Only the most commonly used sections of the Well Planning Report are covered in this training manual. For more information on specific sections in the Well Planning Report please refer to the online help.
Integration Note:
Well Planning reports are associated with a Design. This allows for natural integration with data created and calculated by Landmark's other well planning applications: COMPASS, CasingSeat, StressCheck, and WELLPLAN.
General Section
The General section records the Well Planning team's summary information about the Well Design. This section is divided into the following areas: General, Environmental Considerations, BOP Equipment, Logistics, and Location Map.
The Design field is a read-only field, which displays the name of the Design associated with the Well Planning Report. The Design is selected and/or created during the Report creation.
The AFE Number picklist contains the number's of each Cost Estimate and AFE report created in the same Event. Selecting the AFE will populate the AFE Total field with the total costs for all rows in the AFE Cost Estimates Spreadsheet.
The Objective field is populated by the Event Properties dialog. This field is greyed-out in the report and can only be changed from the Event Properties dialog.
Use the Environmental Considerations area to record wind and sea variables if an offshore Well is being planned or weather conditions on land including inability to drill in certain seasons.
Use the attachment button located at the bottom of the General section to attach location map documents. For information on attachments, see “Attachments in OpenWells” on page 3-94.
Planned Operations Section
The Planned Operations section enables the Well Planner to record the planned sequence of operations for a Well, based on existing data from similar Wells. Operations may be defined for Phase or Operation (Code) levels.
Critical Path Totals Area
The Critical Path Totals summary area displays the sum of all corresponding fields in spreadsheet rows flagged as critical paths dependent (CPD). All fields in this area are calculated fields and cannot be edited. The calculations for these fields are outlined below. The following total fields appear in this area:
• Target Duration - Sum of the agreed target time for the activity from the DWOP process.
• Technical Limit Duration - Best performing phase/well for all planned phases. The field is calculated by dividing the "Best Case Scenario" Offset Well's, Hole Section Length by the Technical Limit ROP for each equivalent Planned Operation. This calculation does not occur until data is entered into the MD From and MD To fields for the Planned Operation.
Average Offset Well Duration - Total average performance time for each operation determined from selected offset wells. This field is calculated by dividing the "Best Case Scenario" Offset Well's, Hole Section Length by the Avg Offset ROP for each equivalent Planned Operation. This calculation does not occur until data is entered into the MD From and MD To fields for the Planned Operation.
The Planned Operations spreadsheet is used to enter the planned operations for the Well. Each step of the Well operation may be documented. These steps can be directly associated to actual operations in the Daily Operations data entry form. When a phase is entered in the spreadsheet OpenWells uses the entered information to calculate the "Best Case Scenario" from the Offset Wells section and displays these details in the Technical Limit Analysis area (described below).
Technical limit calculations are performed at the Phase level only. For more information see “Technical Limit” on page 2-23.
The Critical Path Dependency (CPD) checkbox is an indicator used to flag activities required to complete the well operation. Offline activities may also be documented in the plan, which may be performed off-line or concurrent to the critical path operation. By default this checkbox is activated.
If the operations step entered in the row is part of the critical path activate the CPD checkbox. Once activated the values for Target Duration, Technical Limit Duration, and Avg Offset Well Duration are added to the corresponding Critical Path Totals fields located in the Critical Path Totals area above the spreadsheet.
The Step number column records the planned operations sequence number, which may be indexed to each actual activity.
Note:
The Technical Limit Duration and Average Offset Duration calculations can be performed using the Calculate ROP/Duration From Offsets button.
Enter the planned operation start date and time in the Activity Start Date/Time field.
Use the Cost Class, Cost Code, and Cost Subcode fields in the details area below the Planned Operations spreadsheet to record the associated planned operations to particular cost codes.
Hole Plan Section
The Hole Plan section is used to record hole section information, progress, and costs information, which can be used for comparison purposes in the planned vs. actual, depth vs. days, and cost vs. days performance graphs.
The Totals area displays the sum of all corresponding fields in the details area for the Hole Plan spreadsheet below. All fields in this area are calculated fields and cannot be edited.
The Generate from Planned Operations button automatically populates the Hole Plan with data entered in the Planned Operations section based on unique activity Phases.
Casing Program Section
The Casing Program section is used to record the planned sequence of Casings or Liners run in the hole. If the associated Design has been created and populated by CasingSeat or StressCheck, data entered in these applications will appear in the Casing Program section.
The Components spreadsheet makes use of a detail spreadsheet below it to record components which make up the casing or liner assembly in the order in which it would be run in the hole.
The Select from Catalog button appears in the Component area. This button can be used to select casing or tubing components from an available catalog.
For information on using a catalog, see “Catalogs” on page 2-15.
Note:
This section is read-only when the associated Design is locked or open in another application.
A Locked checkbox appears at the bottom of the Casing Program section, below the tabs. This checkbox indicates whether the associated Design has been locked. If the checkbox is activated the Design is locked and all information in the section is grayed-out. A Design can be locked or unlocked through the Design Properties dialog. This dialog can be accessed through the Engineer' Desktop applications such as, COMPASS, CasingSeat, and StressCheck.
Cement Program Section
The Cement Program section is used to record the cementing requirements for each casing or liner cemented in the hole.
The Casing Name picklist is populated by casings that have been entered in the Casing Program section of the Well Planning Report.
The Case Name picklist contains a list of Cases (within the same Wellbore) which have been created in other ENgineer’s Desktop applications (e.g., WELLPLAN). If there are no Cases created for the Well the picklist will be set to None.
