The politics of hydraulic fracturing in Germany : party competition at different levels of government [PDF]

, 2016
Hydraulic fracturing has been practiced in Germany for decades, and several attempts have been made to legalize and regulate new drilling methods, which eventually led to the approval of a law to effectively ban this activity in 2016.

Hydraulic fracturing in ice boreholes: Theory and tests [PDF]

, 2019
Hydraulic fracturing is the well-known phenomenon that can occur intentionally, as it is used in the petroleum industry to stimulate the flow of natural gas or oil, or naturally, for example, as a reason for calving of ice shelves.
