Halliburton has announced the availability of its HCS AdvantageOne offshore cementing system, which it says represents the next-generation of cementing and well-control pumping system. It is specifically designed to address the complexities of deepwater and ultra-deepwater cementing with the versatility for use in shallow waters.
The company says that the cementing system has been optimized for an optional 20,000 psi manifold to allow work in water depths that exceed the pressure limit of conventional equipment. This new 20,000 psi manifold increases well-control ability and can be used for pressure testing deepwater subsea BOP stacks.
At the heart of the HCS AdvantageOne offshore cementing system is the 25-bbl, three-compartment configurable RCM IIIr mixing system and an integrated six-pump liquid additive system with dynamic inventory management. The liquid additive automated metering and pumping unit enables access to an array of additives required to tailor slurry systems for the demands of offshore wells, including ultra-deepwater wells.
In addition, it facilitates logistical efficiency with the use of totes for liquid materials storage, rather than further limiting the available bulk storage on an offshore vessel for dry goods. The pumps are a completely new stainless steel design providing instantaneous responsiveness for adjusting fluid-flow rates delivering advanced blend accuracy. Uniquely, the mixing system, liquid additive system, and the 80-ft3 Steady Flow separator (dispenses dry cement) are all controlled by the same PLC (programmable logic controller) system for enhanced precision of the mixing proportions of dry materials, mix water, and fluid additives, matching the actual slurry to the ideal job requirement design.
