The NPT/Equipment Failure Properties dialog is used to enter unplanned event information for equipment failures and/or non-productive time. This dialog is available from the following locations in OpenWells® software:
Time Summary section of the Daily Operations report - Equipment Failures and Non-Productive Time are created from the Time Summary section.
Associated Data Viewer - Equipment Failures and Non-Productive Time appear in the Associated Data Viewer when their Event node is selected.
The NPT/Equipment Failure Properties dialog contains the following tabs:
Use the General tab to record the type of failure, the system in which it occurred and the failure depth and location.
Unplanned Event Type
The Unplanned Event Type area defines the type of unplanned event. The following options are available:
Equipment Failure - This option is used to describe Equipment Failures that do not affect the primary Rig Operation. This option enables the rig site supervisor to document any equipment failures that occur during off-line activities. Combined with operations equipment failures (that cause NPT), OpenWells software enables all equipment failures to be thoroughly documented. The NPT tab is not available when this option is selected.
Equipment Failure with NPT - This option is used in the event of an Equipment Failure which causes Non-Productive Time and which delays construction of the Well or Well Operation. These events result in remedial operations enabling the Rig to return to operation being performed at the time of the equipment failure.
NPT (No Failure) - This option is used to document the delay of the primary Well Operation that does not coincide with an equipment failure. The Equipment Failure and Obstructions tabs are not available when this option is selected.
NPT Activities
The NPT Activities area is used to record the activities, which define the start and end of a Non-Productive Time event. The Start and End picklists are populated with activities entered in the Time Summary spreadsheet.
Start Date/Time and End Date/Time in Event Area
For an Event causing NPT, the Start and End Date/Time fields appear greyed-out. These greyed-out fields are defined by the NPT Activities Start date (i.e., starting date and time of the Start activity) and the End date (i.e., ending date and time of the End activity). During the course of an NPT event, the End date/time may be empty until the end of the event has been identified.
Gross Time
The Gross Time field is an editable calculated field. Gross Time can be calculated in the following two ways:
For an unplanned event that does not cause NPT, this field is calculated based on the difference between the Start Date/Time and End Date/Time fields in the Events area.
For an unplanned event causing NPT, this field is calculated based on the Start and End Activity fields in the NPT Activities area.
Productive Time Adjustment
The Productive Time Adjustment field is only available for an event causing NPT. This enables the user to document the amount of constructive time that may occur within an NPT event.
Nested NPT
Nested NPT field is calculated based on the Net Times of all NPT activities "nested" within the current NPT event. For information on NPT Levels and "nested" NPT, see the NPT Level field's explanation below. For more information, see the Nested NPT topic.
Net Time
The Net Time field is calculated as follows:
Net Time = Gross Time - Productive Time Adjustment - Nested NPT Time
Create User
The Create User field is a grayed-out field populated by the name of the user who created the Equipment Failure/NPT event.
Total Gross Cost
The Total Gross Cost calculates the cost for the current Equipment Failure and/or NPT and the Net Costs of all "nested" Equipment Failures and/or NPTs. This field is calculated as follows:
Total Gross Cost = Net Time * Day Rate / 24 hours
Total Net Cost
The Total Net Cost calculates the net cost for the current Equipment Failures/NPT. This field is calculated as follows:
Total Net Cost = (Net Time * Day Rate / 24 hours) + Contractor Cost + Other Cost + Equipment Cost
Use the NPT tab to record the specifics of the Non-Productive Time event. This tab is not available when the Equipment Failure option is selected in the General tab.
This field defines the level of non-productive time for the activity.
Level 0 - This level defines the activity as productive.
Level 1 - This level defines the activity as the first NPT level
Level 2 and on - This level defines a NPT incident, which occurs during the previous Level's NPT (i.e. Level 1).
A NPT event that occurs within the interval of another NPT event is considered "nested".
Tracking Number
The Tracking Number field defines the non-conformance event number used for tracking purposes. This field is populated based on the Well Name and the Activity Start Date and Time. The date and time are formatted according to the PC's Window's Regional Settings.
Tracking No. = Well Name + Date + Start Time (e.g. 22/30a-AC (Scoter) 05/04/2004 09:00)
Contractor Panel
The Contractor panel enables the user to document the rig contractor’s summary of the equipment failure. Root cause assessment fields enable the user to provide reasons for the equipment failure occurrence. For downhole failures, additional information related to equipment type, location, failure type and metallurgy may be recorded.
Use the Equipment tab to describe the equipment failure that has occurred. This tab is not available when the NPT (No Failure) option is selected in the General tab.
Use the spreadsheets in the Obstruction tab to record assemblies and other tools that are left down-hole as a result of an equipment failure.
This tab is not available when the NPT (No Failure) option is selected in the General tab.
This section uses a Details Spreadsheet to capture information about the lost assembly and components.
For information on using spreadsheets in OpenWells see the Spreadsheets topic.
Add Row
Use the button to add a row to the spreadsheet.
Insert Row
Use the 
button to insert a row above the selected row.
Delete Row
Select the row to be deleted and click the 
button. The entire row must be selected by clicking on the row number.
Editing an Existing Row
To edit an existing row, select the row and enter the necessary changes in the Details area below the spreadsheet. Three spreadsheets appear in the Obstructions tab. The contents of each spreadsheet is dependant on the row selected in the spreadsheet appearing above it.
Split Pane Bar
For information on using the Split Pane bar see the Detail Spreadsheets and Tables topic.
Order Buttons
Use the 
and 
arrows to reorder rows in the spreadsheet.
The Close Out Comments tab is used to describe the final outcome of the Equipment Failure / NPT event.
The Close Out section enables the engineer to describe the final outcome of the NPT or Equipment Failure event. Information supported includes current Status, Reviewer, Closed check box, Closure Date, Name of user who Closed out the Event, Comments, Conclusions, Preventative Actions and Learning Points.
Attachments
Attached documents can be associated with an Equipment Failure and/or NPT using the Attachments button ( 
) appearing at the bottom of the General tab. For information on using this button see the Attachment Functionality topic.
Lessons Learned
Lessons can be attached to an Equipment Failure and/or NPT using the Lessons button ( 
) appearing at the bottom of the General tab. Lessons added to the Equipment Failure/NPT dialog appear in the Associated Data Viewer when the associated Well node is selected.
The Lesson button allows the user to create and view a Lesson. For information on creating a "New Lesson" see the Lesson Command topic. To view a current Lesson select the Lesson Name from the button picklist.
Note: Only one Lesson can be associated with an Equipment Failure/NPT event.
