Modern geoscientific data, from exploration through to production, is sourced from an extremely broad range of sensing technologies that generate data of varying size and intrinsic information content. Data may comprise all levels of measurement, from nominal (rock type), ordinal (degree of alteration), interval (azimuth) and ratio (concentration) scales. Additionally, the data may be incomplete, vary in measurement precision with time and location, contain artefacts (closure) and be collected at vastly different spatial scales; from continental surveys to discrete meter(s) long sample increments, to continuous downhole logs.
Analytics in Geoscience also needs to adapt to some peculiar requirements. Our data is typically not ‘large’ but is often incomplete. Analytics in exploration models out background to find the outliers; the ‘sensors’ need to be moved to the (remote) point of data collection and the analytics done at the ‘edge’ environment, not months later. Conversely, production seeks to eliminate outliers to better model background and also needs to link spatial and temporal data. The historical emphasis of Analytics in Geoscience has been on exploratory data analysis. To move to machine learning requires high quality nominal data for training which is typically unavailable or determined by imperfect ‘human’ sensors.
These are issues, but there are also immense opportunities for the industry should the Data Scientists of the future be carefully guided by the Geoscientists once the novelty of the approach has worn off.
Dave Lawie
Dave holds the dual roles of Chief Geoscientist and Chief Technologist – Mining for IMDEX. Prior to joining Imdex, Dave held global positions in exploration geochemistry and R&D with Pasminco and Anglo American before co-founding ioGlobal in 2004 as Managing Director.
Dave grew ioGlobal into a global company specialising in geochemistry and geometallurgical consulting services, cloud-based data management and the ioGAS desktop analytics software – the company was acquired by IMDEX in 2012.
Dave has a PhD in Geosciences and Analytics from the University of New England and a trade qualification as an Instrument Technician.
Putra Sadikin
Putra is a Melbourne-based geoscientist with 10+ years of experience in various roles in the mining industry, from geochemistry consulting, exploration geology, and geoscience software R+D and product support. Putra graduated from the University of Melbourne in 2011 with a M.Sc degree in Geochemistry, and thereafter joined ioGlobal as a Geochemist before continuing his career at IMDEX.
He has a strong interest in seeking and introducing new technology and concepts to the mining industry and in championing these ideas to those within and outside of the industry. Putra works on the ioGAS product management team as the bridge between its customers and the product development team.
Daniel Muggleton
Daniel Muggleton is an Australian stand-up comedian based in Sydney. His debut special ‘Let’s Never Hang Out’ aired on ABC Comedy in 2019 he’s also appeared on The Feed (SBS) and The Checkout.
