Tools for exploration success

Maptek Eureka™ brings a practical focus to the dilemma of analysis of information when there is too much data rather than not enough.

Exploration has moved a long way from prospectors stumbling across outcrops. Most of the new discoveries have no surface expression. Fortunately, we have many other sources of information.

Google Earth lets us explore the whole earth without leaving our desks, via satellite imagery, maps and terrain data.

Vast areas have been surveyed by airborne and ground geophysical methods. Deep well logs from petroleum exploration are easily accessible. Old drillhole locations can be found with GPS. Historic plans can be scanned. A huge amount of exploration can be done before venturing into the field. Or can it?

In many cases, there is simply too much data to juggle. It can’t fit on a desk, let alone a laptop. The task of fitting all the pieces of the puzzle together can be overwhelming. Until now!

Maptek Eureka™ provides a single 3D environment for accessing and managing all geospatial and geophysical information, with specialist tools for correlating drilling and seismic data.

Eureka supports all common CAD and geometry files, triangulated surfaces, .csv and ascii text files, image files (including .ecw and geotiff) and seismic SEGY formats, as well as terrestrial and airborne laser scan and photogrammetry data formats. Connection to Vulcan allows direct access to geology and drilling databases.

Typically, the problem of too much data is handled by filtering it down to a manageable size. The end-user does not get to see the original raw data. The task then is to analyse the results from different datasets and drill interesting anomalies.

Modelling software like Maptek Vulcan™ has made it easy to overlay and match these different data types, to draw lines and make correlations. The geologist’s task became easier, but intuition said that there was information missing.

With Eureka, ALL the raw data can be used. All at once. All over the place. Once you’ve set up and stored the data for your project, there is no need to worry about dataset size outrunning your processing capability.

Eureka works like your brain. It uses all the information that you need for looking at a particular level of detail.

As you zoom closer, Eureka allows you to see greater detail. Points, drillholes and objects can be easily viewed, rotated and manipulated. Section views, transparency options, tied-windows and other techniques allow you to look at more data at once, and to make instant connections.

Being able to see corresponding trends, features and anomalies in the various datasets enhances understanding of the geology. This increases the confidence an individual or company can have in exploration findings.

The Eureka tablet equips the field geologist to interact with office colleagues. Interactive location maps, streamlined logging via handwriting recognition, virtual keyboard and dropdown lists for data entry enhance field work.

Instant communication means that no time is wasted when critical decisions must be made about an exploration program.
