Daily General Data

The Daily General form is used to record a Rig Supervisor's summary of the drilling or well services operation. In the office, the Operations Engineer or Manager can examine this section and review the main details of the operation. It is important to ensure that this section contains information that is both detailed and correct.

In addition the Daily General form displays the properties of the Daily Operations Report generated by OpenWells. Changing these properties affects all forms belonging to the Daily Operations Report. A list of these forms is displayed by the Daily Operations Data link.

Daily General data can be recorded from the surface and subsurface Daily Operations link.

The Daily General form allows users to add, review, modify and delete daily general data over multiple days from one location.

Some fields on this form are automatically populated from data entered in areas of the application, involve calculations performed by OpenWells® software or have other significant features.

This field defines the Date of the report and follows the guideline set by the Reporting Standard.

The Rig Operation drop down menu shows Rig currently associated to the Daily data.

The Daily Operations data can be locked by users with the correct permissions assigned by selecting the Locked check box.

Locking data from this location locks all data belonging to the Daily Operations Report. A list of forms affected is displayed by the Daily Operations Data link.

Note: If the Locked Data button in the General tab of the Company Properties window was set with a password, the Password Exists warning dialog will appear when a user chooses to lock a report that falls under that Company node. This password is then required to unlock the data.

This is the depth of the Well at report time. The Previous Day MD is populated with the measured depth entered on the previous day. This field is calculated at the time the Daily General form is opened for the first time and cannot be changed later (i.e., editing the MD value in the previous day's Daily General form has no effect on this field).

The MD field defines the depth of the Well at the reporting time. Reporting time is based on the Reporting Standard defined and varies depending on your Companies policies.

The depth entered here automatically populates many other fields in OpenWells including, but not limited to:

OpenWells uses the minimum curvature method in calculating TVD. The survey used in this calculation is determined by OpenWells as follows:

The Hole Size field is populated by the current Hole Section's Openhole effective diameter. OpenWells software identifies the current hole section using the report date and hole section start and end dates.

The Progress field calculates the measured depth advancement since the previous Daily Operations report. It is calculated by subtracting the Previous Day MD (measured depth of the previous Daily Operations report) from the measured depth (MD) value entered in the current report.

In the first Daily General form, a value must be entered in this field. A value can also be entered at the beginning of each Event in the Well.

Days from spud is the number of days since drilling commenced on the Well. This field can contain a negative number and can be different from the days on location if the Rig is moved on location before the Well is spudded. By default, the DFS field is automatically increased by one each day.

Days on location is the number of days since the arrival of the Rig on site. By default, the DOL field is automatically increased by one each day. This number can be negative if the Daily Operations report is created prior to arriving on location.

The Avg ROP field is calculated by dividing the Progress by Rotating Hours.

The MSICP field represents the maximum annular pressure that can be measured at surface with the current mud in the hole without applying a pressure greater than the leak off test.

Any time the mud weight changes from the AMW used in the leak off test, the user can put the Mud Weight in the Pressure AMW field in the Max. Allowable area to calculate the MSICP. If this pressure is exceeded, then from the results of the LOT/FIT, the formation will breakdown at the test TVD.

MSICP = BHP - (0.052 * Mud Wt (Pressure AMW from Max. Allowable area of General Section) * Test TVD)

The Daily Cost field is the sum of the costs for the current day entered on the Cost Data form.

The Supplemental AFE Total is the sum of all AFE Amounts that have a Supplemental AFE number assigned in the Daily Operations, Daily Cost section. Supplemental AFE data is recorded in Classic OpenWells and not from the Interactive Well Site.

The Cumulative Total field is the sum of all Costs the sum of all costs, entered on the Cost Data form, since the beginning of the Event.

The Daily Mud field is the sum of the Day Cost field on the Mud Data form.

The Cum Mud Cost field is the sum of the Daily Mud Cost fields for all previous Daily Operations reports.

The Last Est Cost, Est Date, Authorized Cost and Authorization Date are read-only fields. The data contained within these fields are populated by data entered in the General Tab of the Event Properties dialog.

When the SetEndDatesToFinalReport system setting is set to YES, the Event End Date is populated by the Daily Report's Date when the Final Report check box is checked. When the Final Report check box is unchecked the Event End date is set to NULL. For more information on this system setting see the EDM Administration Utility online help.

The Lithology field defines the lithology found at the current report depth. This picklist is based on entries in the Lithologies Tab of the Database Properties dialog.

The Formation field defines the formation found at the current report depth. This picklist is based on entries in the Strat Units Tab of the Project Properties dialog and filtered based on the current Wellbore (see the Formations Tab topic of the Wellbore Properties).

Units Picklist

The Unit Management System in the EDM™ database controls display units in EDT™ applications. Every numerical element in the EDM database has a storage measure (some known quantity in the physical world) associated with it such as feet, ft/sec, or °F.

In OpenWells® software, Active Viewing Units (or Display Units as they are sometimes referred to) are for presentation purposes only. Display units can changed at any time and do not affect the quality of the data.

Active Viewing Units for the OpenWells application are selected from the Unit picklist located at the top of each page.

Datum Selector

The reference point for depths changes over the life cycle of a Well, with changes in rigs and viewing data requirements.

The Datum Selector, located at the top of each page, allows users to change displayed the depth reference point (datum) on the fly.

Changing the depth reference point displays depths relative to the datum selected. This DOES NOT change the values in the database itself.

Data MUST be entered correctly in context to the selected datum reference point.

The following example shows how the viewing datum affects the data you see.
