Entering Downhole Point or P-Data

The Borehole Manager P-Data (Points) table is used to enter numeric values which were sampled at single depth points (as opposed to depth INTERVALS) down the boreholes.  This might apply to downhole geophysical measurements (gamma ray), drilling rate, etc.  Leave this table blank if you have no point data. 

! This table does not accept text entries.  It accepts numeric values only.

See
Point Text (P-Text) for entry of textual (alphanumeric) data
Downhole Interval (I-Data) for information about entering interval-sampled numeric data
Time-Based Interval (T-Data) for information about entry of interval data sampled with date records

Accessing the P-Data Table

1. Access the Borehole Manager
2. Create a new project as necessary.
3. Create a new well if necessary, or click on the existing well to be edited.
4. Click on the P-Data table for the well.

5. Define the data columns if necessary: You can have multiple columns in this table, for your different P-Data components; use the P-Data Types button at the top of the table (or the Project Tables / Types Tables / P-Data Types item in the Project Manager) to define these. (More.)
    

P-Data Fields

Once you have the data columns defined, you can enter the measurements themselves. These instructions are for hand-entering the data; please see the links at the end of this topic for other options.

• Depth: Enter the depth for the first measurement for the well. 
  ! The depth units must be the same as the Vertical units you defined for the project (and which are displayed on the Location table). For example, if the elevation and TD for the hole are shown there in feet, then the depth listings here must be in feet as well.
  ! The depth values must be positive. 
  
  
• From Elevation / From Collar Elevation: Use this button at the top of the table to define for this borehole which datum your depths were measured from.
  • Choose Measured from Elevation if the depths were measured from the ground elevation (entered as the "Z (Elevation)" field in the Collar Coordinates tab). This is the default setting.
  • Choose Measured from Collar Elevation if the depths were measured from the collar elevation (entered as the "Collar Elevation" field in the Collar Coordinates tab).

• Column 1: Click in (or <Tab> to) the first column to the right of the depth and type in the measured value for that downhole point. 
  If you have no data, you can leave the cell blank. Blank cells will simply be skipped during processing. Only numeric data is permitted.
  
  
• Column 2 - Column x: Click in (or <Tab> to) the next column to the right of the first, and type in the measured value for that component, for that depth.  Repeat for as many columns as you have measurements for, for that depth.
  
  
• Move on to the second row, clicking in its Depth, and type in the measured depth to the second measurement for the well. Continue in this manner, specifying depths and measured values, for the entirety of your data.  Example:

There is no limit to the number of downhole points that you may list for each drill hole, though if you are creating solid models, the more points the slower the processing.
