The LogPlot8 program has a Data Editor window that uses tabbed datasheets to organize the different kinds of information that can be plotted on the graphic log.
This section discusses how you set up the datasheets themselves and enter data into them; click on a link for more information.
BH Info Datasheet

Numeric Datasheets
Lithology Datasheets

Notes
Tips
BH Info: Required. Used to enter the depths represented at the top and base of the data. This is the only required datasheet. You can also define the XY location coordinates and elevation for the borehole, and enter extended comments.
Edit Notes: Used to enter extended, wrappable text, such as hole-specific drilling notes or comments, for display in an Edit Notes field in the header or footer of the log.
Edit Text: Enter the short text labels to be plotted in the changeable Edit-Text fields in a log header or footer (names, dates, locations, etc.).
Interval Text: Enter depth intervals (top and base) and one or more columns of alphanumeric data to be plotted in Interval Text column(s) in the body of the log.
Point Text: Enter depth points and one or more columns of alphanumeric data to be plotted in Text column(s) in the body of the log.
Vertical Text: Enter depth intervals (top and base) and text to be plotted vertically in Vertical Text column(s) in the body of the log.
Interval Data: Used to enter depth intervals and one or more columns of numeric data to be plotted as Bar Graphs, and/or as labels in a Bar Graph Values column, and/or as text in an Interval Text column in the body of the log.
Point Data: Enter depths and one or more columns of numeric data to be plotted in a Curve column, Cross-Plot Curve column, or Text column in a log.
Time Data: Enter depth intervals, sampling dates, and one or more columns of numeric data to be plotted as Bar Graphs, and/or as labels in a Bar Graph Values column, and/or as text in an Interval Text column.
Lithology: Enter depth intervals and associated lithologic keywords and descriptions for those intervals, to be plotted as patterns in a Lithology Pattern column and/or as text in a Lithology Description column on a log.
Interbed: Enter specific depth interval(s) for interbeds that will overplot an existing Lithology Pattern column.
Percent: Specify the keywords for the rock types to be represented in a Pattern Percent column, and list the depth intervals and the percentages of each rock type.
Bitmap: Enter the name of one or more graphic image files to be inserted into a Bitmap column in the body of the log, and the beginning and ending depths at which they should be plotted.
Fillbar: Enter depth intervals at which vertical pattern bars will be plotted in a Fillbar column in the body of the log.
Fracture: Enter depth points, dip direction and angle, color, aperture (thickness), and radius (extent) of downhole fractures for display in a Fracture column.
Point Symbol: Enter depth points, vector symbols, and captions for display in a Symbol column.
Symbol: Enter depth points or intervals, vector or raster symbols, and symbol size for display in a Symbol column.
Tadpole: Enter depth points, azimuth bearing, dip angle, color, and value for display in a Tadpole column.
Water Levels: Enter depth intervals, aquifer name and sample date, for display as filled bars and/or graphic symbols in a Water Level column.
Construction: Enter the depth intervals, inner and outer diameter measurements, and keywords for the materials to be displayed in a Construction column.
Horizontal Line: Enter specific depth(s) at which one or more horizontal lines are to be plotted on the log.
Orientation: Enter downhole survey measurements (depth, bearing, dip) for non-vertical wells. Although LogPlot always displays wells as vertical, the depth/elevation Scale Bar allows display of true vertical elevations/depths down the log instead of/along with observed depths. In addition, Curve columns can display true vertical depth based on the survey data.
Scale Table: Used to define custom scale intervals for Curve columns.
Your LogPlot data files may contain virtually any number and combination of the available data items.
- If all of the items in the data file have corresponding items in the current log design, compiling the log will deliver a graphic log with all data items represented.
- If your data file contains fewer data items than are contained in the current log design, the un-referenced portion(s) of the design will simply be left blank when the log is compiled. For example, if your data file contains only lithologic descriptions, and you compile using a log design that contains description and bar graph columns, the bar graph columns will simply be left blank.
- If your data file contains more data items than are contained in the current log design, the extraneous data items will simply be ignored. For example, your data file contains both lithologic description and quantitative interval data, and your log design contains a lithology pattern column only, the quantitative data will simply be ignored during compiling.
- You can even compile a data file that has no data yet inserted! The compiled log will simply contain blank columns.
- To cross-check the tabs in the current data file against the entities in the current log design, use the Data Editor's Data | Check Data against Log Design menu option.
- To update the data file with changes in the current log design use the Data Editor's Data | Update Data File from Log Design menu option.
The LogPlot program was shipped with a variety of demo data files (*.Ldat8) that illustrate the use of the datasheets. These files were installed in Documents\LogPlot8 Data\Samples folder. Feel free to refer to these files as you read through this documentation and as you construct your own data files. (Each data file also has an associated LogDesign format file [*.Ldfx8] for your reference in designing logs.) See the sample file summary in the Reference section.
- Data Editor Files for details how to handle the LDAT8 files themselves, to add and remove the datasheets.
