Cementing Data

The Cementing form is used to record detailed information for each cement job performed on the Well.

Plug cement jobs are performed for a variety of reasons to isolate a portion of the Wellbore from the Wellbore above.

Primary cementing is performed immediately after the casing or liner is run into the hole. Its objective is to provide zonal isolation to prevent migration of formation fluids in the annulus and help protect the pipe by safely anchoring and supporting the string. Secondary cement jobs are performed after the primary cement job.

Squeeze cement jobs are performed to force a cement slurry under pressure through holes or splits in the casing/wellbore annular space. The slurry then flows into a permeable formation or fracture and hardens thus sealing that formation interval from the well.

Cement jobs can be recorded from the surface and subsurface Activities link or by selecting the cement skid on the offshore canvases or the cement truck on the land canvas.

The Cementing form allows the user to add, review, modify and delete cement jobs on a daily basis.

Wellbore Schematic Note: Use the wellbore schematic, built into the Cementing 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.

The Copy To Library button is used to copy cement jobs to the Cement Library. This enables users to copy previously entered cement jobs and use them as a template for other cement jobs. All data is copied to the library except data entered in the Tests section and certain job date/time information.

The Copy From Library button is used to import cement jobs from the Cement Library. This enables users to import an existing cement job template into the current Cementing report.

Warning! All existing data in the current Cementing report will be overwritten except the Tests, Isolated Intervals, Job Activity and Work Strings section.

The Job area defines the job type and basic information that relates to the cement job.

Select the Job Type from the picklist to define whether the cementing job is Plug, Primary or Squeeze.

When the Plug option is selected data can be entered in the Plug area. Otherwise, the Plug area is read-only.

When the Squeeze options is selected data can be entered in the Squeeze area. Otherwise, the Squeeze area is read-only.

Use this picklist to define the casing string that was cemented. Selections available in this picklist are defined in Casing reports dated on or prior to the Cementing report date.

If the cement job is not related to a specific casing assembly, select "None" from the picklist.

Note: If Casing reports have not been created for this Well, the Assembly Name picklist will be empty. 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 will not appear in the picklist.

When the Casing Assembly is selected the MD Landed, Hole Size and Casing Size are copied over from the Casing report.

The Plug area is only available when Plug has been selected in the Job Type picklist. Enter the details for the plug job in the corresponding fields.

The Squeeze area is only available when Squeeze has been selected in the Job Type picklist. Enter the details for the squeeze job in the corresponding fields.

Select the wellbore opening type from the list options listing the Opening Type, MD Top and MD Base. This list is populated from the Wellbore Openings tab in the Wellbore Properties dialog.

The Stage No/Type picklist is populated by each Stage entered in the Stages section.

A Details link appears in each row of the Stages spreadsheet. This link opens the Stage Details window, where the Stage data, such as MD Top, is entered.

The Fluid Pump drop down picklist is populated with a list of Fluids entered in the Fluids spreadsheet. This picklist also includes the Fluids Name, Type and Density.

A Details link appears in each row of the Pump Fluids spreadsheet. This link opens the Pump Fluids Details window, where the details of a the pumped fluids and foam are entered.

A Slurry link appears in each row of the Fluids spreadsheet. This link opens the Slurry Details window, where the Slurry and Rheology data is entered.

This is an editable calculated field that is calculated as follows:

Excess Slurry Volume = Total Slurry Volume * Excess Slurry Percent

This is an editable calculated field that is calculated as follows:

Total Water Volume = Sacks Used * Mix Water Ratio (for example, sack * gal/sack = gal. is a volume)

A Additives link appears in each row of the Fluids spreadsheet. This link opens a window where Additives can be entered in the Additives spreadsheet.

A Slurry Tests link appears in each row of the Fluids spreadsheet. This link opens the Test Details window, where Test data can be entered in the Tests spreadsheet.

IMPORTANT! This tab is disabled unless the TopBaseSlurryAndTest and TopBaseSlurryAndTestCodes system settings have been configured in the EDM Administration Utility. These system settings are used to configure the Cement Stage MD Top and MD Base fields to calculate based on the Slurry MD Top and Slurry MD Base of a defined fluid(s) entered in the Pumping Schedule.

A Dials link appears in each row of the Fluids spreadsheet. This link opens the Dial Details window, where details can be added to the Fann Dial spreadsheet.

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

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

The Show Today, Show Wellbore and Show All buttons are used to filter the list of Work Strings available on a form.

Note: These filters only show strings that existed from the end of the current reporting day back. It does not show strings entered on future dates.

When selected the Show Today button displays only strings captured during the current reporting day.

When selected the Show Wellbore button displays only strings recorded for the selected wellbore.

When selected the Show All button displays all strings for the current well.

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.

Copy from Library

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

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

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.

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

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.

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.
