Strata Log
www.alt.lu
Description:
The Strata (Stratigraphic) Log has been developed to handle and display chrono or
litho-stratigraphic columns (e.g. System, Series and Stage) in a single log column.
Manually entered text or text and color/pattern fill loaded from libraries can be
displayed in boxes limited by column width and Top and Bottom Depth. Any
number of columns can be handled. If text found in adjacent boxes is equal it will be
merged and displayed as single box.
Top and Bottom Contact styles can be assigned to each box boundary. In order to
highlight important zones (e.g. reservoir top/bottom) the user can allow contact
style lines to be drawn across the entire borehole document.
Data Format:
TopDepth, BottomDepth, DataCol1, DataCol2,…,DataColN,
TopContact, BottomContact
E.g.
The first two columns – top and bottom depth – are followed by a user-defined
number of stratigraphic data columns. Two columns containing information about
the top and bottom contact style complete each data row. When the data is
displayed cells with equal information will be shown as one text box.
