Recording Non-Productive Time (NPT) Data

Non-Productive Time (NPT) Data

The following workflow illustrates how NPT data is entered using the interactive well site.

To learn more about calculations, features and other special fields appearing on this form, see the Non-Productive Time (NPT) Data topic.

Note: Users must have the appropriate permissions to add, modify, view or deleted NPT data. For more information, see your OpenWells® Administrator.

Cut, Copy, Paste, Delete Note: Users can cut, copy, paste or delete a row in a spreadsheet, by selecting a spreadsheet row number and right-clicking on the row. NOT all spreadsheets support the cut, copy, paste or delete features. But, data can be copied from any spreadsheet and pasted into an external application, such as Note Pad or Excel.

The following workflows are covered below:

Record a NPT Incident

NPT incidents that are or have occurred during the current Reporting day appear in a spreadsheet. Users can filter the spreadsheets to see a historical view of all NPTs entered for the wellbore to surface, NPTs for the current wellbore or NPTs for the current day. Note: These filters only shows NPTs that existed from the end of the current reporting day back. It does not show NPTs entered on future dates.

The Wellbore name appears at the top of the form to identify the selected wellbore being viewed. Any new NPTs added at this time will be added to this wellbore.

  1. From the interactive well site, select the Daily Operations link and click on the NPT link in the list that appears.

    Note: The form can be configured: to show the History button, which when selected launches a form with the filter buttons (Show All and  Show Today); or to show the filter buttons (Show All and Show Today) on the initial form.

  2. Click the History button to see a historical view of all NPTs entered for the event or NPTs for the current day.

  3. Click the Show All button to view all NPT incidents that have occurred over the duration of the event.gif Event.

  4. Click the Show Today button to view only NPT incidents that are occurring or have occurred during the current Reporting day.

  5. To add an attachments to a NPT row in the spreadsheet, click on the attachment cell and select New... from the menu that appears.  See the Using Attachments in Spreadsheets topic.

  6. To create a new NPT, click the Record NPT button.

  7. Select the timed activity start date where the NPT incident occurred and click OK.

Enter NPT/Equipment Failure Details

To view the details of a NPT/Equipment Failure for an existing NPT incident, select the Details hyper link in the NPT Details column for the NPT row.

In the General tab...

  1. Select NPT incident type in the Unplanned Event Type area.  

  2. Enter a Title defining the NPT. Along with the date, the title identifies the incident in the NPT Summary dialog in OpenWells Classic.

  3. Enter a Description of the NPT. The description is displayed in the NPT form's spreadsheet and is useful in quickly identifying the incident.

  4. Enter time for any "productive activities" that occurred during the duration of the incident in the Prod Time Adj (Productive Time Adjusted) field.

    For example, during an incident while waiting for equipment to arrive, some drill pipe is picked up and racked back in the derrick. This would have been carried out later on in the planned operation but was brought forward to minimize the impact of the incident. The time taken to pick up the pipe should be recorded in the Prod Time Adj field.  

    Important Note!     This field is used to adjust the Net Time of the incident and therefore affects calculations.

In the NPT tab...

This tab is not available for Equipment Failure Event Types.

  1. Select the Failure Location, Root Cause Type, NPT Cause and NPT Description to further define the type of NPT occurring. Each of these items is displayed in the NPT form's spreadsheet and is useful in quickly identifying the NPT incident.

  2. The NPT Level field is used too identify the primary (first occurrence of) NPT and those that began after the primary incident's start, but before the incident's end.

    Use the following guidelines to define the appropriate NPT Level.

To learn more about Nesting, see the Nested NPT topic.

In the Equipment Failure tab...

This tab is not available for NPT (No Failure) Event Types.

  1. Enter the details of the last known inspection performed on the failed equipment and Failure details.

In the Obstructions tab...

  1. Use the spreadsheets to record assemblies and other tools that are left down-hole as a result of an equipment failure. This section uses a Details Spreadsheet to capture information about the lost assembly and components. Details entered in this tab also appear in the Wellbore Properties Obstructions tab.  

    Cut, Copy, Paste, Delete Note: Users can cut, copy, paste or delete a row in a spreadsheet, by selecting a spreadsheet row number and right-clicking on the row. NOT all spreadsheets support the cut, copy, paste or delete features. But, data can be copied from any spreadsheet and pasted into an external application, such as Note Pad or Excel.

  2. To add an obstruction, click the addrow.gif Add Row button in the Wellbore Obstructions spreadsheet.

  3. Enter the details of the obstruction in the spreadsheet.

  4. To further define the obstruction, add rows to the Obstruction Status  spreadsheet. Each row added to this spreadsheet is "owned" by the currently selected Wellbore Obstruction.

  5. To further define the obstruction status, add rows to the Obstruction Contents spreadsheet. Each row added to this spreadsheet is "owned" by the currently selected Obstruction Status.

In the Close Out/Comments tab...

  1. Once the incident has ended, record details of follow up investigations and results in the Close Out/Comments tab.

  2. Select the attachmentdropdwn.gif Attachments icon to add attachments associated with the incident to the Report (e.g., reports, photos, etc).

    Note:     Attachments to NPTs are not visible in the Associated Data Viewer. However, when the Event is selected in the Well Explorer a list of NPTs for that Event are displayed in the Associated Data Viewer. Double clicking a NPT in the Associated Data Viewer will open the NPT/Equipment Failure Properties dialog for that NPT. Within here under the Close Out/Comments Tab the Attachment button indicates the number of attachments that are associated with that NPT.

  3. Select the lesson-btn.gif Lessons button to add and select New Lesson... to add a Lessons Learned item. For more information see the Lessons Learned topic.

    Note:     Once created the Lesson will also be available from the Associated Data Viewer when the Well is selected in the Well Explorer tree.

  4. Click OK to save changes and close the dialog.

Import Spreadsheet Data

To import data into a spreadsheet:

  1. Right-click anywhere on the spreadsheet and select import.gif Import from the menu that appears.

  2. The Import Wizard appears.

    Note:     Imported data will create a new row in the spreadsheet. An existing empty row will be left empty.

  3. Select the source of the data to be imported.

  1. If the data has been copied to the Windows clipboard select the Clipboard option.

  2. If the data is located in a file select the File option.

  3. Once the File option has been selected click the Browse button to navigate to the location of the file.

  1. Click Next.

  2. Select the delimiter that best suits the format of the data. The following options are available:

  3. Tab - The wizard detects the location of all tabs within the data and separates the data into columns accordingly.

  4. Comma - The wizard detects the location of all commas within the data and separates the data into columns accordingly.

  5. Other - Enter an appropriate delimiter in the field provided any keyboard value can be entered in this field. The wizard detects the location of the newly defined delimiter within the data and separates the data into columns.

  1. A sample view of the data using the selected delimiter is displayed below the options.

    Note:     A paragraph return within text is read by the wizard as a new row for the data.

  2. Click Next.

    The next step is used to organize which columns the data will be placed into. The Wizard displays the data into Source Columns. These source columns are defined by the type of delimiter selected in the previous step (i.e., Tab, Comma, Other). Each source column contains a picklist that allows the user to define the destination of the data.

  3. Use the picklists to select the destination column for the imported data.

    Note:     If a Source column is not specified the data contained within it will not be imported.

  4. Once all columns have been defined, click Finish.

    The imported data appears in new rows of the spreadsheet/table.
