What? A new technology has been developed for the removal of hydrocarbons from oil shale, tar sands, tight shales, and conventional oil and gas reservoirs using a High Power Microwave system. This can replace conventional hydrofracturing and eliminate the need for large quantities of water and chemicals that are injected into the ground and the associated disposal costs as well as offer an alternative method for removing contaminants from soils. This offers tremendous potential in areas of actual or perceived environmental sensitivity or where available water is simply not sufficient for fracking activities.
So what? Power microwaves have the potential to clean up the oil business. The overall effect is similar to fracking, but with none of the chemicals or contaminated water.
