Newsletter May 2018

It is wonderful to see that coal exploration industry back in full swing. During the downturn, we at GeoCheck have been taking advantage of this quiet period developing further tools to assist our customers in handling their data. We thought it was about time to let you all know about these.

Generating Hole Summaries with LogCheck

It constantly disturbs us to see clients spending their time on routine tasks that their computer could be doing for them if only there were facilities to do it. One of these is the generation of Hole Summaries. These are one or two page summaries for each hole including location information, depths of different types of drilling, seams and horizons encountered, casing, Las data received and rehabilitation performed.

These are produced on nearly every coal exploration project and are generally created by the geologist cutting and pasting data from the computer into a spreadsheet. With release seven of LogCheck, the geologist can now generate these summaries automatically from the data held in LogCheck. For further information about LogCheck’s hole summaries and how to create them click here.

Displaying Geologist’s Initials and Bit Type with CoalLog Geology Data

Before CoalLog, a number of Geology data formats included columns for Geologist’s Initials and/or Bit Type on every record. As both of these items stayed the same over multiple Geology records and were not really Geology data but rather metadata, CoalLog stores this information in different tables to the Geology data. However when examining Geology data, the related Geologist and Bit Type for each record may be quite useful information.

LogCheck users with release 7.101 or later who record their data in CoalLog format, can now display on each Geology record the related Geologist’s initials derived from their Geologists data and/or the Bit Type derived from their Drilling data. These fields are read only when displayed in the Geology data and still need to be edited in the Geologists and Drilling data if need be. For further information on how to display this information with the Geology click here.

Conversion of Historical Geological Data into CoalLog Format

CoalLog logo CoalLog — The Borehole Data Standard for the Australian Coal Industry has been widely adopted within the industry for on-going drilling. The problem though for many is that they have previously collected data on their lease that is not in CoalLog format and so cannot easily combine with their current drilling data. We have developed a series of tools that we can use to efficiently convert historical data into CoalLog format. For further information click here.

Auditing, Cleaning, Filtering and Merging Las File Data

Every coal company seems to have a multitude of Las files with varying conventions for: the metadata stored in the Las file header, the naming of variables, how variables are spread across files and even the filtering that variables have had applied to them. We have developed a new tool called LasManager that you can purchase to assist in finding what Las data you have and to clean it up.

Alternatively, we are now offering the service of using LasManager and other tools to determine what Las data you have and then cleaning it up so that you end up with a single Las file for each hole with clean and appropriately named and filtered variables. If you only have hard copy of your geophysics for some older holes we can even digitize this and return it to you as a Las file.

Determining Resource Estimates and their Maximum Level of Uncertainty

The latest release of the Australian Guidelines for the Estimation and Classification of Coal Resources expects the Competent Person not only to classify a resource into Measured, Indicated and Inferred but also to provide an estimate of the maximum level of uncertainty in these resource estimates. This can be done using the geostatistical method known as conditional simulation. We have undertaken a number of such studies and can do one for you. For more information click here.

Geostatistical resource estimates

Assisting with Project Evaluation, Resource Estimation, Database Development, Coal Quality and Geotechnical Assessment, Exploration Planning and Execution

The GeoCheck consulting team has many years’s experience in all these areas and have completed numerous JORC and NI43-101 Canadian reports for various clients in Australia and overseas coal provinces. They bring a depth of experience from working with global mine operators before joining the GeoCheck team. For more information click here.

Price Changes

Having not changed our prices since 2013, we decided that now the industry is up and running again it was time to adjust our prices to cover the inflation that has occurred since 2013. For more information click here.
