On 13th February 2025, Mark Bentley (Langdale Geoscience, UK) delivered a short course to the WA Pesa Branch members on “Good Models: Bad Models – How can we Tell?”. This course was well attended and a summary of this course is provided below.
Mark also delivered a presentation to the WA Pesa Brach on “Modelling for CCS – new tricks for old dogs”. Thirty or so young and ‘old dogs’ enjoyed an engaging, educational and stimulating evening with Mark who presented on the new paradigms required in reservoir modelling for CO2 storage. The presentation covered the changes in scale and multi scale problems for CO2 storage modelling, sideburns and geomechanics, super-critical fluids (the 4th phase), surface tension of CO2, capillary effects and hysteresis, the importance and impact of heterogeneity, and the scale offered by regional aquifers rather than depleted fields. It was also highly interactive evening with many questions and discussions as we went along. While many of the tools are familiar to us, the concepts introduced were mind opening, a highly educational evening was enjoyed by all. (summary by Matt Fittall).
