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. |
