General
Wellbore Properties
The General area is used to define properties of a new wellbore by providing a unique name for the wellbore. This dialog is also used to ‘lock’ Wellbore information. The default Reference Datum level for the Wellbore is also set in this dialog.
Special Fields and Functions
Side Track Number (ST)
If the Wellbore is a sidetrack enter the number of the sidetrack in the Side Track Number field (e.g., 01, 02, 03...). Otherwise, enter OH for Original hole or OO to designate this Wellbore as the initial hole for the Well.
Legal Name
The Legal Name that will be used to identify the Wellbore. This name must be unique within the Well.
Common Name
The Common Name that will be used to identify the Wellbore. This name must be unique within the Well.
Wellbore Label
The Wellbore Label can be used as an alternate name for the Wellbore.
Wellbore UWI
The Wellbore UWI field can be use to define the Unique Well Identifier for the Wellbore. Alternatively, the Bottom Hole Location Description can be used to identify the Wellbore UWI.
Bottom Hole Location
The Bottom Hole Location field is populated by the Bottom Hole Location Description defined as Primary in the BH Location Description area.
Reason
The Reason picklist identifies the reason for the creation of the new wellbore. For example, the original Wellbore would be defined as 'Main Wellbore'.
API Suffix Number
The API Suffix Number can be entered as follows:
the first 10 digits of the API Number define the Well location (i.e., state code, country code and Unique Well Identifier), see Well Properties General area, API Number
the eleventh and twelfth digits represent the Sidetrack code, (see API Suffix Number)
the thirteenth and fourteenth digits represent the Event Sequence (see Completion Properties General area).
Wellbore Type
Select a Wellbore Type from the drop-down picklist. This picklist is populated by the Company Properties, Wellbore Types area.
Vertical Section Area
The Vertical Section area is used to specify the vertical section azimuth of the wellpath. This azimuth is used to project a vertical plane from the Well Surface location onto which Wellbore position vertical section distances are projected. VSec values calculated in the Survey section of the Daily Operations data entry form are referenced to this azimuth.
Define the Vertical Section characteristics using the fields provided.
Origin N - The North (+, e.g., 1050 ft) or South (-, e.g., -500ft) distance from the wellhead to the local origin.
Origin E - The East (+, e.g., 400 ft) or West (-, e.g., -200ft) distance from the wellhead to the local origin.
Azimuth - The azimuth continuing the vertical plane on which vertical sections are projected.
Sidetrack from an Existing Wellbore Area
This area defines a wellbore as a sidetrack.
Parent Wellbore - If the wellbore is a sidetrack, select the wellbore that contains the tie-on point from the Parent Wellbore drop-down picklist.
TVD Kick Off (TVD KO), Kick Off North/South Offset (KO N/-S) and Kick Off East/West Offset (KO E/-W) - These three fields define the location in 3D -space of the sidetrack relative to the well surface location and current Reference Datum Level. These values are calculated using the measured trajectory of the parent wellbore. Trajectory measurements are recorded in the Survey Headers and Survey Stations entered in the Daily Operations reports or in the COMPASS™ application.
Locked Checkbox
The Locked checkbox prevents editing or deletion of the Well data. If this checkbox is activated and a Lock Data password has been specified the password must be entered before the Well data can be unlocked. Passwords are set in the Company Properties dialog.
For more information, see the Data Locking topic.
Project Data Locked Checkbox
The Project Data Locked checkbox is used to lock Well data entry fields that have been configured as Project Locked data. checkbox is not available until the Locked checkbox is activated.
This feature is only available when the ProjectLocking system setting has been set to true in the EDM Administration Utility For more information see the Project Data Locking topic.
Populate Initial Hole Section Group form Parent Wellbore Button
This button is used to copy over Hole Section information entered for the Parent Wellbore. The following requirements must be met to be able to copy Hole Sections:
A parent wellbore must be selected from the Parent Wellbore picklist.
Hole Sections must exist in the parent wellbore.
The kick-off point of the new wellbore must fall between the Kick-off Measured Depth and the Bottom Hole Measured Depth (on the Depth area) of the definitive survey header for the parent wellbore.
Note: The definitive survey header is set in the COMPASS application.
