WinFence can be used to graphically create detailed, full-color,
cross-sections and fence diagrams quickly and easily. The program can
be used to interpret and map soil and rock layers, contamination,
fossils, minerals and hydrocarbons.
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.
After the cross-section had been created it can be displayed in 3D
along with other cross-sections in the project as a fence diagram.
Fence diagrams are used to depict the geology and stratigraphy of the
subsurface in 3 dimensions. Typically, fence diagrams show several
cross-sections that may intersect as well as boreholes and wells. The
3D fence diagram display can be panned, zoomed, and rotated. The
position of the user and the light source can also be easily moved.
A wide variety of strata can be used to create cross-sections. Types
of strata that can be used include layers, faults, lenses,
intrusions, and alteration zones (mineralization, contamination,
hydrocarbons). Very detailed and complicated stratigraphy can be
represented and easily drawn. Layers can contain multiple segments to
represent uncomformities and highly faulted zones.
A unique snapping approach can be used to add layer, alteration zone,
intrusion, and lense boundaries. This approach allows the boundary of
one strata to be fixed to the boundary of another strata. Making the
input of strata boundaries quick and accurate. Boundaries can be
partially drawn and partially snapped. Snapped boundaries can include
one or more different strata. In addition to snapping, strata
boundaries can be assigned to the strata above or below.
Projects are displayed using a geographical information system (GIS).
The GIS displays a project location map that can be used to display
and edit boreholes and cross-sections. In addition, site features and
AutoCAD files can also be displayed. The project location map can
also be printed to be included with the cross-sections and fence
diagrams.
The format of the cross-section is controlled by a template, that can
be easily edited and customized. Templates are used to specify the
format and position of the cross-section, title bar, legend block,
location map, and scale bar. Company logos, bitmaps, text paragraphs,
lines, arrows, and rectangles can also be added to templates. Once
the template is created it is available to all projects. WinFence
comes with several previously created templates, that can be further
customized.
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 the borehole in WinFence.
WinFence works in conjunction with WinLoG to ensure a seamless
exchange of data.
All cross-section data for a project is stored in a Microsoft Access
database. This database allows for the quick storage and retrieval of
cross-section data and can be interfaced with a variety of other
programs. There is no limit to the number of projects and cross-
sections that can be stored in the database. The database is setup to
work across a network if desired, with each project stored in a
separate directory.
