Offshore Technology Conference, Proceedings | Year: 2012
A discussion covers the measurement of CO2 emissions from gas flaring activities n the oil and gas industry; regulatory requirements for monitoring and reporting flare gas emissions; challenges faced by industry in implementing accurate measurement schemes; technologies and best practice used by oil and gas operators; monitoring and reporting processes; uncertainty associated with hot-tapping; importance of installing meters; and automated reporting documents. This is an abstract of a paper presented at the Offshore Technology Conference 2012 (Houston, TX 4/30/2012-5/3/2012).

The future of multiphase flow measurement is being driven by the need for cheaper, lighter, and more flexible production systems. Multiphase meters give continuous measurements, allowing better reservoir management and quicker response to water breakthrough and similar events. Multiphase flowmeters consist of a number of sensors connected to a processing unit that derives the flow rates of each fluid. As subsea interventions are significantly expensive, it is highly desirable that a multiphase meter can function for long periods of time before maintenance. In this direction, NEL was involved with the Research Partnership to Secure Energy for America (RPSEA) on a research project in which sand erosion was assessed for different multi-phase meter configurations. Test and computational fluid dynamics (CFD) work carried out at NEL in conjunction with a major meter manufacturer has shown that most conventional multi-phase meters need to correct for the effect of liquid viscosity in heavy oil applications.

Elaine Maslin discusses different aspects of flow measurement as used in the offsore oil and gas industry. Metering technologies and the requirements advance, as the oil and gas industry moves into harsher, more complex environments. Building, testing and calibrating wet gas and multiphase meters, creating meters for high-viscosity oils, and using data available through new generation devices for diagnostics and more intelligent calibration regimes, are some key themes for the flow measurement sector.

The article explains how extraction of the heavier crudes is growing rapidly, leading to an increasing need for flow measurement of high viscosity hydrocarbons. Innovative methods of recovery, transportation and measurements are essential to fully exploit the world's heavy oil reserves and to bring the benefits of a diverse energy supply. In terms of accurately measuring heavy oil, a variety of issues have been identified and reported with respect to some of the measurement technologies currently being applied to viscous fluids. The Coriolis mass flow meter and the ultrasonic flow meter are both relatively modern flow measurement technologies and continue to capture increasing market share as operators gain confidence in their performance. The test data now appears to display a notable trend with decreasing pipe Reynolds number. Coriolis meters also offer significant flow meter diagnostic capabilities.

The factory will have an annual capacity to manufacture hydrogen refueling stations sufficient to support 200,000 new Fuel Cell Electric Vehicles (FCEV) annually. With a total investment of NOK ~85 million (US$10.25 milion), including contingency, NEL intends to convert the facility into a state-of-the-art volume production facility for refueling stations based on lean manufacturing principles. When ramp-up and plant optimization is complete, the facility will have a name-plate production capacity of up to 300 refueling stations per year. Leading global car manufacturers are introducing FCEVs into more markets and plan for growth in volumes towards 2020 and beyond. This requires an adequate capacity for manufacturing of hydrogen refueling stations to support a wider roll-out of hydrogen infrastructure. The new production facility in Denmark will be prepared for the next generation refueling technology (H2Station) that will offer advances in areas such as increased refueling capacity and performance, reduced footprint and potential for significant cost reductions. The new H2Station technology has been designed for lean volume manufacturing which is essential to achieve sufficient scale benefits. In contrast to many others, NEL is approaching the refueling station business in a mature and professional way. Even if a refueling station is relatively complex, it is just another piece of equipment that has to have a small footprint, high uptime, and low cost of ownership. This can only be achieved through modular design, standardization and volume production based on lean manufacturing principles – this is how we will add value to our customers. Since 2011, H2 Logic has gained experience with volume manufacturing of hydrogen refueling stations, however, at a smaller scale. This has resulted in a market share in Europe of more than 30%. H2 Logic will start to relocate to the new facility in the second half of 2016, and will complete the rebuild and relocation during 2017. The company has also secured 9000 m2 of expansion area adjacent to the Herning facility.
