Plot types available:

• Logs:
  • Tadpole dip plot of true, residual, structural, or averaged dips.
  • True dips and residual dips together on a single log
  • Structural dips (interpreted structural tilt)
  • Dip points
  • Projection types:
    • Stereographic
    • Linear
    • Orthographic
  • Azimuth points (dip azimuth)
  • Strike azimuth points with the option to color the direction of maximum principle stress
  • Modeling Logs--Log data from correlation log, template log, or modeled template log plotted with a map section (described below)  These logs may be either vertical or horizontal depending on borehole orientation.
• Log overplots:
  • Deviation
  • Correlation log
  • Tops
  • Rose plots -- evenly-spaced or irregular intervals
  • Log Header
• Apparent-Dip Sections--(also known as stick, bottle-brush, or herringbone plots) in depth or seismic time
  • Angle Sections--Cross section is defined by the azimuth of the cross section
  • Map Sections--Cross section is defined by points on a map.
• Rose plots -- evenly-spaced or irregular intervals
• Log Header
• SCAT plots ( Bengston, C. A., 1981)
• Polar plots with several projection types:
  • Equal Angle (Stereographic or Wulff)
  • Equal Area (Schmidt)
  • Modified Stereographic
  • Orthographic
  • Linear
  • Tangent.  This projection can be used to determine fold axes -- in a fashion similar to the fold axis plots and pi diagrams described below.
• Polar plots can be of of either dips or poles to dip
• Polar Plot Overlays--Only available when plotting poles to dip (not dip).
  • Pole Frequency Contours
  • Shadow Zone Contours
• Poles to dip on polar plots may be plotted in either upper or lower hemisphere
• Equatorial Nets of all of the polar projections
• Fold Axis plots.  These plots are useful in determining fold axes as well as the for determining the mapping-strike of fault cuts (from drag folds).  See fold axis topic.
• Pi diagrams.  Similar to fold axis plots above.
• Dip azimuth vector plots
• Directional rose diagrams (using dip azimuth) with optional vector mean arrows.  Can use true dips or residual dips
• Bidirectional rose diagrams for linear features (using strike azimuth).  Can use azimuths from true dips or residual dips
• Synthetic deviation (SYNDEV) plots (Berg, C.R., 1998).  This collection of plots integrates the best features of cumulative dip plots and dip azimuth vector plots.  SYNDEV also includes several other interpretive plots.
• Multiwell plots include stick plots in both depth and seismic time as well as maps showing borehole directory and cross section locations.

• Cross sections for tracking stratigraphy with structure in vertical as well as horizontal wells

• TST section using averaged true dips for TST calculations

• Smoothed TST section using structural dips for TST calculations

• Displacement sections for horizontal wells can display a vertically projected section to approximate structure

• Multi-curve Logs -- Customizable wireline logs with dip-associated panels.  Can display data with non-uniform sampling such as core data with symbols or lines or both.  Colors and line styles are customizable.  Can add non-standard curves and panels.

• "Triple combo" with dips

• SCAT

• SCAT with transverse apparent dip section, always displayed in true vertical depth

• Fracture Frequency and Density Curves can be plotted on Multi-Curve Logs

• True stratigraphic thickness (TST) and true vertical thickness (TVT) logs

• When the borehole is traveling up section, the correlation log is plotted in a different color

• When a section repeats, the user can define, in measured depth, which data will be viewed in TST or TVT logs.  This way downgoing and upgoing logs can be viewed side by side.

• Example (data Courtesy Burlington Resources Canada Ltd.)  This well has a couple of places where it travels up section.  Near the bottom of the well, it curls through a fold hinge, first going down section and then traveling up section to the objective.  The links below are to Word Documents in which EMF files output from RDA have been inserted.

• Cross section with dips (stick plot) with measured depth tick marks

• Cross section with dips with TST tick marks

• Original log in measured depth

• Separated downgoing and upgoing TST legs.  Downgoing gamma trace is in black while upgoing gamma trace is in red.
