How the Change in Bias Weld Derating in Cerberus String Editor Affects Your Models

 
The purpose of this post is to clarify the reason for the change in the default bias-weld derating from 80% to 50% in Cerberus v12.0 String Editor, and to let you know that further changes will be forthcoming in future builds of Cerberus v12.0. 

A new bias weld model  – available in Cerberus v12.0 – was obtained by testing many bias welds on a material and deriving the model parameters that provide the most reliable results for bias weld fatigue.  Currently this bias-weld model has only been completed for QT-1300; however, we expect to release new materials that support this model in the near future.  

The change to the default derating was made due to a high level of concern in the industry regarding bias weld failures.  While many of these failures are corrosion related, there is still a significant percentage of these failures that are not related to corrosion.  Testing has been done by some of the manufacturers that has indicated that 80% is too aggressive for high pressures and higher-strength materials.  80% might be appropriate for low-grade pipe with low pressures, but pipe that is 100-grade and above likely needs a more conservative derating.   

Since a majority of the jobs now require higher pressures and higher-strength pipe, we no longer believe 80% is an appropriate default value.  While 50% is too conservative in some cases, it was selected because it provides a safe default value in all cases.*  We are continuing to acquire testing results to help identify a default value that will be appropriate for a wider array of scenarios.  We will update Cerberus v12.0 with the new defaults when this data is available.  

* The string’s derating value may be manually changed in Cerberus to adjust for material type and working conditions.  

* No derating value is needed if you are using a string with a material that supports an Achilles 5 fatigue model with the newly available bias weld model.  In fact, using the Achilles 5 bias weld model is highly preferable to using the default bias weld derating.  

If you would like to discuss bias-weld derating in further detail, please contact the CTES Support Team: 936.777.6200 or CTESSupport@nov.com. 

 

Extensive New Features Mark the Release of Cerberus™ Version 12.0 Software

 
NOV CTES is pleased to announce the release of Cerberus v12.0 modeling software! 

Following are just a few of the enhancements included in the new Cerberus v12.0:  

  • The String Design Wizard now delivers a more user-friendly string-design interface. Users now have the potential to design strings that are more suited for use in field operations when compared to previous versions of Cerberus.  
  • The new Friction Coefficient Analysis wizard is used to find the wellbore’s friction factors for a given field dataset so that the predicted surface weights best fit the data.  Such obtained friction factors usually are called “apparent” friction factors. 
  • Orpheus’ new Real Time Force Monitor is able to acquire data from OrionNET™ data acquisition software and to calculate weight on bit, stress and limits in real time.  The Force Monitor also includes utilities to provide real time information to optimize plug milling and to analyze a plug milling operation post-job. 
  • A new “length” field has been added to the Nipples panel in Well Editor to provide the user better control over potentially significant fluid-flow effects when running through restrictions defined in Well Editor. 
  • Cerberus now offers SharePoint™ integration. Users with existing SharePoint access may print a CTES PDF to their SharePoint server/location. Users with SharePoint expertise can import/export items and projects from within Cerberus to SharePoint.

NOV CTES Unveils New, Streamlined Features with OrionNET™ Version 2.5 Software

 

NOV CTES is pleased to announce the release of OrionNET v2.5 software! Following are just a few of the new features/capabilities.   

OrionNET’s applications are now touchscreen-friendly!     

The version 2.5 OrionNET user interface is redesigned to better differentiate between the three types of functionalities: Acquisition, Viewer, and Reports.     

Viewer:  

  • OrionNET’s new simulators imitate the functioning of Orion™ hardware, so that users can better understand the interaction of the OrionNET software and the Orion hardware. An excellent training tool, the simulators provide access to all features of OrionNET, including configuration, calibration, and diagnostics. Note that the simulators have no interaction with the actual Orion hardware.    
  • The data-viewing area is maximized, and users can quickly insert comments that have been predefined.  
  • A new Acquisition menu is now available in the Viewer to make accessing Acquisition functions simpler. 
  • Users can now undo/redo steps/actions within the Viewer.      

Reports:  

  • Generate reports from the Viewer with a single click without launching the Reports application.   
  • Create customized reports to meet your company’s specific reporting needs. Now available is the ability to print multiple ranges of OrionNET data.    
  • Divide large Reports files into smaller segments for emailing and for restoring to a different computer.    
  • Merge multiple OrionNET databases using only one step in OrionNET Reports.   

Take advantage of the new OrionNET features today! Contact the NOV CTES Business Development team for complete details or for a price quote.: +1 936 777 6200; CTESSales@NOV.com. 

 

Experience Next Generation Wellsite Data Acquisition with the Orion™ V DAS from NOV CTES

 

NOV CTES is pleased to announce the availability of the Orion V Data Acquisition System – the next generation in the line of NOV CTES Data Acquisition System hardware.

Here are just a few of the features that make the Orion V a leader in the arena of wellsite data acquisition:

  • Easy-to-view onboard diagnostics: Indicator lights visible through the Orion V's front viewing pane allow users to quickly assess the unit's operational status without opening the NEMA 4X enclosure.
    • Both the OrionNET™ data acquisition software and ROVer™ (Remote Orion Viewer) HMI receive and display the Orion V diagnostic messages.     
     
  • Small footprint. While more powerful, the Orion V has a twenty-five percent reduction in size compared to prior systems.
  • The Orion V Electronic Memory Unit (EMU) is now housed inside the controller and has been expanded to 10 times the previous capacity.
  • The Orion V seamlessly interfaces with the industry's leading modeling software, Cerberus from NOV CTES.
