hydraulic fracking

Hydraulic fracturing is the fracturing of various rock layers by a pressurized liquid. Some hydraulic fractures form naturally—certain veins or dikes are examples—and can create conduits along which gas and petroleum from source rocks may migrate to reservoir rocks. Induced hydraulic fracturing or hydrofracturing, commonly known as fracing, fraccing, or fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction.[1] This type of fracturing creates fractures from a wellbore drilled into reservoir rock formations.

This year, we witnessed the United States’ carbon emissions drop to a record level, one that hasn’t been seen in the last 20 years. Lots of people started shouting and spreading misinformation, claiming that renewable energy and all those green measures were responsible for this remarkable feat. It would be great if this were true [...]

Shale gas isn’t a ‘clean bridge fuel’, study finds

Sat, Jan 21, 2012

2 Comments

There has been a lot of fuss lately about shale gas, which has become increasingly important in the past decade, particularly due to hydraulic fracturing (or fracking), a modern technique used to extract it from the underground. Many have proposed natural shale gas as a supposedly clean bridge fuel, fit to address climate change and [...]
