Hydraulic fracturing
(
fracking
) techniques can be used to recover
natural gas
as well as
oil
buried in
shale
underground deposits.
A well is drilled and extended
horizontally
.
Explosives
fracture
the rock.
Hydraulic pressure is applied to the fractures.
Escaping gas is collected.
Side effects of
shale gas
and
shale oil
recovery may include contamination of soil and groundwater.
