Oil majors keen on magnetic mapping

…
WHEN you are drilling for oil deep down on the ocean floor, how do you know if the reservoir you’ve found is full of fossil fuels or soaking in salt water?

The answer for big oil companies, who waste millions of dollars drilling into so-called “dry holes”, is an up-and-coming technology called electromagnetic mapping to pinpoint hydrocarbons, the main constituents of oil and natural gas.

Until recently, companies relied almost exclusively on seismic surveys, which use acoustic waves generated by explosions, to scour the sea floor for the right geological formations where oil and gas are mostly found.
