All projects have their challenges, but those with a fast turnaround have a special set of problems and pressures.

A succession of accelerated construction deadlines may call for rapid iteration of geological models to meet the shrinking timelines. You might need to develop multiple hypotheses from the data you have, often in a very short space of time.

That would be ok if the software you were using was built from the ground-up specifically with geologic modelling in mind, but often it isn’t. Instead, you may be relying on tools co-opted from another industry or discipline and not intended for the ‘artform’ of geological modelling. Not only will that tend to make the initial modeling process slow and difficult, but when new data comes in – as it frequently will – it could take days, even weeks to update the model. Meanwhile, the project is already underway and costing money.

3D model

Leapfrog Works comes to the rescue of time-pressured geologists like myself. I have been impressed with this software specifically catering to the needs of ground engineering as it honours data from multiple sources, while allowing the flexibility to add interpretation and form a model into a realistic representation.

For example, on a project you could quickly generate multiple models to test different scenarios. Is there a fault here? What happens if you tweak the design here to suit the geology? With Leapfrog you can do all that in less time than it would take to explicitly build one rough first-pass model.

Importantly, it’s also based on a data hierarchy, which means that as new data is added or updated, the entire model downstream will adjust to account for the changes. That’s a huge advantage over having to manually update every entity within the system.

How Leapfrog does it

  • Implicit Modelling reduces the time to get to a first pass product by effectively “connecting the dots” from input data. This brings the days or weeks required to hand-digitise polygons for a first pass model down to – literally – seconds.
  • Once the initial surface or volume is generated, it is up to the geologist to sculpt and form that shape into something that is geologically reasonable while still honouring all of the input data. With Leapfrog this is typically done in full 3D space rather than in cross-sectional view. This allows the entire model to be considered at once rather than small portions within the cross-section.
  • Multiple modelling approaches or hypotheses can be considered by simply making multiple surfaces to represent the same geologic unit. These surfaces can be compared with one another and with the overall system, and the best surface will be used for the final volume calculations.
