Offshore Technology Conference Preview
access to replace individual modules, reducing the critical path of the operation and the time to repair from days to hours and from hours to minutes.
When parts or modules break down, that specific module can be replaced without interrupting other systems of the top drive. The downtime of overhauls and annual load path inspections is reduced, which can usually only be conducted offline or during a rig move. The modular design and the number of quick connector devices also reduces the assembly time, which leads to reduced delivery time of a complete MH MDDM 1000. In addition to its modularity, the innovative design of the MH MDDM 1000 machine provides maximum up- time and performance, and enhanced safety and efficiency while drilling offshore.
FlowCAT marks the introduction of a more controllable and predictable alternative to an ambient valve or storm choke, minimises deferred production and increases well safety.
MPM meter will automatically switch up to five times per second between the multiphase and wet-gas modes, bridging a gap previously not covered by multiphase meters. The MPM Subsea MPM has been qualified through the stringent Det Norske Veritas (DNV) RP-203 qualification process to an impressive 15,000psi working pressure and a remarkable 480°F working temperature. The MPM meter has also been designed for 11,500ft water depth.

Self-configuring Multiphase Meter
Multiphase meters (MPMs) employ tomographic technology to significantly improve measurement accuracy and measurement range for MPMs for topside and subsea applications. The self-calibrating feature implemented in the MPM meter is a step change from conventional multiphase meters. This new feature is achieved through implementing salinity measurement functionality in combination with the in situ fluid property verification.
FlowCAT™ Wireless Safety Valve System
Surface-controlled sub-surface safety valves (SCSSVs) are prone to failure due to plugging or leaks in the hydraulic control line. The common remedial solution involves installing an SSCSV, such as a storm choke. These SSCSVs are directly influenced by changing well conditions, such as high flow rates, low pressure or water slugs, and thus are notoriously unpredictable in operation. Additionally, they are not controllable from the surface and not fail-safe, which is undesirable from a well control and safety standpoint.
Developed with the support of Petrowell Ltd, FlowCAT is a new wireless-controlled safety valve system that can be retro-fitted into a well using conventional slickline intervention equipment and procedures. Being controllable from the surface and of a fail-safe closed design, this offers both functional and safety advantages over existing SSCSV solutions. The valve system also offers a retro-fittable solution where no hydraulic control line is installed, and, where a capillary string may need to be installed for foam injection purposes, it provides an opportunity to free up the hydraulic control line.

GeoTap® Intrusion Detection System
Until now, the acquisition of formation fluid samples was only possible on wireline. The new InSite GeoTap® intrusion detection system (IDS) sensor from Sperry Drilling services has revolutionised the industry by for the first time enabling reservoir fluid samples to be recovered with logging-while-drilling (LWD) technology. The sensor delivers timely downhole capture, surface recovery and identification of multiple samples of formation fluids with minimal contamination.
The MPM works equally well for multiphase and wet-gas applications, for gas void fractions of 0–100% and water cut of 0–100%. The industry-sponsored 3D Broadband® technology is employed to accurately and rapidly determine how the liquid and gas are distributed throughout the pipe, while at the same time determining precise flow rates of oil, gas and water. For slugging flow regimes, the
EXPLORATION & PRODUCTION – VOLUME 8 ISSUE 1
Eliminating the flat time associated with wireline sampling, the GeoTap IDS sensor can acquire multiple fluid samples within hours, rather than days, of drilling the formation. However, time saving is only one of the benefits it delivers. With the addition of the GeoTap IDS sensor, Halliburton now provides true formation testing while drilling capabilities for optimising wellbore placement to achieve maximum production over the life of the reservoir.
In high-cost environments, such as deepwater exploration wells, there is significant value in eliminating trips for wireline sampling tools. Besides, when samples are taken while drilling, formation contamination from drilling fluids is much less, so extended pump-out
