PetroMarker’s EM exploration technology is particularly environment friendly. Not only the effect of the EM pulsing decays within metres of the source, but the fact that the vessel is stationary while pulsing adds to the limitation of the environmental impact.

While our vessel, “Volstad Surveyor”, was surveying a potential prospect in the West of Shetland, a school of whales kept us company. As many of 30 of them seemed to enjoy our presence for days.
