Although most of the plots within these windows are available for
plotting in the plot window, they are set up such that the
user can analyze the plots with scales and plotting parameters designed for screen
viewing. (Parameters best for plotting to paper will frequently have symbol sizes
and annotation to small to read on-screen, or they may make the plot too large to view all
of the dips at one time.) In addition, most of the windows have visual tools to aid
- The analysis windows include:
Index Window--A dip log and a polar plot display the toggled index
color. In addition, the dip type visibility and the active fracture
set can be set here.
Polar Analysis Window --Instantly see the where dips on a log are
displayed on a polar plot and vice versa.
SCAT Window-- In this window, the 5
are arranged on screen to interactively analyze the changes in domain azimuths.
Multiple domains can be viewed at once or the screen can toggle to just one
domain. Transverse and longitudinal directions may be calculated by
two statistical techniques or simply input by the user.
Window -- A polar plot
and dip log are arranged such that a dip range selected on the dip log can be
statistically analyzed for the
axis. In other words, the user defines
the drag-fold interval to enter into the statistical calculations. The user may also
pick the drag fold visually by picking two points on the polar plot to define the great
circle of the best-fit plane.
Vector Section Window -- Displays Vector Sections along with modeling
logs for geosteering.
SYNDEV Window -- In this window, 6 SYNDEV plots
can be viewed at scales amenable for screen viewing.
View Residuals Window -- This simple window consists of four plots, true and residual
dips plotted on both dip logs and polar plots. It is convenient for getting a quick
look at the dips and residual dips side by side.
- Utility Windows
Edit Window -- Dips can be deleted based on quality, or
maximum search angle, or they can be selected visually. Dips can also be
hidden, overturned, or hidden.
- Merge Window -- New dips can be added visually to the current
true dips and the qualities may be multiplied to match. Coloring by
quality aids in the selection of the best quality multiplier.
- Export Window -- Merges and averages input dips and
interpolates deviations on all data points for export into programs
requiring 3-D coordinates. Deviations are interpolated by minimum
curvature instead of linear interpolation to create smooth boreholes.
Whole-Well Average Window --
Averaged dips are viewed alongside the original dips. The dips
can be smoothed in a running average or decimated by replacing each set of
averaged dips with a single dip. The averaged data can then be saved
to file and then used as the true dips.
- Windows for entering
Pick Structural Window -- in this window the structural dips are picked by
clicking on a dip versus depth plot for the dip and by clicking on a azimuth versus depth
plot for the azimuth. Alternatively, dip and azimuth can be input
Structural Window -- the dips are picked by clicking on individual
dips or by dragging across groups of dips for averaging.
Depth-Range Average Window -- This window is set up to view an
average on a
screen similar to the "Pick structural" window. The user
drags through a depth range to average and then can view the
relationships between the averaged dip and the dips that go into the average before adding
the averaged dip to the structural dips.
- Multiwell module
- Multiwell Section Window
Map View --
Features "point and click" picking of cross sections or the option to put in
exact end-point coordinates.
-- View user-defined cross section locations on single wells as well as
multiple wells. Has the same prognosis and Stratigraphic Section tools
that are available in the Horizontal Well Tracking window above (under
- Print maps and cross sections directly from the map
and section views above
- Automatically merge and average single-well data in a
- Can color by formation as well as the standard
azimuth, depth, quality and dip-type criteria.
