Our impact on the Geothermal industry

We offer a product suite with modelling capabilities for many industries, including Leapfrog Geothermal for the geothermal energy sector.

Geothermal energy is heat from the earth

Geothermal energy is now being harnessed by regions world-wide as an affordable, clean, and sustainable energy source. The interactive map below shows the geothermal 2017 electrical generating capacities per country:

Optimum performance with Leapfrog projects

By Tim Schurr

Have you noticed the “.aproj_data” folder that always appears along-side your Leapfrog project file?

If you’ve ever had to move or copy a project to another location, you’ve probably come across it, opened folder using explorer and discovered a whole raft of sub-folders and files and thought “What’s all of this?  Is this really my Leapfrog project?”

In this article, I will explain the reason why Leapfrog saves projects in seemingly such a bizarre way, then I’ll give you a couple of tricks on how to get the best performance and reliability out of your Leapfrog projects.

Predictions at locations where there are no measurements

By Richard Lane

A key feature problem in geological modelling is how to take scattered measurements and use these to make predictions at locations where there are no measurements. The data may be measurements on the surface, or samples taken from drilling, or channel samples taken while excavating. Figure 1 shows the basic problem. Solving this problem is fundamental to how Leapfrog software works, and it underpins the geological and mineralization models that are produced.

Interpolation and anisotropy

By Kirk Spragg

Introduction

In addition to interpolation, Leapfrog provides two tools that give the user control over the continuity of grade in their interpolants. These are the “Global Trend” and the more advanced “Structural Trend”.

The Global Trend can be effectively used to alter the results of an interpolant.  The Global Trend  is suitable to use in situations where the underlying geology implies that grade is continuous in a planar direction over large distances. If this is not the case, and the underlying geology implies that direction of grade continuity varies over space, then Leapfrog’s Structural Trend is a more appropriate tool to use when modelling your deposit or ore body.

Is expensive video hardware for Leapfrog worth the cost?

By Kirk Spragg

The retail cost of video hardware is not a reliable guide to how well Leapfrog’s 3D visualisation functionality performs on that hardware. The more expensive workstation grade hardware solutions such as NVIDIA’s Quadro range of desktop cards are designed to accelerate operations that Leapfrog does not use. As a result, the 3D performance in Leapfrog is often no better than less expensive gaming and home grade video hardware.

In this post Applications Specialist Kirk Spragg compares five home and gaming grade video cards with a workstation grade Quadro 4000 by benchmarking the cards to determine their relative performance.

Leapfrog interpolation basics

By Kirk Spragg

Introduction

The Leapfrog software suite uses a mathematical method called interpolation to produce dynamic implicit models.  An interpolation tool, FastRBF™ has been specifically developed by ARANZ Geo. FastRBF™ has revolutionised the way geologists produce geological models, as it dramatically speeds up the process and allows models to be updated dynamically. Although the mathematical details of how FastRBF™ works are somewhat complicated, the basic idea is relatively simple. This blog explains the process using simple examples.

Interpolation is a method that produces an estimate or “interpolated value” of a quantity which is not known at a point X say but is known at other points such as from drillhole data.  With the user’s expert guidance, Leapfrog uses FastRBF™ to “interpolate” or fill in the gaps where there is no data.  This is how Leapfrog creates deposits, intrusions and grade shells from the user’s data. Since FastRBF™ is fast, results can be quickly updated when new data is added, ensuring the implicit model is dynamic.
