Isatis 2013 boosts data exchange with acQuire
Isatis offers a direct link with acQuire. This link allows the transfer of a drill hole dataset from the acQuire database into Isatis for analysis, making laborious import/export routines redundant. The link is fast, easy to use, and fully integrated within Isatis. Geovariances says “this new interface with acQuire database will position Isatis at the core of your software portfolio.” To define the selection criteria for your extraction you can use an existing acQuire Selection File (*.sel) or create a new one. “This new import interface,” Geovariances says, “makes data selection and transfer faster, more powerful and guarantees the integrity of the information on which your analysis is based.”The latest Isatis release facilitates software usage by offering integrated workflows guiding the user directly to the expected results. It also offers innovation with Multi Acquisition Automatic Factorial Kriging (MAAFK) workflow, a new application for 4D seismic data filtering.Isatis 2013 eases software usage, helping to master the software through workflows. Several workflows providing guidelines for specific geostatistical processing have been made available in the software. They allow you to go through the different menus quickly to the results.These workflows are stored as Isatis journal files. They let you specify your own parameters while driving you to the next step.Four workflows are ready for kriging, uniform conditioning, turning bands and plurigaussian simulations. Additional workflows are to be developed for mining resource estimation issues (non stationary kriging, direct block simulations, localized uniform conditioning).Isatis 2013 still innovates, improving seismic data value. Isatis now offers exclusive MAAFK, which provides a quick and easy way to extract the common part of two redundant measurements of the same quantity using geostatistical filtering. The application implements the exclusive-to-Isatis automatic variogram fitting algorithm and automatic factorial cokriging. MAAFK is of particular interest for time-lapse seismic processing or dataset merging.In order to be more in line with Datamine StudioTM, GSLIB and VulcanTM, new rotation systems have been added to Isatis. Rotations can now be copied from experimental variograms to models, or from models to neighbourhoods, through a simple click.Axes unit can now be set to meter, feet or millisecond depending on your data.Isatis 2013 improves resource estimation, enhancing orebody knowledge. Grade Simulation Post-processing, used to compute grade tonnage curves from block simulations computed on Selective Mining Units or on panel grids, has been renamed Grade Reblocking. You may now compute grade curves from one kriged grade variable or from a set of simulation realisations.Contact Analysis is used to check the grade behaviour at the contact between two domains. The application has been improved so that it now lets you define a weight variable, to give less weight to small samples.Border Effect checks relationships between domains and grades by computing transition probabilities from one domain to another one. By normalising the probabilities, the application makes it easier to see what happens at the domain borders.Isatis 2013 improves performancesIn EDA when displaying huge variogram cloudsIn Automatic Variogram FittingIn Turning Bands Simulations when the amount of grid nodes to be simulated is small in comparison to the total size of the block modelIn Grid Filling which lets you define sub-grids in order to speed up calculations and optimize memory allocationIn Selection from Polygons.Isatis 2013 delivers new statistics. Variogram cloud dispersion is sometimes tricky to assess when computed on huge datasets. Isatis EDA now offers two additional ways of displaying variogram clouds, either using box plots or raster display.Copy Statistics now stores the sum of all the values of a variableTo predict a variable from several explanatory variables, Multi-linear Regression is now able to automatically select the variables which have the highest signification. The Stepwise Algorithm is used to test various combinations. Isatis lets you store the computed regression function in a parameters fileParameter Files and Model Definition now let you display defined variogram models and variogram maps.Isatis 2013 improves modelFlumy, the reservoir model for meandering channelised systems, can now load deviated wells. It also lets you enter the erodability information as 3D grids and choose the flow direction of the channelsSequential Gaussian Simulations lets you perform a Collocated Cokriging during the conditioning stage.
