Casing Data

The Casing form is used to define and track casing assemblies run downhole. Tallies of the casing string or tubing joints can be imported from the Pipe Tally area using the Import Pipe Tally... button in the Components section. Importing the Pipe Tally reduces time spent entering data and improves data integrity as information is only entered once for these two reports.

Once Casing data has been completed, the data selected from the Assembly Name picklist in the General section will appear in the drop-down menu list for the Assembly field in the General section of a newly created Cementing Report. OpenWells® software populates this picklist by searching the database for the String Type entries in Casing reports dated on or before the date of the Cementing report. If the Casing report is dated after the Cementing report, the Assembly Name for that report will not appear in the picklist.

A new Casing job must be created for every string run in the Well. Tubing strings should be entered in the Wellbore Equipment report.

Casing jobs can be recorded from the surface and subsurface Activities link, or by clicking on the casing pipe being pulled up onto the rig floor.

The Casing form allows the user to add, review, modify and delete the details of casing jobs.

Wellbore Schematic Note: Use the wellbore schematic, built into the Casing form, to verify the data being entered makes sense. Right-click the schematic to magnify the image.

TIP! If the schematic is not looking as you expect, check the current Reporting Standard to verify the assembly and status dates and times are within the current reporting standard correct.

This section defines buttons, calculated fields, read-only fields, some drop down picklists and other areas with special functionality.

Note: Data selected in this field appears in the picklist for the Assembly field in the General section of the Cementing and Perforation forms. OpenWells populates this picklist by searching the database for Assembly entries in Casing reports dated on or before the date of the Cementing and Perforation reports. If the Casing report is dated after the Cementing and Perforation reports, the Assembly for that report will not appear in the picklist.

The Located Inside picklist is populated by Casing and Wellbore Equipment strings run in the Wellbore on or before the current reporting date. This picklist displays the casing/wellbore assemblies name, size, measured depth top and date in hole.

The MD identifies the current day's measured depth for the Wellbore. The value appearing in the MD field comes from the most recent Daily Operations report's General section MD field.

By default, the True Vertical Depth (TVD) field is calculated based on the Survey Header tie-on and the Survey Stations entered in the Survey section.

The Assembly Length is calculated based on the sum of all the component Lengths entered in the Components section of the Casing report.

The Elevation field displays the elevation of the currently selected "viewing datum". This value is populated from the Well Properties Depth Reference tab.

Note: Changing the "viewing datum" will not change the Elevation until the report it closed and reopened.

If planned casing components have been entered in a Well Planning report, use the Import Planned/Prototype String button to import the components into the Casing report. Once imported the actual run lengths and tally order can be edited.

Click the Import Planned/Prototype String button. The Select Assembly dialog appears.

Note: Casing assemblies, created in the Casing Program section of the Well Planning report and in the PROFILE, CasingSeat and StressCheck applications, populate the Select Assembly dialog.

Select the assembly to be imported into the report.

Click OK. The assembly and its related components are imported into the Casing report.

Use the Import Pipe Tally... button to access a list of all available pipe tallies in the Event that can be imported into the Casing component spreadsheet. For more information, see the Import Pipe Tally topic.

The Copy String from Library button copies a assembly selected from the library to the current Components spreadsheet. When this button is selected the Select String dialog appears.

A new row is added to the spreadsheet containing data from the original Assembly.

This button allows casing assembly to be added to a library, where it can be used later to create new Assembly Runs.

Enter a String Name that clearly identifies the selected assembly string and click OK.

The move up and down buttons allow users to change the order of individual components. To change the order, select the component row and click the Move Up or Move Down button until the component is in the correct position in the spreadsheet.

In the event that a string's components have been entered in the wrong order (e.g., top to bottom instead of bottom to top), the Flip Assembly button allows a user to quickly fix this mistake and reverses the entry order of the components.

The Catalog button is used to select a component from a compiled list of available components and their properties. For more information, see the Catalogs topic.

Some selection types are supported by EDM™ catalogs. When these component types are selected, a Catalog Selection dialog appears enabling the user to select the component from lists populated from the catalog. For information on using a catalog, see the Catalogs topic.

The Auto Catalog Select command is activated the Catalog Selection dialog automatically appears by default.

For each component, select the Section Type and Component Type from the picklists.

Some component Section Types are supported by EDM™ catalogs. When these component types are selected, a Catalog Selection dialog appears enabling the user to select the component. The Auto Catalog Select command defines if a catalog is automatically opened when the Section Type is selected. By default, the Auto Catalog Select option is active. Alternatively, select the Catalog button for the currently selected Component row.

Click the Details link to add or modify the details of the currently selected component in the Component's Details dialog.

The MD Base field is calculated by adding the Length of the string component to the MD Top.

Use the Create Obstruction button to define the casing assembly as an obstruction. This string is added to the Wellbore Obstruction spreadsheet in the Wellbore Properties dialog.

Only Assemblies that have a Status of INSTALLED appear in the Wellbore Schematic. The Partial Pulled options allows the user to model a partial pullout for a particular date. For a partial removal, data can be entered relating to the top and base measured depth.

When an Accessory is selected, the Catalog button allows users to select the accessory from a Catalog. The selected catalog items populate the spreadsheet. For information on using a catalog, see the Catalogs topic.

The Catalog can be set to automatically appear when a valid Accessory has been selected. Auto Catalog Select command is set in the Options dialog.

Show Hide Buttons

The Show Hide buttons are used to expand or collapse a data area. This feature allows users to view the entire details of a spreadsheet row or just the summary row.

For example, in BHA and Work String spreadsheets these buttons show and hide string components.

In the Costs spreadsheet these buttons show and hide daily cost details.

In the surveys spreadsheet, these buttons show and hide survey readings.

Copy To Library Button

This button allows work strings to be added to a library, where they can be used later to create new Work String runs.

Select the row to be copied and click the Copy To Library button.

The Save String to Library dialog appears.

Enter a String Name that clearly identifies the selected string and click OK.

The string is now available to be copied from the Library.

The Copy from Library button copies a work strings selected from the library to the current spreadsheet. When this button is selected the Select String from Library dialog appears.

Select the desired work string and click OK.

A new row is added to the spreadsheet containing following data from the original string:

the BHA No is a combination of the word "Copy and the name of the original BHA No,
the String Type (defined by the name of the Library item,
the current report date and the report date end time,
components of the original string.

Edit these fields to correctly reflect the name of the string going into the Well and the date and time the run took place.

Note: The Component Lengths most likely need to be altered when a work string is copied from the library.

Copy Previous Button

Prior to using this button, all work strings must be pulled.

The Copy Previous button copies a previously entered work string or planned work string into the spreadsheet.

When this button is selected the Select Assembly String dialog appears.

Use the Select Existing String to Copy tab to access BHAs and Work Strings recorded in EDM or use the Select Planned String to Copy tab to access a planned string recorded in EDM.

Navigate to the Wellbore containing the string to be copied using the Well Explorer tree or click the Well List tab at the bottom of the dialog to select by well name and wellbore name.

Select the Wellbore. A list of BHAs and Work Strings recorded for the selected Wellbore appears.

Select the string to be copied and click OK.

The selected string is copied into the spreadsheet.

Edit the BHA No and Date/Time In fields to accurately reflect the new string run.

Record Component Button

The Record Component Button adds a row to the Components spreadsheet.

Catalog Button

Flip Order Button

In the event that a string's components have been entered in the wrong order (e.g., top to bottom instead of bottom to top), the Flip Order button allows a user to quickly fix this mistake and reverses the entry order of the components.

Move Up and Move Down Buttons

Left in Well and Create Obstruction Button

If the work string assembly was dropped or stuck in hole, use this feature to create an obstruction. Click the Create Obstruction button to quickly create an obstruction. The work string will be listed in the Wellbore Obstruction section in the Wellbore Obstructions spreadsheet, with all of its components listed in Obstruction Components spreadsheet. When the Create Obstruction button is clicked the Left in Well checkbox is selected automatically.

Components (Enter Top to Bottom)

The direction in which components must be added to the Components spreadsheet is defined in the Compoents (Enter Top to Bottom) text. The direction displayed is defined by a system setting in the EDM Administration Utility.

MD In and Date/Time In

The MD In and Date/Time In fields define the depth and time at which the string is run "downhole".

The Date/Time In field automatically populates based on the date of the Daily Report date and the Reporting Standard selected for the Company (see Company Properties). For all subsequent rows, the Date/Time In field will be automatically populated with the data entered in the Date/Time Out field in the previous row.

MD Out and Date/Time Out

The MD Out and Date/Time Out define the work string as pulled.

Note: Before a new row can be added any Work String or Drillstring spreadsheets, the Date/Time Out and MD Out fields for the previous row must be entered. If these are not entered, the following message will appear, "The previous BHA/Work String has to be pulled out before you can add a new one."

Running and Pulling a String in the OpenWells® application

In the OpenWells application:

a string is considered downhole when both the MD In and Date/Time In have been entered
a string is considered "pulled" when both the MD Base and Date/Time Out have been entered
only one BHA or Work String can be run "downhole" at a time

BHA Number

The BHA No. field is used to identify the string run. For example, the BHA number can increment by one every time any component is changed. Individual Companies have their own rules for the BHA number.

Section Type and Component Type

For each component, select the Section Type and Component Type from the picklists.

Some component Section Types are supported by EDM™ catalogs. When these component types are selected, a Catalog Selection dialog appears enabling the user to select the component. The Auto Catalog Select command defines if a catalog is automatically opened when the Section Type is selected. By default, the Auto Catalog Select option is active. Alternatively, select the Catalog button for the currently selected Component row.

MD Top

The MD Top defines the top measured depth of the component. This field is calculated as follows:

For the first row, the value in the Top field is 0.0 based on the Depth Reference selected at the time the row was created. If the Depth Reference is changed the Top depth changes to reflect the new Depth Reference selected.

For all subsequent rows: Top = Previous MD Base

MD Base

The MD Base field defines the bottom measured depth of the component. This field is calculated as follows:

MD Base = Top + Length

Component Details Button

Click the Details link to add or modify the details of the currently selected component in the Component's Details dialog.

Top Set

The Top Set of the component is calculated by adding the lengths of the previous components to the MD Top.

This field automatically calculates the total time for each activity based on the From and To fields.

This field calculates the total time for all activities listed in the Job Activity spreadsheet.
