Who are we

Robert te Gussinklo Ohmann

After completing his Petroleum Engineering study at Delft University Robert began his working career in 2001 working for BECi B.V. designing and developing salt and gas wells. Through this work he moved to Frisia Zout B.V. where he became Head of Mining. In 2008 he became Operations Manager for Northern Dutch Drilling Company (NDDC), operating a novel concept Huisman Drilling Rig on gas and geothermal wells in the Netherlands and Denmark. As NDDC was owned by Verkley, Robert also became actively involved with pipeline work, both in Europe and the Middle-East.

In 2011 Robert started Holland Drilling Group (HDG), involved in a wide variety of drilling related projects, ranging from geothermal permit applications in the Netherlands to acquiring a drilling contract in New Zealand, and developing a real-time web-based drilling operations monitoring system (RemoteView ©). This was followed by the start-up of Spidron B.V. in 2014, where Robert continued to provide a wide range of services to (primarily) geothermal energy projects.

In 2017 Spidron B.V. merged with Roaring Forties B.V. to form Spidron Weco B.V.

Rein Bootsma

Rein studied Mechanical Engineering at Polytechnic College in Leeuwarden (HTS), after which he joined Shell to work as international drilling staff member.

In 1989 Rein emigrated with his young family to the UK to work as a Drilling Engineer and Drilling Supervisor for Shell UK Exploration and Production from Lowestoft. After six years of service he was moved to the Sultanate of Brunei, where he worked on a wide variety of oil- and gas wells, both onshore and offshore, ranging from new-drilled wells, to repairs and workovers, abandonments and interventions. He worked as Drilling Engineer, HSE focal point and Drilling Supervisor, was closely involved in the set-up of Emergency Command and Control for drilling operations and with the so-called “Technical Limit” approach. He coached several local staff through their Round I and II self-study packages.

Rein returned to the Netherlands in 2000 and quit Shell in 2001 to set-up a drilling consultancy business, eventually named Roaring Forties B.V. Besides some minor projects he worked for Clyde Petroleum, Nederlandse Aardolie Maatschappij, Wintershall Noordzee, Vermilion Oil and Gas Netherlands, Vermilion REP SAS (France) and Oranje-Nassau Energy B.V.
