Vulcan 9.1 models ALL of your data

New stratigraphic modelling tools in Maptek Vulcan 9.1 ensure geologists and engineers make the most of their valuable data.

Stratigraphic modelling has come a long way since the days when each site had a ‘handcrafted’ macro – virtually held under lock and key,  only to be released once a year to rerun the resource model.

The revolution in stratigraphic modelling began with the release of Vulcan™ 6. The Integrated Stratigraphic Modelling (ISM) workflow brought the tools for making accurate and timely geological models onto the desktops of all users.

However, just because the ISM workflow made it simpler to incorporate all the available geological and exploration data into the final model, it didn’t mean all sites immediately embraced it.

Protocol must be clearly followed, especially at larger operations, before such a comprehensive change in approach can be adopted. Acceptance timeframes are not uncommonly measured in years.

Adoption of the ISM tools reached a peak during the Vulcan 9.1 development period. Guided by client feedback and requests, we have responded to many additional requests within this version. Vulcan 9.1 ensures that nothing is lost.

In short, users want to squeeze the most value out of all their data, especially in tougher economic conditions when it becomes a clear case of ‘use it or lose it’.

Use all your data

If you happen to have a ‘spare’ 40,000 correlated blastholes, which in the past could not be used effectively in FixDHD due to containing only one horizon, then try the new short hole capability.

This allows you to really tie down your structural models with high resolution drillhole data – without introducing any artefacts in the remainder of the stratigraphic sequence due to over-enthusiastic interpolation. As an added bonus it will probably run 20 times faster!

Perhaps when your drillholes start or end in the coal seam, you are tired of telling Vulcan that this really is the roof or floor of the coal!

If so, try the new trust list option in FixDHD. Instead of ignoring these holes or fudging additional intervals in your database, simply specify which holes you trust for the roof or floor and let FixDHD do the rest. Your valuable data will be honoured – without compromising the original drilling data.

Model stratigraphy

Are you frustrated at having to discard lots of valuable in-pit, crop line, scanned or seismic interpretations because you prefer to use a stacking base method in Model Stratigraphy?

In Vulcan 9.1 there is no need to throw away data – simply select the new hybrid base method and include everything in the additional design data section for any or all horizons. ISM will let you have your (layer) cake and eat it too!

If you prefer the structural surfaces approach, the new preserve thickness option will help prevent unrealistic pinch-outs or thickening of seams. This uses thickness information from the structural surface with the most information to control the surface with the least.

These two apparently small changes will have a profound influence on modelling stratigraphic deposits. Even more power is placed in the hands of geologists or engineers, ensuring that no relevant data is left unused.

HARP models

HARP modellers are not ignored. Enhancements to HARP creation mean that you can include modelled or constant values directly in the waste blocks between horizons as well as within horizons, with the option to break them down into vertical sub-blocks.

If you already have a perfected HARP model and want to upgrade it with additional information from grids or constants, then try the new update HARP model qualities option. You will save time and effort by not having to recreate your model from first principles.

Model sharing

Once you have created a terrific HARP model and are satisfied that you have squeezed the most value out of your hard won data, you will be keen to share it. The new export HARP model to surfaces option has that covered too.

As the name suggests this option allows you to easily extract any structural or quality data from the model directly to triangulations or grids ready for downstream use. There is no need to copy thousands of grid and triangulation files in order to share your model.

You spend a lot of time and money collecting data. Maptek ensures that you get the most value out of it. Vulcan 9.1 goes a long way to helping you work in the most  efficient way to meet your goals.
