Oil and Gas Sensing

Oil extraction is becoming ever more challenging as existing reservoirs produce less oil. Furthermore, to a large extent, oil and gas are being exploited at sea levels down to 3 kilometers causing major challenges for the operation and lifetime of equipment for both oil extraction and sensing.

Locate oil with Koheras lasers

Optical sensing systems are gaining ground because they offer several advantages over traditional technologies based on electrical transducers, e.g. piezoelectric hydrophones.

New interferometric systems with fiber optical sensors enable longer sensing ranges with high dynamic range and sensitivity. The fibers are passive (no electronics), compact, lightweight, reliable, and can be multiplexed to interrogate extensive sensor arrays. This is key to obtaining a higher return on investment and – ultimately – a lower cost of ownership.

Today only about 30% of an oil well is exploited over time. However, with permanent reservoir monitoring, it is possible to increase the extraction rate and benefit from the existing infrastructure around an oil reservoir.

The optical sensor system listens to an “acoustic signature” from the seafloor, providing means to identify and locate oil “pockets” that are otherwise difficult to access.

Our market-leading low phase noise is crucial for obtaining a high dynamic range and sensitivity in an optical sensor system.

Robust, reliable, and a long lifetime

Our industrial Koheras fiber laser modules have been used in the oil & gas industry for many years and are currently the backbone of several seismic sensor systems.

The fiber laser design is inherently compact and robust. It is developed for a long lifetime in demanding environments where uptime is critical. With documented low failure rates, we proudly deliver the most reliable low noise lasers on the market.

We have more than 10,000 Koheras lasers deployed in the harshest environments on – and off – the planet. We have lasers on oil-rigs, in submarines, on wind turbines, and even in space. With 20 years of experience, we know they last.
