Gas Propagated Borehole Fracture Model And Simulation

We developed a model for fracture production produced during detonation of an explosive mixture in a 10m packed off section of a shallow borehole. The model is based upon an actual field and lab experiments on low-damage borehole fracturing performed at Sandia National Labs by Mar...

Thermal Drawdown Induced Flow Channeling in Fractured Geothermal Reservoirs: Rock Mechanics and Rock Engineering

We investigate the flow-channeling phenomenon caused by thermal drawdown in fractured geothermal reservoirs. A discrete fracture network-based, fully coupled thermal "hydrological" mechanical simulator is used to study the interactions between fluid flow, temperature change, and t...
