Welcome to the information pages
for NOV CTES’ award-winning Cerberus
for Well Intervention modeling software!
If you are a first-time visitor, we hope these
pages will prove a useful introduction and that you will consider
using Cerberus for your operations.
What is Cerberus
for Well Intervention?
Cerberus for Well Intervention consists of one or both of the following
modules:
Forces Modeling is used to analyze any operation involving
the deployment of tools into and out of a well on cable, pipe
or coiled tubing. By analyzing the cumulative forces acting downhole at
each stage of the job, the program is able to determine whether
the target depth can be reached, the desired tasks performed,
and the equipment safely returned to surface. The main
purpose is to determine the viability of a particular job design
and hence improve the safety and efficiency of operations. Its most
important feature is the ability to model conditions in deviated
and horizontal wellbores. Cerberus is
also the only commercial program able to model all three conveyance
methods in one package, making it invaluable for choosing the
best well entry technique in marginal conditions. Customers may
license the software to run one, two or all three methods, with
the price varying accordingly.
Wellbore Hydraulics
Modeling is used to calculate the pressures and flowrates during a wide variety of workover operations,
in order to optimize the job design and equipment selection.
Applications include circulating, acidizing,
cleaning, lifting, drilling, velocity strings and injection.
You can perform single snapshot calculations or simulate a complex sequence of events
using a Stage Table.
Other versions of Cerberus include Cerberus
for Coiled Tubing, Cerberus
for Wireline and Cerberus
for Drilling.

What applications can I model with Cerberus? As you can see from the list below, you can model just
about anything that involves running tools into a well.
- Open hole logging
- Cased hole logging
- Drilling, conventional
and underbalanced
- Workover operations
- Tubing Conveyed Perforating
(TCP)
- Pipe Conveyed Logging
(PCL)
- Slickline operations
- Fishing
|
- Snubbing (HWO)
- Coiled tubing operations
- Perforating on cable
- Running casing, liners
or tubing
- Running completions
- Plug and abandonment
(P&A)
- Flowlines and
Risers, servicing of

Note: Cerberus does not model operations
involving transients, such as jarring or perforating. |

Cerberus
as a Field Tool
- Is observed wellsite
data within expectations?
- What are the safety
limits in the event of contingencies?
- Set thresholds for
risk assumption by operator

Who is using Cerberus?
- Service companies,
for planning and executing jobs. Existing customers include
Baker Atlas (worldwide), Weatherford (worldwide), Halliburton
(worldwide), Schlumberger, and many others.
- Operators, for choosing
intervention methods for existing wells, and planning new wells
with future intervention requirements in mind. Existing customers
include BP, ExxonMobil, Shell, and
many others.
- Tool companies, to
justify selection of specific tools for a given application.
The software has been thoroughly field-proven to be highly accurate
and reliable, and has received several industry awards for engineering
excellence since its introduction in 1995, including Hart’s E&P
Meritorious Engineering Award for 2001.

What answers does Cerberus provide? Many
of the calculations are similar for all three conveyance methods,
but some are specific, so we have divided the information into
categories. Click on the following options to see how Cerberus presents
results for each.
Wireline || Jointed
Pipe || Coiled Tubing
