Graphs

The Graphs section in the Views bar provides tools for visualizing and analyzing relationships within your data. It includes the following graph types:

  1. Cross-Plot: Visualize the relationship between two selected attributes plotted on the X and Y axes. This is particularly useful for identifying trends, correlations, and patterns in the data.
  2. Histogram: Display the frequency distribution of well log data. Use histograms to analyze data ranges, identify dominant values, and detect outliers in well attributes.
  3. Variogram: Visualizes spatial continuity by plotting semivariance against lag distance, aiding geostatistical analysis.
  4. Stereonet: Plot structural orientations, such as dip and azimuth, on a stereographic projection. Stereonets are especially valuable for analyzing geological structures, such as faults, bedding planes, and stress orientations.
  5. Mohr diagram: Plot the fracture planes of a well core table against a single stress state, which shows which of the planes are critically stressed.
  6. Wellbore stability: Compare predicted stability across drilling directions with well trajectories and observed breakouts.
  7. Pine graph: A quality-control tool for velocity models that plots the depth difference between well markers and the velocity-derived depth.
  8. Tornado: Show how much the result of a formula changes when each of its input parameters varies between a minimum and a maximum value, which identifies the parameters that influence the result most.
  9. Line chart: Draw the columns of a project table as curves, with one column giving the horizontal values and every other numeric column drawn as a curve of its own.
  10. Focal mechanism: Display the beachball and event details from a calculated Focal Mechanisms dataset.

Focal mechanism

Open Views > Graphs > Focal mechanism. In the Statistical analysis bar, choose a calculated Focal Mechanisms dataset in Dataset, then select an Event ID. For calculation and saving instructions, see Focal Mechanism.

The graph shows the selected event's beachball. Its details report both nodal planes as strike, dip and rake; the azimuth and plunge of the P, T and B axes; the mechanism class; and available source metadata. Neither nodal plane can be identified as the fault from the beachball alone.

The projection (equal-area or equal-angle) and hemisphere (lower or upper) follow the saved dataset and are reported with the event details.
