How to enter the BH Info Data
The LogPlot BH Info datasheet is used to define the depths at the top and base of the log, and the location coordinates for the drill hole (X and Y location coordinate, elevation and collar elevation). It also contains a text window for entering comments and notes that you can use for your reference.
Corresponding log design component: Elevations can be represented in Scale Bars. Coordinates can link to Static Text fields.
Corresponding RockWorks data table: Location
The BH Info datasheet iis created automatically each time a new data sheet is created. There can be only one BH Info datasheet per file. This datasheet is required.
Start Depth, End Depth: Enter the depth at the top and at the base of the log. They are used by the program to define the vertical extents of the log.
Depth values must be entered as positive numbers. If you import a data file from an older version of LogPlot, which permitted negative depths, the depths will be changed to positive values.
! These starting and ending depth values may span the entirety of your data or may list just a subset of your data in order to plot just a portion of your log.
Prior to compiling a log (Log|Compile a Log command) the program will read the top and base declared here and will display them as defaults. You then have the opportunity to override the default settings to plot more or less data.Easting, Northing: Eenter the x and y location coordinates for the top of the borehole.
You may use virtually any coordinate system that you wish, though if you will be exporting the data into RockWorks, you should be sure that the location coordinates are in the same units as you have defined for the RockWorks project.
If unknown you may set them both to 0.
Elevation: In this cell, enter the elevation at the top of the well, typically the ground surface. The program will use this to compute elevations if your log design contains an elevation scale bar.
If your log contains no scale bar that represents elevations in the log, you may enter 0.
If you intend to export your LogPlot data to RockWorks, you should be sure that the surface elevation units (meters or feet) are the same units as you have defined for the RockWorks project.
Collar Elevation: In this cell, enter the elevation at the top of the collar or casing of the well. If your downhole depths are measured from this elevation, you can specify this as you compile your logs.
If your log contains no scale bar that represents elevations in the log, you may enter 0.
If you intend to export your LogPlot data to RockWorks, you should be sure that the collar elevation units (meters or feet) are the same units as you have defined for the RockWorks project.
Comments: In this scrolling text box, you can enter reference information about the data file.
This is typically used to list the names of log designs, keywords, patterns, and/or symbols that correspond to the data file, and to note the vertical scale at which the log should be compiled.
These comments are not required.
