Oil & gas
Mine. The mine is located in the jurisdiction of 277 industrial gas wells with a daily production capacity of 20 million cubic meters. Specifically, the customer wanted to improve remote monitoring of all its key gas wells with a better use of data. A key feature of this digital transformation would be the installation of an internet protocol (IP) camera at each site, giving regular images of the well head. But how could this be achieved securely? Ovarro’s solution was to install a total of 70 solar-powered TBox RTUs within a supervisory control and data acquisition (SCADA) system. The RTUs have the
responsibility of capturing and transmitting an image snapshot each hour, or upon an alarm. In the case of a communications outage, the historian capabilities of the RTU can store months-worth of historical data on pressure, process shut-off valve position and more. This can be backed-up and transmitted to the central control station later, helping protect against data loss. PetroChina has praised the TBox’s built-in cyber security suite with authentication and encryption technology, which provides state-of-the-art protection of the customer’s assets and data. This example shows that CNI managers can embrace the advantages of Industry 4.0 without compromising cybersecurity. With the right technology like RTUs in place, let us hope that 2020’s cyberattack records remain unbroken in the future.

reliably locate methane leaks
M
ethane (CH4) concentrations in the atmosphere have increased by more
than 150 per cent since 1750 and are considered a major contributor to global
warming. CH4 has been identified as an even more powerful greenhouse gas than CO2, making an immediate reduction of emissions
necessary. Given its short-lived nature, there are actionable options that reduce the environmental burden on a short timescale. In
the US alone, around 13 million tons of CH4 are being released into the air each year - enough to heat ten million homes for a year. Studies show, however, that only about 40 per
cent of CH4 in the atmosphere originates from natural sources such as volcanoes or permafrost soils, while the remaining percentage is caused by human activities.
Reducing that portion of the total CH4 emissions has thus become a priority for leading nations across the globe, as only then will it be possible to achieve the goals of climate initiatives like the Paris Agreement. And although anthropogenic emissions come from a variety of sources, the oil and gas industry represents the energy sector’s largest source of emissions, holding the key to responding to the world’s climate challenge. Relying on its market-leading
environmental and air quality sensing know- how paired with expertise in scaling solutions into high volumes, Sensirion is developing a stationary methane leak detection system, Nubo Sphere, for use along the whole oil and gas value chain. It is an end-to-end solution for real-time monitoring of methane emissions, offering high performance at low total cost of ownership. The compact and robust system design enables reliable and highly accurate data from any natural gas infrastructure at all times via data upload to the Nubo cloud. It is fast to deploy and easy to use, while two exchangeable sensor cartridges ensure low maintenance expenses and provide a future-proof, sustainable set-up. The system follows the concept of plug and play: mount your Nubo Sphere nodes on-site and start measuring within minutes.
