Gas-driven fracturing underlies both natural and industrial processes, such as volcanic degassing, methane venting, stimulated hydrocarbon extraction, and treatment of contaminated soil. The authors show how in such a complex system the capillary, frictional, and viscous interactions together produce a range of fracture patterns, with cracks separated by a characteristic length that varies based on the conditions. Discovering how material properties and injection rate affect these patterns helps to establish a physics framework for optimizing permeability and assessing risk in gas-driven fracturing of hydrocarbon reservoirs and remediation of polluted soil.

David and Deren presented their work at the 3rd Interpore UK Conference which took place at the University of Warwick, 4th – 5th September.
Deren even won the BEST POSTER award for his poster on “Three-Phase Flow and Fracturing of Deformable Porous Media”!
The new Norwegian Center of Excellence Porous Media Laboratory (PoreLab) is underway. The “kick-off“, and first international conference was held in Oslo, 6th to 8th September 2017. The center focuses on the physics of porous media using experimental, theoretical and computational methods.
