Soundwaves May Help Increase Future Oil Production

Low frequency sound waves may in future be used to recover leftover oil from oil wells on the Norwegian continental shelf, reports said Thursday.

Oil is currently extracted by pumping sea water down into one well to replace oil pumped up to the surface of another well. Initially, mostly oil is pumped to the surface, eventually more sea water is pumped up and the well is declared ‘empty.’

Estimates however suggest that the well still contains some 30-40 per cent of its oil.
