ARGUS Features

Features

Advanced Fault Network Management

A complete 3D vector field is interpolated from orientation and trace data for each fault. The fault’s surface is extracted using a marching cube method which is clipped if necessary. The fault’s vector field is also used as the basis for a drift function, which is applied to the relevant lithological interfaces. This process enables data-driven modelling as the throws are being calculated, not assumed.

Drillhole Management

ARGUS supports the standard Collar, Survey, Geology format for both import and export of lithological, numerical and structural data. Geochemical assays may be used as an input for point cloud meshes to interpolate grade shells using ARGUS’  resource estimation toolkit. Drillhole data cross validates dynamically against the computed implicit 3D geological model to highlight inconsistencies and guide daily improvement of your understanding of the geology. The geological information is honoured through coKriging inequality constraints.

Conceptualization for Groundwater modelling

ARGUS proposes a fully integrated and customizable meshing tool using CGAL technology. The conceptualization may then be loaded directly into FEFLOW without any conversion step. Tetrahedron meshes are guaranteed watertight and manifold for arbitrary geological shapes. Special mesh validation and mesh refining tools are also provided to ensure the best outcome for finite elements simulation.

Geological Implicit Modelling

ARGUS uses a geostatistical vector field interpolator to build the 3D interfaces and fault network using structural data, sections, drillholes and geophysics as inputs. The CoKriging interpolator allows the user to define formation-specific anisotropy settings to better represent geological structures even with sparse and scarce data. Model topology is set via the stratigraphic pile which enables the transfer of external geological knowledge into the modelling with minimal setup. Advanced fault network management enables realistic structurally complex modelling.

Geothermal Modelling

ARGUS provides an enhanced Geothermal Modelling tool kit and rapid calculation of 3D temperature, heat flow and geothermal gradients directly from a 3D geology model which can easily be examined, refined with boundary conditions and recomputed. The solver in ARGUS accounts for heat transfer processes of conduction, heat production and advection and solves for steady state 3D temperature while accounting for spatially variable thermal conductivity.

 

Seismic Toolbox

ARGUS provides a comprehensive tool kit aimed at integrating seismic and microseismic data into 3D geological and geostatistical modelling. A recent improvement to ARGUS provides a very efficient method for simplifying seismic derived interpolated surfaces which may be made up of many thousands of points….
