CoalLog

CoalLog - The Australian Coal Logging Standard v2.1

The CoalLog standard includes data entry sheets and standard dictionaries of code lookup tables for coal borehole header, drilling, lithology, water flow and geotechnical data, a format for the transferal of this data, a borehole logging training manual and standard plotting patterns for all its defined lithotypes and lithology qualifiers.

Before CoalLog, there were approximately 30 different data formats and over 100 different dictionaries being used for the capture of geological and geotechnical data from boreholes throughout the Australian coal industry. Additionally, each of the major Australian geological software companies used different conventions for the transferal of this data. These different formats, dictionaries and transferal conventions have led to major inefficiencies in the collection, transfer and analysis of coal borehole data. CoalLog has overcome many of these inefficiencies. The Geological Surveys of both New South Wales and Queensland have adopted it and will be requiring any coal exploration data provided as CoalLog data transfer files.

CoalLog has been developed with financial assistance from the Australian Coal Association Research Program (ACARP) by a number of committees with representatives from most major mining, consulting and software companies in the Australian coal industry. It was first released in February 2012 and the current version (v2.1) was released in August 2018.
Further improvement and development to the Standard is planned and feedback is welcome by sending an email to [email protected]. It is anticipated that there will be an update of CoalLog every year or two. To be added to the list of users notified of new releases, please send an email request to [email protected].
