OTC ’14: News roundup from the Offshore Technology Conference


HOUSTON -- Kicking off this week's international upstream event was news involving China’s shale gas development. Representatives from GE Power & Water’s Distributed Power Business and China’s HongHua Group, a leading Chinese drill rig manufacturer, signed a three-year agreement to supply GE’s Waukesha VHP engines. The Waukesa gas engines will be used with HongHau generators to power new drilling rigs in operating in China and Asia.

Gas over diesel. The Waukesha gas engines offer high reliability, especially in the tough exploration and production (E&P) environment. More importantly, these engines can successfully burn any gaseous fuel, from 950 Btu to 2,600 Btu, including  field gas, LNG, CNG, propane, biofuel and coke oven gas. Switching from diesel to gas can provide drilling rig operators the opportunity to reduce energy cost by 75%. Typical drilling rigs use three diesel engines. Converting to gas engines will also reduce greenhouse gas emissions for drilling operations , and NOx emissions scan be reduced by 95% with gas engine.

China’s shale gas vision. Shale gas is at a turning point in China. It is estimated that by 2017 total E&P will approach 10 Bcm. Zhang Mi, chairmaem and CEO of Honghua Group expressed great optimism for shale gas. Honghua is the second largest rig manufacturer of China. According to Zhang, over 100 drilling rigs will be drilling for shale gas in China by 2015. Zhang viewed China’s shale gas on the same level of North America. By 2020, E&P for shale gas will approach 1 Tcm. The GE-Honghua agreement is positive step for China to leverage the nation’s gas resources.  

More gas news. Emerson Process Management released a new version of its Daniel process acquisition controller at the 2014 OTC. New features in DanPac Version v3.0 build on the system’s ability to reduce measurement uncertainty, facilitate remote monitoring and control high precision O&G custody transfer and fiscal metering systems.

The CalPac metering software suite is a new feature, which uses a number of applications developed to automate flow measurement calculations and data processing, including gas and liquid calculations, measurement uncertainty and meter factor trending.  Integrated historical system performance and process trending capabilities enable operators and management to monitor the metering system.  Operators can identify potential meter problems before they can adversely impact system performance. The applications allow automated online validation of metering data in accordance with industry standards, including API, ISO and AGA, to minimize errors and satisfy audit trail requirements.

The new release also includes a powerful enterprise class web-based reporting application to enhance accessibility and audit traceability. The platform provides secure and encrypted PDF reporting capabilities. These eliminate the possibility of data manipulation and safeguard the integrity of custody transfer and fiscal metering transactions.  Users can also customize reporting content and layout to fit their needs. In addition, DanPac easily integrates with a broad variety of DCS hosts and SCADA systems to provide metering information.

The DanPac solution replaces a long-standing industry approach that did not provide the needed reliability, ease of serviceability, robustness, and cost savings. The industry relied largely on one-off, custom-built control solutions that were expensive to structure and support, making training and service costly, limited, and slow. With the DanPac solution, users will benefit not only from a standardized control system with integrated engineering and operations environment, but also from a single point of responsibility for global, consistent and rapid support services.

The DanPac solution is available in four flexible system configurations to ensure a cost-effective solution regardless of the size of the metering operation. The architecture of DanPac v3.0 includes a logic controller and the Daniel S600+ flow computers. It is designed to be redundant for high reliability, which is particularly valuable on offshore and remote locations.
