Checkshot survey format

Checkshot survey files may be written as delimited fields (as in this example) or as fixed width columns. Tab delimited fields are not supported.

Header lines are ignored by the import process, but you may have one or more header lines in the file for identification purposes. When you import the file, you will specify the number of header lines for WinPICS to skip. The first three lines of the sample file are header lines.

All depths are assumed to be true vertical depths. Depths may be in feet or meters. Times may be in one way or two way time and the units may be microseconds, milliseconds, or seconds.

It is best to use a neutral reference elevation for your time and depth value such as seismic datum or sea level. This way you can assign checkshots to multiple wells without having to edit the reference elevation each time the checkshot is used. The reference elevations for time and depth values can be:

The data values may be written as a true vertical depth followed by time or vice versa. You specify which field is to be read for time and which is to be read for depth during import.
