data throughout Australia.

During the period 2010-2012, three sub-committees (geological, geotechnical, and data transfer) with representatives from most major Australian coal mining, consulting, and software companies developed 'CoalLog' which includes data entry sheets and standard code lookup tables for header, drilling, lithology and geotechnical data as well as a format for the transferal of this data.

This new Standard was completed and delivered to industry in February 2012 with financial support from ACARP. The original version was updated with v1.1 in September 2012, v1.2 in November 2013 and v2.0 in April 2015. Further improvement and development to the Standard is planned and feedback is welcome via CoalLog@ausimm.com.au.

As well as minor updates to logging sheets and dictionaries, CoalLog v2.0 includes the new features of a Borehole Logging Training Manual, new logging sheets for recording Drilling data and standard plotting patterns for all Lithotypes and Lithology Qualifiers defined in CoalLog.

The New South Wales state government department responsible for archiving coal exploration data has decided to adopt the Standard and will be encouraging companies to provide their data in 'CoalLog' format. The 'CoalLog' Standard improves the efficiency of collection and transfer of Australian coal exploration data and provides a basis for easier data analysis and training.
