Tests
in the
pipeline
ShawCor’s SSV offers a means of
predicting pipeline performance,
which will be critical as operations
move into deeper and deeper waters


A
             s the world’s production frontier moves into ever-deeper
             water, the problem of predicting how subsea production
             systems will perform over time and under pressure
             comes very much to the fore. A key factor is thermal
insulation – working under great pressure, in an ambient temperature
near freezing, how well will pipe, valves and other subsea
production structures maintain their internal fluid temperatures? If
production has to be stopped for any reason, how long have you got
before the internal temperature of your system falls below a critical
point? Until now, theoretical models, limited experience elsewhere,
a large element of over-specification and a pinch of good luck
have been the only way to specify pipe and valves for deepwater
completions.
    That obviously is not good enough for the long term, so ShawCor
has built the world’s largest and most capable vessel for simulating
offshore service conditions up 3,000 metres water depth (300 bar)
and with fluid temperatures up to 180°C – the Shawcor Simulated
Service Vessel (SSV)
    The SSV is an 82 tonne pressure vessel located in the ShawCor
Subsea Test Facility in Toronto, Canada, in which the sample being
tested is loaded on to a carriage and then inserted into a pressure
cylinder. The test sample, which can be rigid or flexible pipe,              Once thermal equilibrium is established, the SSV is pressurised and

Eztek measures up

W
                 ith a number of its clients in the oil industry
                 posing this question, Eztek embarked on the
                 development of the TallyBook range of data
                 acquisition (DAQ) technology. TallyBook is
a standalone DAQ unit designed for use by the oil and gas
industry in harsh environment and hazardous areas.
   TallyBook DAQ units have the capacity to provide
transparent reporting on complex procedures such as
well interventions, with a view to making operations
safer and more efficient. Another key feature of
the technology is that it offers post-operational
analysis so that future processes can be
optimised.

North Sea case study
TallyBook technology is currently being
used in a major project in the North Sea in
which a leading operator is working on a
series of long-standing wells. The operator
is performing a number of chemical squeeze
procedures to regain production levels by cleaning
up the well, and requires pinpoint data acquisition to
ensure the safety and efficiency of the work.
    The key parameters the operator wished to measure and
record in the project were temperature, flow and density.
Eztek developed the Zone 1 certified TallyBook to meet the
client’s criteria, as well as that of the EU’s ATEX directive on
equipment that can operate in explosive atmospheres.
    The Zone 1 TallyBook was subsequently mounted on the
pumping skid and attached to the required sensors. It became
apparent very quickly that the information delivered by the unit was
invaluable on many levels. It not only allowed the water-chemical            However, the addition of a 10.4-inch (264-mm) touch screen makes

    Any application where a wireline lock and plug are used can be
replaced by an eRED valve, thus achieving exactly the same results
without the need for repeated intervention jobs. This removes the                           eRED
risk and cost associated with multiple slickline runs.
    An eRED action, such as opening or closing, is initiated only
when a specific well condition (known as a trigger) is detected.
Upon successful completion of that action, the eRED can look for
another trigger, which in turn initiates the next action. Using a series
of different trigger and action combinations, the eRED can be used
in complex well programmes, opening and closing as many times as
required without any intervention.
    The next product in Red Spider’s Remote Open Close
Technology line is the eRED-FB, which is the tubing-mounted                                 Tubing
version of the eRED. It consists of a remotely actuated full-bore ball
valve that can be opened and closed multiple times, controlling flow
through the tubing without the need for any umbilical control line.
    The use of eRED-FB completely eliminates the requirement
for any wireline runs during a completion placement operation,
resulting in savings of between 32-38 hours and US$600,000 to
over US$800,000 in subsea operations. Moreover, a mechanical
downhole barrier is present at all times during operations, to be
                                                                                            Production Packer
activated upon request and to take control of the well.
    Eliminating the requirement to deploy traditional control line-
operated equipment speeds up the completion process, bringing wells
on stream sooner and reducing the risk of exposure to bad weather.
    When closed, the eRED-FB provides a bi-directional downhole
barrier, capable of holding up to 5,000 psi from above or below.
When open, the large internal diameter maximises production or
injection and allows easy access to the well and equipment below
the valve. Another Red Spider innovation, PowerBall, is a reservoir
isolation barrier designed for reliability in debris-laden environments.
It is intended to be run open, then subsequently closed during lower
completion deployment and finally to be re-opened permanently by
remote command for production or injection to commence.
    Remote opening of PowerBall happens with no pressure cycles, but
on detecting a specific trigger, much in the same way as with eRED.
                                                                                            Standard Lock 4.313 in
This in turn results in a much more flexible and efficient operation.
    Savings of up to 12 hours can be achieved thanks to the efficient
activation method of PowerBall. All the moving parts are placed
below the closed ball, where they are not exposed to debris,
improving the reliability of the tool.
    Drilling technologies that are exposed to large amounts of
                                                                                            eRED
debris can result in operational failure and costly shutdown time.
By moving the mechanical parts of the ball mechanism below the
closed ball area of the tool, and as a result protecting them from
debris, PowerBall offers maximum reliability in dirty environments.
Avoiding remedial action caused by failure of a fluid loss device can
result in savings in the region of US$2 million.                                            Tubing
    eRED and its sister applications are particularly suited for
deepwater and subsea work, where rig-time savings are most
valuable. This makes the products especially suitable for deployment
in the North Sea, Brazil, Gulf of Mexico, West Africa, Australia and
Asia-Pacific, where deepwater oil exploration is ramping up rapidly. n

A key factor is thermal insulation – working under great pressure, in an ambient temperature near freezing, how well will pipe, valves and other subsea production structures maintain their internal fluid temperatures? If production has to be stopped for any reason, how long have you got before the internal temperature of your system falls below a critical point? Until now, theoretical models, limited experience elsewhere, a large element of over-specification and a pinch of good luck have been the only way to specify pipe and valves for deepwater completions. That obviously is not good enough for the long term, so ShawCor has built the world’s largest and most capable vessel for simulating offshore service conditions up 3,000 metres water depth (300 bar) and with fluid temperatures up to 180°C – the Shawcor Simulated Service Vessel (SSV) The SSV is an 82 tonne pressure vessel located in the ShawCor Subsea Test Facility in Toronto, Canada, in which the sample being tested is loaded on to a carriage and then inserted into a pressure cylinder. The test sample, which can be rigid or flexible pipe, Once thermal equilibrium is established, the SSV is pressurised and valves, seals, joints, flanges, and even custom fabricated parts, is held at the required pressure for the duration of the test. Pressure is then heated to the desired test temperature, while being subjected to increased in steps to assess the immediate and long-term response external pressure to simulate its planned operating environment. The of the insulation properties to changes in pressure at a specific SSV can test multi-layer or injection-moulded insulation coating operating temperature, and so capture the reaction of the system systems, and can take pipe up to an external diameter (including to pressure changes.

  • 7. August 2012 InnovOil by vNewsBase page 7 Eztek measures up “If you can’t measure it, how can you manage it?” W ith a number of its clients in the oil industry posing this question, Eztek embarked on the development of the TallyBook range of data acquisition (DAQ) technology. TallyBook is a standalone DAQ unit designed for use by the oil and gas industry in harsh environment and hazardous areas. TallyBook DAQ units have the capacity to provide transparent reporting on complex procedures such as well interventions, with a view to making operations safer and more efficient. Another key feature of the technology is that it offers post-operational analysis so that future processes can be optimised. North Sea case study TallyBook technology is currently being used in a major project in the North Sea in which a leading operator is working on a series of long-standing wells. The operator is performing a number of chemical squeeze procedures to regain production levels by cleaning up the well, and requires pinpoint data acquisition to ensure the safety and efficiency of the work. The key parameters the operator wished to measure and record in the project were temperature, flow and density. Eztek developed the Zone 1 certified TallyBook to meet the client’s criteria, as well as that of the EU’s ATEX directive on equipment that can operate in explosive atmospheres. The Zone 1 TallyBook was subsequently mounted on the pumping skid and attached to the required sensors. It became apparent very quickly that the information delivered by the unit was invaluable on many levels. It not only allowed the water-chemical However, the addition of a 10.4-inch (264-mm) touch screen makes mix to be read in real time, but could also be adjusted, thus giving it versatile and simple to use as the operator can swiftly switch from the best possible results immediately. graphical to digital display.

August 2012 InnovOil by vNewsBase page 9 Contact: Red Spider Technology Tubing Hanger Peregrine Road, Westhill, Aberdeenshire, AB32 6JL Tel: +44 1224 275000 www.redspiders.com Standard Lock 4.875 in Any application where a wireline lock and plug are used can be replaced by an eRED valve, thus achieving exactly the same results without the need for repeated intervention jobs. This removes the eRED risk and cost associated with multiple slickline runs. An eRED action, such as opening or closing, is initiated only when a specific well condition (known as a trigger) is detected. Upon successful completion of that action, the eRED can look for another trigger, which in turn initiates the next action. Using a series of different trigger and action combinations, the eRED can be used in complex well programmes, opening and closing as many times as required without any intervention. The next product in Red Spider’s Remote Open Close Technology line is the eRED-FB, which is the tubing-mounted Tubing version of the eRED. It consists of a remotely actuated full-bore ball valve that can be opened and closed multiple times, controlling flow through the tubing without the need for any umbilical control line. The use of eRED-FB completely eliminates the requirement for any wireline runs during a completion placement operation, resulting in savings of between 32-38 hours and US$600,000 to over US$800,000 in subsea operations. Moreover, a mechanical downhole barrier is present at all times during operations, to be Production Packer activated upon request and to take control of the well. Eliminating the requirement to deploy traditional control line- operated equipment speeds up the completion process, bringing wells on stream sooner and reducing the risk of exposure to bad weather. When closed, the eRED-FB provides a bi-directional downhole barrier, capable of holding up to 5,000 psi from above or below. When open, the large internal diameter maximises production or injection and allows easy access to the well and equipment below the valve. Another Red Spider innovation, PowerBall, is a reservoir isolation barrier designed for reliability in debris-laden environments. It is intended to be run open, then subsequently closed during lower completion deployment and finally to be re-opened permanently by remote command for production or injection to commence. Remote opening of PowerBall happens with no pressure cycles, but on detecting a specific trigger, much in the same way as with eRED. Standard Lock 4.313 in This in turn results in a much more flexible and efficient operation. Savings of up to 12 hours can be achieved thanks to the efficient activation method of PowerBall. All the moving parts are placed below the closed ball, where they are not exposed to debris, improving the reliability of the tool. Drilling technologies that are exposed to large amounts of eRED debris can result in operational failure and costly shutdown time. By moving the mechanical parts of the ball mechanism below the closed ball area of the tool, and as a result protecting them from debris, PowerBall offers maximum reliability in dirty environments. Avoiding remedial action caused by failure of a fluid loss device can result in savings in the region of US$2 million. Tubing eRED and its sister applications are particularly suited for deepwater and subsea work, where rig-time savings are most valuable. This makes the products especially suitable for deployment in the North Sea, Brazil, Gulf of Mexico, West Africa, Australia and Asia-Pacific, where deepwater oil exploration is ramping up rapidly. n
