Hydraulic stimulation strategies in enhanced geothermal systems (EGS): a review
In enhanced geothermal systems (EGS), the natural permeability of deep rocks is normally
not high enough and needs to be increased. Permeability increase can be achieved through …

Widespread deep seismicity in the Delaware Basin, Texas, is mainly driven by shallow wastewater injection
Industrial activity away from plate boundaries can induce earthquakes and has evolved into
a global issue. Much of the induced seismicity in the United States' midcontinent is attributed …
