IoT-based well surveillance solution

January 2018 Fieldbus & Industrial Networking

Siemens has announced a scalable, end-to-end IoT solution, designed to help oil and gas companies optimise production and reduce costs through connected systems, automation, and analytics at the edge. This innovative solution offers companies across the oil and gas industry a cost-efficient solution to link distributed assets into an integrated network with minimal effort, while simultaneously providing a high level of automation.

Declining revenues demand new approaches

In a sector beleaguered by falling prices, Siemens IoT Well Surveillance will allow energy companies to acquire the cost benefits of digitisation. Oil and gas prices have dropped by 50 percent since 2014 and companies are looking to technology for the business transformation that will increase efficiency and optimise operations. Oilfield facilities and assets are typically a significant distance apart and often only partially integrated into automation systems. This makes data capture for central storage and analysis difficult and limits operational visibility. Siemens IoT Well Surveillance lets companies connect and integrate data from previously unconnected assets in a cost-efficient manner, enabling comprehensive condition monitoring, predictive maintenance and reduced facility downtime.

Smart data, condition monitoring and analytics at the edge

Siemens IoT Well Surveillance addresses field operation and oilfield artificial lift control. The solution uses existing sensors and Siemens Simocode motor management system as key inputs for edge data analytics. The edge computing device, an Intel-powered Siemens Nanobox, performs advanced analytics and soft sensing on this data, calculating pump conditions from it, triggering alerts and optimising production. Performing these calculations at the pump enables independent operation on the well. For further processing and field analytics the information is sent to a central system such as scada or an IoT platform. Dynagraph and alert functions with video integration are available for well site personnel via a fully interactive web portal.

Seamless connection between production facility and applications

Overall benefits of Siemens IoT Well Surveillance include increased asset awareness, operational efficiency, and increased revenue from production optimisation. “Siemens IoT Well Surveillance optimises oil production and works with the utmost energy efficiency,” says Uwe Tröger, Siemens global head of oil and gas onshore and senior executive VP of the Process Industries and Drives (PD) and the Digital Factory (DF) divisions in the Middle East. “This enables costs to be driven down in an industry undertaking enormous efforts to ensure continued profitability in the face of low oil prices. By using digitalisation and innovative technologies already successful in other industries, it is also possible to improve both economy and reliability.”

Intel’s technology collaboration

Intel collaborated with Siemens in the development of Siemens IoT Well Surveillance. Both Intel technologies and hardware are featured in the solution, including an Intel Atom processor-powered Siemens Nanobox gateway and an Intel-based wireless access point. The Intel Core i5 processor-powered ruggedised tablet is used for onsite visualisation of up to six months of data and for data capture at the well. Intel also collaborated on the edge software. “Siemens’ innovative IoT solution for artificial lift monitoring, analytics and control, based on scalable Intel IoT technology, demonstrates the value of edge analytics and soft sensing for well optimisation and control, while appreciably lowering the total cost of ownership,” says Christine Boles, general manager of the Industrial & Energy Solutions division in Intel’s Internet of Things group. “Together, Intel and Siemens are helping transform the world of oil field automation and enabling companies to succeed in a challenging market.”

OMV pilot deployment

OMV, a Vienna-based integrated oil and gas company, has been piloting the Siemens IoT Well Surveillance solution at an OMV oilfield since April 2017. An operator of several thousand beam pump stripper wells, OMV is highly encouraged by the early pilot results which have enabled production optimisation, early production loss identification and deferment, maintenance optimisation and field personnel relief. “The Siemens solution enables complete asset awareness at reasonable cost for wells with low production, such as stripper wells,” says OMV Saša Blažekovi, team leader, production support.
