Top 5 Inversion Best Practices: Web Series
What are some of the most common, impactful things you can do to improve your 3D geophysical inversion models? Geosoft’s Taronish Pithawala, technical lead for geophysical modelling, presents the ‘Top 5 Inversion Best Practices’ in a web series that starts this week.
The web series will build on the best practices workshop hosted in March with Dr. Rob Ellis, Geosoft's senior scientist for earth modelling. The videos will cover tips on choosing auxiliary information, inverting large datasets, interpreting magnetization vector inversion results, using constraints, and preparing gravity gradiometer data for inversion.
The first two videos in the series are now available online. More videos will be added, and announced, over the coming month.
This introductory video covers some of the fundamental ideas and equations behind inversion theory as applied to VOXI Earth Modelling. Inversion fundamentals include optimizing the objective function, data misfit, and model norms.
In this episode, learn why auxiliary parameters are the most important, and often most overlooked inputs to inversion modelling. See how to determine the best cell size; understand why we recommend optimum data sampling; learn when to use absolute and relative errors; and find out how trend removal can dramatically improve your inversion results.
