Interpretation of geological drill hole data is slow, inconsistent and unreliable
3D geological models of the sub-surface are used in minerals exploration to identify potential targets and define resources. These models show the predicted geometry and distribution of different rock types in 3D space.
Traditionally, geologists have constructed cross-sections and 3D models from geology logs, which are the result of manually interpreting rock type from drill cores. Manual geology logging is prone to inconsistency, especially when logged by numerous geologists over a substantial period of time.
Companies have responded to this inconsistency by collecting numerical data from drill holes and core. However, the numerical data must still be interpreted, and this is a time consuming and subjective process. It is especially challenging if multiple variables need to be integrated to make best use of the data.
Automating the process of interpreting multivariate numerical data allows rapid and consistent integration and interpretation of data. Automation will save geologists’ time, lower costs and produce more reliable 3D models.
A new web application that automates data integration and interpretation
We have developed a web-based application, called Data Mosaic, to automate the integration and interpretation of numerical drill core data or downhole data, including multi-element geochemical analysis and wire-line logging.
The software helps geologists to domain and classify rock types along the length of a core. The geologist can upload and view their drill hole data, detect lithological boundaries, create multi-scale lithological domains and apply a multivariate classification scheme (including machine learning).
The Data Mosaic method is unique in that it reduces misclassification of rock types and provides a multiscale result, which can satisfy both the “lumper” or “splitter” styles of geological logging.
Finally, the geologist can export a pseudo-log in a spreadsheet format that mimics traditional logging. The pseudo-log can be exported at any scale, to suit the application, whether it be to generate a simplified large-scale regional model or a detailed fine-scale deposit model.
Data Mosaic makes it fast and easy for exploration and mining geologist to process new data and update their 3D models during active drilling.
Faster analysis, with greater repeatability and robustness of results
Data Mosaic speeds up analysis, reducing tasks that would previously take anywhere from a few hours or days, to weeks and months, depending on the complexity and size of the data set.
By applying consistent algorithms and parameters, Data Mosaic provides pseudo geology logs, which are consistent across the entire data set. This ensures reliable correlation of rock types between drill holes for constructing cross-sections and 3D models.
Data mosaic is a game-changer for the future of geological logging, providing fast, reliable results, which allow the geologist to maximise the value of their data.
