Well fracturing (hydraulic or acid fracturing) increases effective permeability by creating high-conductivity fractures that connect the wellbore to a larger rock volume. It sits in the completion and ...

Hydraulic fracturing (fracking) increases oilfield productivity by creating high-conductivity flow paths that connect low-permeability rock to the wellbore, reduce near-wellbore damage (skin), and ...

Fracking – a controversial method of extracting natural gas and oil from underground – is a deeply divisive topic. Some say it damages property and causes pollution, while others contend it is a safe, ...
