Fracking, or Hydraulic Fracturing, is a method to stimulate or improve fluid flow from rocks in the subsurface. Advancements in extraction technologies have enabled drillers to reach previously inaccessible gas in geological formations The technique involves pumping water-rich fluid into a borehole until the fluid pressure at depth causes the rock to fracture. The pumped fluid contains small particles, such as quartz-rich sand or chemicals, which serve to prop open the fractures. After the fracking job, the pressure in the well is dropped and the water containing released natural gas flows back to the well head at the surface. Fracking … Continue reading →
Recent events in the Europe and the United States have propelled fracking up the public and political agenda. Is the case for drilling full of holes? Despite apparent economic benefits, fracking has got entangled in a good deal of controversies with some countries outrightly banning or suspending it. Public health concerns, environmental issues, geomechanical risks, groundwater contamination, air pollution and waste management are some of the issues are coming under increasing public scrutiny. No Sense of Well-being The oil and gas industry does not inspire huge public confidence, as attention focuses on major incidents like the Deepwater Horizon blowout, which have cost lives, caused … Continue reading →
