To gain a deeper understanding of a wide range of geological processes, such as plate tectonics, earthquakes and volcanic diking, we need to have a knowledge of both past and present in situ stress ...

The foam fracture fluid is full of energy and begins to flow back to the surface readily when fracture pumping has ceased. The energized fluid is especially helpful in promoting frac-fluid flowback ...

Water flow through rock layers above coal seams impacts mine safety. New research detailed sandstone pore structure using ...

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 ...

Hydraulic fracturing is a completion technique that pumps high-pressure fluid and proppant into a low-permeability reservoir to create and prop open fractures, increasing flow paths so oil can move to ...
