Mud Data

The Mud Data form records information on muds in a single location, reducing the need to navigate around the application to enter data related to wellbore muds. This form allows users to add, review, modify and delete mud inventory, checks, geology, carbide lag chromatography, gas peak, mud gas and lithology intervals on a daily basis.

OpenWells ships two versions of the Mud form, click on one of the links below to access information on how to enter Mud data.

The Reset Item's Inventory Entered Today button allows the user zero out the Used, Received, Returned and Adjusted product usage values for the selected row. This button can be used to indicate that there were no transactions for the mud today. This is an alternative to deleting the mud row, as deleting the row deletes all transactions recorded against the mud over the entire Event.

Cost data entered in the Mud Inventory spreadsheet can be updated on the Daily Cost form by selecting the Update Daily Costs button. This adds cost items for each unique Class, Code and Subcode used in the Mud Inventory.

The Class, Code and Subcode for the Mud Inventory item is controlled by the UpdateCodesDailyMudCosts System Setting. If this setting is not configured the mud will appear in the Daily Cost form with the Description (Mud Costs).

For more information on this system setting see the Shipped Parameters topic in the EDM Administration Utility.

The Daily Mud Cost is calculated as the sum of the Cost column in the Mud Inventory spreadsheet.

The Cum Mud Cost is calculated as the sum of all Daily Mud Costs up to and including today's.

The Cost column indications the total cost for the mud product and is calculated as follows:

Cost = Price Per Unit * Used

The Quantity Start column always indicates the inventory on hand at the beginning of the reporting day. OpenWells retrieves this value from the Quantity End column of the previous day's mud inventory.

Use the Adjusted column to enter any extra product units not included in the Quantity Start

Note: OpenWells can handle both positive and negative numeric values in the Adjusted column. However you MUST indicate that OpenWells should subtract a number by placing a minus sign (-) in front of it. If you fail to do this, OpenWells assumes that the adjustment is a positive one and adds the numeric value to the current figure in the Quantity End column.

The Quantity End column automatically calculates the amount of product on hand and is calculated as follows:

Quantity End = Quantity Start + Received + Adjusted - Returned - Used

Note: When recording initial shipments, the Quantity End column will contain the same values as the Received column.

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

The Description field contains a short phrase describing the report’s purpose.

The Daily Geology 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 Geology Report.

Note: If the Locked Data button in 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 Last Casing comes from the Hole Sections section of the Daily Operations report with the same report date. This information comes from the following fields in the Last Casing/Liner area for current hole sections:

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

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

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.

Click the Details link, on the Intervals spreadsheet, to enter detailed information on the interval and cutting's 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.
