Exploration at Lower Risk, Cost and Complexity
The Badger Explorer is a revolutionary method to obtain subsurface data for oil&gas exploration, mapping of hydrocarbon resources and long-term surveillance.The Badger Explorer drills and buries underground, carrying a unique package of logging and monitoring sensors, at a substantially lower risk, cost and complexity of utilising an expensive drilling rig.
The tool penetrates the sea bed and the subsurface by using a mechanical drill bit driven by an electrical motor to loosen and crush the formation ahead of the tool. The crushed formation is transported through the device and deposited in the void behind the tool. The tool carries an electrical cable, which is spooled up inside the unit, connected to the surface and powers the electrical motors. The same cable is used for continous transfer of data back to the surface.
Please find below the article about the Badger tool in ExxonMobils internal magazine for its Norwegian subsidiary, published in December 2013.
In addition, please find two movies showing the Badger Explorer Tool as it was laid out for Milestone 3 and subsequent module testing as completed for Milestone 4.
