Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319

open access: yes, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure

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

open access: yes, 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

open access: yes, 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.

Multi-phase fluid-loss properties and return permeability of energized fracturing fluids [PDF]

open access: yes, 2012
textWith the growing interest in low-permeability gas plays, foam fracturing fluids are now well established as a viable alternative to traditional fracturing fluids. Present practices in energized fracturing treatments remain nonetheless rudimentary in
