Gas Propagated Borehole Fracture Model And Simulation

Nov 15, 2015
58.91 MB
Publicly accessible
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...

Test Report for Detonation Velocity Measurements

Jan 13, 2014
3.82 MB
Publicly accessible
Test report for detonation velocity measurements. A series of tests were conducted to determine reaction rate and general behavior of aluminum (AL) and magnesium (MG) powder mixtures (metalized explosives) with Bullseye double-base smokeless propellant. Given the indeterminate sen...

Testing for Controlled Rapid Pressurization

Sep 03, 2014
297.13 kB
Publicly accessible
Borehole W1 is a NQ core hole drilled at our test site in Socorro. The rock is rhyolite. Borehole W1 which was used to test gas-gas explosive mixtures is 55 feet deep with casing (pinkish in the drawing) set to 35 feet. The model is a representation of the borehole and the hol...

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

Nov 15, 2015
16.88 MB
Publicly accessible
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...

Thermal Drawdown-Induced Flow Channeling in a Single Fracture in EGS

Nov 15, 2015
1.32 MB
Publicly accessible
The evolution of flow pattern along a single fracture and its effects on heat production is a fundamental problem in the assessments of engineered geothermal systems (EGS). The channelized flow pattern associated with ubiquitous heterogeneity in fracture aperture distribution caus...
