Cross-plot analysis is allowing users to compare two variables on a scatter plot to identify relationships, trends, or anomalies.
To create cross plot view go to the Views bar, navigate to Graphs and click on Cross plot button:
To set what data to be analyzed set parameters in the Statistical analysis bar:
Cross-plot analysis is helpful to the user to understand the relation between two or more seismic attributes. In this cross-plot analysis bar the user can able to select the seismic attributes and generate the cross plot in Views
In the Data Source dropdown menu, you can choose the type of data to analyze. Available options include XY Data and Well Logs.
When XY Data is selected as the data source in the Cross-Plot Analysis tool, the interface allows users to analyze relationships between two variables (X and Y coordinates). This mode is particularly useful for investigating well attributes, seismic attributes, or any spatially correlated data that can be expressed in an XY format.
For the Horizontal Group (X-axis) and Vertical Group (Y-axis), you can select a group of well attributes (such as X, Y, KB), markers, topography, grid maps, or horizons as the group for analysis. You can then specify the desired parameter from each group.
The Color option allows you to define a third parameter for analysis, which will be used to color the data points on the cross-plot. This additional dimension provides deeper insight into data distribution or behavior. For example, you could color the data points based on a seismic attribute like amplitude or porosity, adding another layer of interpretation.
The Bounding Polygon option allows you to limit the analysis to specific areas of interest. By defining a polygon, you can filter out data points outside the selected region. If no polygon is required, leave this option set to Not required.
When Well Logs is selected as the data source in the Cross-Plot Analysis tool, the interface enables the analysis of relationships between well log measurements for individual wells. This is especially useful for examining the correlation between different well log parameters (e.g., porosity, resistivity, sonic log) within a specific well.
For the Horizontal Group (X-axis) and Vertical Group (Y-axis), you can select a specific well from the Group dropdown menu and then specify the parameter from the selected well (such as RHOZ, DEPTH, DT, etc.).
The Color option enables you to add a third parameter to your analysis. This third parameter is used to color the data points in the cross-plot, allowing you to visualize how a specific log (such as sonic log DT) varies across the plotted data.
Filter by MD
•Manual: Allows you to manually input the MD values.
•By markers: Uses predefined geological markers to select the interval of the analysis.
In the Cross-plot view, you will find two regression functions: linear and quadratic. These functions help in identifying trends and correlations between the selected parameters. Both regression lines are also accessible through the Vista tab within the View Properties panel, where you can further customize the visual settings, such as line color, thickness, and other aesthetic preferences, to suit your needs.
