NOV CTES NEWS
The CTES Orion™ V DAS for Hazardous Areas is Now Available!
the release of the ATEX hazardous-area-certified Orion V Data
Acquisition System (DAS) . . .
Orion V DAS for Hazardous Areas retains many of the standard Orion V features,
while providing hazardous-area-compliant enhancements:
and maintains an accurate record of all monitored parameters during a coiled
tubing (CT), pumping, acidizing, or hydraulic workover operation (HOW).
health indicators are visible without opening the door: digital, quadrature and
serial I/O module I/O status, and communication indicators.
address and serial number are visible on the enclosure.
Memory Unit (EMU):
job-log storage capacity > 2,400 hrs.
in EMU files: Channel configuration changes, unit description, and serial
function internal to PLC
user intervention required
Orion system is modular and can be configured to meet user requirements that
are ATEX certified.
scaling applied on controller/brain module results in increased data integrity
between acquisition PCs as well as the EMU.
to 48 channels are available for I/O, including RS485 input with IS isolators
(2 streams per module; 1 per isolator).
configurable digital output (requiring flameproof protection) – up to 4 relay
or 12V outputs; 2 required for ESS option.
available options include wireless data transmission and the CTES Emergency
Stop System (ESS).

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

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”
- 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

NOV CTES Unveils New, Streamlined Features with OrionNET™ Version 2.5 Software
Announcing . . . the release of OrionNET v2.5 software! Following
are just a few of the new features/capabilities.
applications are now touchscreen-friendly!
version 2.5 OrionNET user interface is redesigned to better differentiate
between the three types of functionalities: Acquisition, Viewer, and Reports.
- 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
- A new Acquisition
menu is now available in the Viewer to make accessing Acquisition functions
- Users can now
undo/redo steps/actions within the Viewer.
- 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
- Merge multiple
OrionNET databases using only one step in OrionNET Reports.

Experience Next Generation Wellsite Data Acquisition with the Orion V DAS from NOV CTES
The Orion V Data Acquisition System – the next generation in the line of NOV CTES Data Acquisition System hardware – is now available.
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.
