The latest iteration of the version 17 series of releases, Petrosys 17.6, introduces a wide range of features with a focus on working with and managing spatial data, analysing information from first and third party data sources and improvements to third party interoperability.

The most significant change in 17.6 offers an all new way of working with spatial and GIS data. The Spatial Editor offers a robust and powerful tool with a wide range of applications, building on the functionality previously offered by the Contours, Faults and Polygons editor. Functionality introduced by the editor includes the generation of buffer zones around geological structures and wells, the expression of directional bias or anisotropy over a pre-defined region using lines or polygons; and the sub-division of polygons, allowing for more detailed volumetric analysis alongside traditional editing functions such as drawing, deleting and moving spatial objects. The editor can be used in conjunction with a wide range of data sources – including Excel, dbMap culture groups and Arc GIS – and employs a simple layer based interface which allows for fast, direct access to a powerful range of tools and operations.

Spatial data management has also seen a number of improvements. A finer degree of control may now be exercised over data transferred between third party data sources using the Spatial Data Translator. Data extracted from an input data source may now be filtered, allowing information to be selectively transferred or updated as required. Attribute data may also be re-defined in the output data source, allowing values from the input data source to be explicitly mapped to new or existing attributes in the output data source. Support for third party spatial data formats (including IHS Kingdom ASCII culture/polygon data and Excel) has also been expanded, broadening the application of the tool across a range of industry standard formats.

Contours have also received a number of updates in 17.6. The appearance of contour annotations – particularly in regions with steep gradients – has been improved significantly to reduce instances of overlapping or badly drawn labels. Contour annotations may now also be modified directly using interactive overpost corrections, allowing for far greater control over the final layout of a map in the event that things aren’t lining up just right.

contour_labels

Contour label placement has been improved significantly in 17.6. Contours are now also supported by the Overpost Correction feature in Mapping, which enables the interactive alignment of labels (demonstrated above) alongside a range of pre-existing features.

Improvements have also been made both in the creation and visualisation of grids. Surface Modeling is now capable of gridding depth, time and velocities from well checkshot data. Each new data type is offered as an input data source for all supported gridding methods. The visualisation of grids in Mapping has also been considerably improved. In particular, performance improvements have been made when working with large grids. In some cases, grids which once took minutes to display are now loaded almost instantaneously. Sun-shaded grid visualisation has also undergone numerous changes, facilitating a far cleaner and noise free visualisation than in previous versions.

noise_reduction

Noise in sun-shaded grid visualisations has been reduced significantly, producing a cleaner and more accurate representation of the underlying grid data.

Database lists, previously used for viewing and editing data stored in Petrosys dbMap databases, have been modified to allow support for DUG Insight, IHS Petra, Paradigm-Epos, Petrel and SeisWare. Lists can be populated using queries, forms or geographical regions. Selection files from Petra (WSN) and Paradigm are also supported.

17.6 also introduces a significant new tool for data analysis – Cross Plotting – which allows any two values from a list to be plotted graphically. Cross Plots may also be used to establish the linear relationship between the two plotted variables, along with the relevant correlation coefficient. The resulting plot may be exported in a range of image formats or a PDF for inclusion in reports or other documentation.

cross_plottinh

Cross plots can be used to analyse continuous data directly from a list. Plots can be output to a range of image formats, or to PDF.

Third party interoperability has seen further improvements, with improved support added to most applications. Petrel is now supported by the Wells Import Wizard, Fault Stick and 3D Seismic Surface Exchange. In addition, Petrel gradient files (in the .alut format) may now be imported into the Gradient Editor. IHS Kingdom grids may now be displayed directly in Mapping, or contoured using the Surface Modeling application. IHS Kingdom ASCII culture and polygon files are also now supported in both Mapping, as GIS layers, and as input and out犀利士
