Chevron and Wintershall join Statoil and ExxonMobil in Badger Explorer

Majors develop cutting-edge subsea drilling technology

2B1st_Project_Smart_Explorer_Sales_Pursuit_ToolOn February 2013, the German Wintershall oil and gas company has decided to follow Chevron example in taking shares in the subsea drilling innovative company Badger Explorer aside its key stakeholders ExxonMobil and Statoil.

ExxonMobil-Chevron-Statoil-Wintershall_Badger-Explorer_Driiling_InnovationWith the ambition to increase its footprint in the offshore exploration and production in the Norwegian North Sea, BASF‘s Oil and Gas subsidiary Wintershall is jumping on the opportunity to join the major companies in the revolutionary technology currently developed by Badger Explorer for the subsea exploration and production.

Based in Norway, Badger Explorer was established as a company in 2003 at the initiative of the International Research Institute of Stavanger (IRIS) to develop breaking through drilling and well technologies.

The driving concept, also called Badger Explorer, is to drill directly from the seabed without surface equipment to perform formation and reservoir evaluation.

With this solution, Badger Explorer shall be able to monitor the reservoirs continuously online without all the costs, complexity and risks of drilling conventional exploratory wells from a rig or a drilling ship.

The Badger Explorer combines proven technology and proprietary solutions to drill in subsurface conditions.

Once installed by a vessel, Badger Explorer is burying itself in the seabed to drill down hole.

Badger Explorer is designed as a drill bit:

 – Powered by only 10 kW electrical motor and gear

 – Equipped with sensors

 – Featured with communication and data transmission systems

With this equipment Badger Explorer is able to

 –  Handle cutting and compression constraints

 – Deploy an integrated electrical cable for power supply and data transmission

 – Record data about formation and reservoir

 – Sustain long term continuous data monitoring and reporting

 – Reach 3,000 meters depth from the seabed

 – Drill at 2 meters per hour

ExxonMobil – Shell – Statoil funded Prototype Program

The Badger Explorer development program has been articulated around three phases:

 – Prototype Program

 – Demonstrator Program

 – Field Pilot Program

In May 2005, ExxonMobil, Shell and Statoil funded the Prototype Program which then has been completed in August 2012.

In January 2012, ExxonMobil and Statoil kicked off the Demonstrator Program in order to design the commercial version of Badger Explorer.

This Field Pilot Program is targeting to expose the Badger Explorer to a series of formation and reservoirs scaling up the technical and operations challenges.

In joining now, Chevron and Wintershall are going to:

 – Provide Badger Explorer with their respective subsea expertise

 – Add their own requirements for the development Badger Explorer at a key period of the Demonstrator Program

With Badger Explorer, ExxonMobil, Chevron, Statoil and now Wintershall are expecting major savings on exploration and production expenses.

Compared with using conventional drillship or rig, Badger Explorer should provide companies with 60 to 80% costs reduction.

Such figures indicate also that the companies partnering in Badger Explorer could perform many more discoveries for the same exploration and production budget.

In addition this technology would reduce risks and environmental impacts so that it should fit perfectly with Arctic and deep offshore conditions.

All along the exploration phases, Badger Explorer is saving costs and time so that the partnering companies  should be able to reduce the cycle time from first discovery to development to 3 or 4 years.

For all these reasons BASF‘s Wintershall and Chevron decided to join ExxonMobil and Statoil into Badger Explorer and to accelerate the implementation of its Demonstrator Program.
