Petrosys PRO surface modeling has the unique ability of being able to simultaneously model data from multiple input sources, drawing on a range of vendor applications and data stores. Surface models and maps are enhanced by greater access and run time filtering of data, supporting a geoscientist’s ability to evaluate and conclude their interpretation on time.
- Unique ability to simultaneously model data from multiple sources
- Superior grid engineering with excellent fault handling
- Easy to configure and re-use modeling workflows that support automation
- Volumetrics – simple and accurate
- Clear logical user interface
Superior Grid Engineering
Grids in Petrosys PRO are engineered to handle the wide range of surface modeling challenges in E&P work ranging from the field to the regional scale. Our flexible grid geometry supports very large grids defined in any projected or geographic coordinate reference system. Intelligent interpolation within grid cells allows high resolution output to be generated without the computational overheads of excessively fine grids.
Faults and Discontinuities
Sharp discontinuities in a surface, such as are associated with faults, are honoured during computation and maintained by the inclusion of the fault geometry within the grid file. This distinctive geometric accuracy delivers a more geologically realistic representation of the subsurface.
Powerful Gridding Algorithms
Petrosys PRO provides a broad range of surface modeling algorithms and mathematical operations to help interpret the subsurface. In addition to geometric methods such as minimum curvature and distance weighted averages, an interactive geostatistics approach can be used.
Extensive Range of Operations
Lateral and vertical grid merging techniques allow the geoscientist to develop consistent regional grids and sound structural and stratigraphic sequences. An established flexing procedure provides extensive control over the correction of seismic-derived depth surfaces with well formation picks. Biased gridding enables highlighting of subtle trends such as in attribute variations due to channel deposits.
Standard and Automated Workflows
Standard geoscience process templates can be combined with arithmetic functions to simulate a range of scenarios. User defined task lists combine multiple steps with optional looping to automate routine and complex workflows such as the periodic updating of reservoir maps, computation of volumetrics and grid generation.
Integrate Seismic Velocities
Petrosys PRO helps geoscientists to perform depth conversions with tools that can use stacking velocities, SEGY, well checkshots and velocity depth functions with a range of data sources and formats.
Contours help geoscientists visualise and refine interpretation and are a vital component of reserves maps. Petrosys PRO provides a high standard of contour displays including good matching of fault cuts, optional blanking of contours in areas of steep gradients, overpost correction and orthocontouring. Graphical re-interpretation of contours and faults can be applied to update either an entire grid or a restricted area such as that affected by a recently drilled well.
Gross rock volumes can be easily calculated from top, top and base, or thickness grids with optional user defined scale factors and volume units. Extensive quality assurance procedures ensure consistent and reliable volume estimates.
The ability to save, log and replay tasks enables consistent, accountable, and repeatable volume estimation to be performed across subsurface teams and over time. Within Petrosys PRO all output is accompanied by comprehensive metadata reporting, which includes input sources, processes applied and coordinate reference system information. This supports auditability and best practice management.
Petrosys PRO is simply the most intuitive application for editing contours and spatial objects…
