15 YEAR ANNIVERSARY – 2005-2020

North Sea Electronics celebrates 15 years of operation in January 2020.

Another five years has passed since we celebrated our 10year anniversay in 2015. This period has been both challenging and the best in the history of the company. After a rough 2016, NSE has shown significant growth the last couple of years. The last year alone gave an increase in revenue of 30% compared to 2018. We have had a significant growth in North America the last 3-4 years, and we are looking forward to continue this growth in the years to come.

NSE has now a complete portfolio of electronics to equip almost any downhole tool. NSE is pleased to see that more and more companies around the world realize the great advantage by using off-the-shelf modularized components. This eases the design, shorten the time to market, and lets the customer focus on getting into operaton.

The telemetry systems that has been the flagship for the last 10 years has recently been released in new and smaller topside and downhole versions. This opens  new markets related to logging and camera services. At the end of 2019 there are more than 350 individual telemetry systems operating world-wide in variety of tools; tractors, strokers, cameras, plugs, etc. We expect this quantity to be doubled within the next couple of years. During 2020 we will release another downhole telemetry unit integrated in a DCDC converter providing a steady 600Vdc output (up to 1200Vdc input) – in addition to the best wireline telemetry system available. Stay tuned and follow us on LinkedIn for more updates.

We are all looking forward to the coming 15 years – and will continue supporting our great customers – and hopefully meet lots of new ones!

At last but not least – a HUGE thanks to our loyal employees that are the brains and hands behind our fantastic products. – I’m proud and honored to work with you!
