Cross-sections are used to depict the geology and stratigraphy of the
subsurface. Typically cross-sections intersect several boreholes, and possibly
other cross-sections, that may or may not be along a straight line. The
stratigraphic information from the boreholes and intersecting cross-sections is
combined with other knowledge of the area to generate the cross-section.
WinFence can be used to graphically create detailed, full-color, cross-sections
easily and quickly. The program can be used to interpret and map soil and rock
layers, contamination, fossils, minerals and hydrocarbons.
A wide variety of strata can be used to create cross-sections using WinFence.
Types of strata that can be used include layers, faults, lenses, intrusions, and
alteration zones. Very detailed and complicated stratigraphy can be represented
and easily drawn. Layers can contain multiple segments to represent
unconformities and erosion in highly faulted zones.
In version 2 there is the option to have the
program automatically generate the cross-section. This is done using artificial
intelligence (AI) built-into the program. When determining how to connect the
strata between boreholes, wells, and intersecting cross-sections the program
looks at the similarities in the lithologies, thicknesses, and occurrence of the
strata. This methodology works well with most geologies; except, where the
geology is very complicated or there are faults. In addition, the program’s AI
will not be able to determine alteration zones. However, these zones can be
added and the strata can be edited after the cross-section has been generated.
Also new in version 2 is the ability to display and use deviated boreholes and
wells. The deviated borehole and well data must first be entered in WinLoG.
After the deviation data has been entered the borehole/well will be displayed in
true depth on the cross-sections.
WinFence shares the same database as WinLoG, and can be used to access and plot
the borehole data entered in WinLoG. Several types of borehole data can be
plotted on the cross-sections; including lithologic symbols, sample symbols,
core logs, well diagrams, graphs, and geophysical logs. The actual borehole log
data can be opened and edited in WinLoG by double-clicking on it in WinFence.
The creation and
editing of cross-sections is supported by the following features::
-
Strata in cross-sections can be automatically generated by the programs
built-in intelligence.
-
No limit to the
number of cross-sections in a project.
-
Graphical Information System (GIS) for displaying and picking boreholes and
cross-sections in WinLoG with WinFence. GIS can also display site features
and import AutoCAD files.
-
Path line can be
straight or bent.
-
Intersecting cross-sections can be displayed on a cross-section.
-
Intersecting cross-sections can be used when automatically generating a new
cross-sections.
-
Deviated boreholes can be displayed on a cross-section.
-
Cross-sections can
use data stored in WinLoG database to show lithologies, graphs, geophysical
logs, samples, and well details at borehole locations
-
Cross-sections can
contain a title bar, legend, location map, and scale bar.
-
Multiple water levels can be drawn on the cross-section. The first water
level can be drawn automatically using the water levels stored in WinLoG.
-
Legend and title
bar of the fence diagram can be fully customized.
-
Title bar can
contain any number and type of data.
-
Legend can contain lithologic symbols with standard or custom
lithology descriptions.
-
New Quick strata toolbar makes editing strata much easier and quicker.
-
Strata from WinLoG project are automatically added to the program.
-
Addition of new strata has been made simpler.
-
Cross-section can contain a location map as an inset, showing
the borehole locations and the pathline.
-
Horizontal and vertical scales of the cross-section can be
specified or automatically fitted by the program.
-
Cross-sections can contain an unlimited number of boreholes
and well logs.
-
Cross-sections can contain an unlimited number of layers,
lenses, intrusions, faults, and alteration zones.
-
Strata can contain descriptions that are shown in the legend.
-
Strata boundaries can be connected by straight lines or a
curve can be fitted to the boundary.
-
Boundaries can be snapped to other layers, faults or
intrusions.
-
Layers can contain multiple segments and may be discontinuous.
-
Points defining strata boundaries can be graphically edited
and deleted.
-
An unlimited number of lithologic symbols can be used to
represent different strata, more than 100 are supplied with
the program.
-
The foreground and background colors of the strata can be
specified.
-
The size of the strata symbol can be adjusted.
-
Strata definitions can be contained in the project or in the
master database.
-
Cross-sections can be imported and exported using a text
exchange format.
-
Cross-sections can be exported to the Windows clipboard, a
bitmap file, or a metafile.
-
Standard Windows new, open, save, and print commands.
-
An unlimited number of floating paragraph text boxes can be
added anywhere to a cross-section. The background and frame
colors can be specified individually for each text box.
-
An unlimited number of lines,
poly-lines, arrows, and
rectangles can be added.
-
An unlimited number of bitmap files can be imported into a
cross-section. These files can contain logos, site maps,
sample pictures, etc.
