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

TallyBook isa standalone DAQ unit designed for use by the oil and gasindustry in harsh environment and hazardous areas. TallyBook DAQ units have the capacity to providetransparent reporting on complex procedures such aswell interventions, with a view to making operationssafer and more efficient. Another key feature ofthe technology is that it offers post-operationalanalysis so that future processes can beoptimised.North Sea case studyTallyBook technology is currently beingused in a major project in the North Sea inwhich a leading operator is working on aseries of long-standing wells. The operatoris performing a number of chemical squeezeprocedures to regain production levels by cleaningup the well, and requires pinpoint data acquisition toensure the safety and efficiency of the work. The key parameters the operator wished to measure andrecord in the project were temperature, flow and density.Eztek developed the Zone 1 certified TallyBook to meet theclient’s criteria, as well as that of the EU’s ATEX directive onequipment that can operate in explosive atmospheres. The Zone 1 TallyBook was subsequently mounted on thepumping skid and attached to the required sensors. It becameapparent very quickly that the information delivered by the unit wasinvaluable on many levels. It not only allowed the water-chemical However, the addition of a 10.4-inch (264-mm) touch screen makesmix 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 fromthe best possible results immediately. graphical to digital display.

This removes the eREDrisk and cost associated with multiple slickline runs. An eRED action, such as opening or closing, is initiated onlywhen a specific well condition (known as a trigger) is detected.Upon successful completion of that action, the eRED can look foranother trigger, which in turn initiates the next action. Using a seriesof different trigger and action combinations, the eRED can be usedin complex well programmes, opening and closing as many times asrequired without any intervention. The next product in Red Spider’s Remote Open CloseTechnology line is the eRED-FB, which is the tubing-mounted Tubingversion of the eRED. It consists of a remotely actuated full-bore ballvalve that can be opened and closed multiple times, controlling flowthrough the tubing without the need for any umbilical control line. The use of eRED-FB completely eliminates the requirementfor any wireline runs during a completion placement operation,resulting in savings of between 32-38 hours and US$600,000 toover US$800,000 in subsea operations. Moreover, a mechanicaldownhole barrier is present at all times during operations, to be Production Packeractivated 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 wellson stream sooner and reducing the risk of exposure to bad weather. When closed, the eRED-FB provides a bi-directional downholebarrier, capable of holding up to 5,000 psi from above or below.When open, the large internal diameter maximises production orinjection and allows easy access to the well and equipment belowthe valve. Another Red Spider innovation, PowerBall, is a reservoirisolation barrier designed for reliability in debris-laden environments.It is intended to be run open, then subsequently closed during lowercompletion deployment and finally to be re-opened permanently byremote command for production or injection to commence. Remote opening of PowerBall happens with no pressure cycles, buton detecting a specific trigger, much in the same way as with eRED. Standard Lock 4.313 inThis in turn results in a much more flexible and efficient operation. Savings of up to 12 hours can be achieved thanks to the efficientactivation method of PowerBall. All the moving parts are placedbelow 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 eREDdebris can result in operational failure and costly shutdown time.By moving the mechanical parts of the ball mechanism below theclosed ball area of the tool, and as a result protecting them fromdebris, PowerBall offers maximum reliability in dirty environments.Avoiding remedial action caused by failure of a fluid loss device canresult in savings in the region of US$2 million. Tubing eRED and its sister applications are particularly suited fordeepwater and subsea work, where rig-time savings are mostvaluable. This makes the products especially suitable for deploymentin the North Sea, Brazil, Gulf of Mexico, West Africa, Australia andAsia-Pacific, where deepwater oil exploration is ramping up rapidly. n
