Defining Well Path

Once you have defined the general information for a well (see Creating a New Well), you can add the well path information.

Open the Path tab

Open the Path tab
  1. Open the Path tab in the Configure Well window. This window is displayed once you have saved the general well information. 
  2. Alternatively, you can also open this window by going to the Well tab in the Control Panel, double-click the well item, and open the Path tab.
  3. Click New Well Path to add a well path for the well. The Add New Well Path window will be displayed.

Define a well with straight path

Define a well with straight path
  1. If the well is straight or you do not have the deviation information, select Straight Path at Type.
  2. At Name, type a name for the straight well path.
  3. Type the Surface X and Surface Y locations of the drill hole or the longitude/latitude. Alternatively, click the Select Lat-Long and/or CRS option to change the location data type from Surface XY to Lat-Long.

Note: Latitude and longitude coordinates must be entered as decimal degrees. For example, 37 deg 53' 06.44" must be entered as 37.885122. For help converting to decimal degrees, click here.

  1. If the well uses a different coordinate reference system (CRS) from the project CRS, click the Convert from button on the Coordinate Reference System conversion screen to convert the well CRS to the project CRS (see Converting CRS When Importing a Well).
  2. At Max MDKB, type the maximum value of the Measured Depth from Kelling Bushing (MDKB) for the straight well.
  3. Type any additional information about the well path in Notes.
  4. As you enter the information of the well path, you will be notified if there is any error or warning.
  5. Click OK. The well path added for the new well will be displayed in the Path tab. See the following example:

Define a well with deviated path

Define a well with deviated path

In addition to a straight well path, you can also define a deviated well path by importing a deviation survey file for the well (see Well Import File Formats for more details on the format of a deviation survey file). Insight now also supports horizontal and ascending wells. 

Note: Insight measures TVD as "depth below", so that increasing values mean an increase in depth. If your deviation survey appears to have TVD recorded as elevation (increasing depth is negative), an error will be displayed.

  1. In the Configure Well window, click New Well Path. This will open the Add New Well Path window.
  2. At Type, select Deviated Path. 
  3. At Name, type a name for the deviated well path. If you do not type a name, Insight will enter the name of the deviation file you import.
  4. Type any additional information about the well path in Notes. 
  5. At Deviation survey, click the Select File folder icon.
  6. Select the deviation survey file for the well and click Open. By default, information of the selected file will be displayed in Notes.
  7. Click the Preview the file eye icon to view the content of the file.
  8. As you enter the information of the well path, you will be notified if there is any error or warning. In this example, an error is detected and you need to configure the text importer.
  9. Click the spanner icon to Configure import parameters. See the following section:

Configure import parameters for deviation file

Configure import parameters for deviation file
  1. See if there is any error/warning indication at the bottom of the window. Adjust the text importer accordingly. Once it is error-free, click OK.
  2. The Coordinate Reference System conversion window will be displayed to allow you to convert the coordinate reference system (CRS) of the well to the project CRS. This is needed if the well CRS is different from the project CRS (see Converting CRS When Importing a Well).

Use X Offset and Y Offset as location columns

Use X Offset and Y Offset as location columns

For deviated well paths, Insight also allows you to import X Offset and Y Offset as the location values. 

  1. In the location columns, select X Offset and Y Offset.
  2. At Surface location, type the surface location of the well.
  3. Select the Offset Type as X/Y offset relative to previous sample or X/Y offset relative to surface location.
  4. Click OK.

Use inclination and azimuth as location columns

Use inclination and azimuth as location columns

Insight also handles inclination and azimuth as deviated wells input.

  1. In the location columns, select Inclination and Azimuth.
    Note: When TVD, Inclination and Azimuth are provided, the TVD column data will be ignored.
  2. At Surface location, type the X/Y or Longitude/Latitude surface location of the well.
  3. Click OK.

Add deviated path to well

Add deviated path to well
  1. Once you have added a deviation survey file and configured the import parameters, check if there is any more error or warning. Icon will turn green if there are no errors/warnings.
  2. Click OK. The deviated path added for the new well will be displayed in the Path tab. See the following example:
