Experimental Simualtion Of Hot Fluid Injection Process for In-reservoir Upgrading
… easily to the surface. A high heat capacity fluid could eventually replace steam in this role. Vacuum Residue (VR) is the heaviest, most viscous and richest in contaminants amongst the different bitumen fractions, thus is the one deserving most upgrading, and it also has the highest heat …

A Computational Analysis of the Aerodynamics and Aeroacoustics of Jets with Fluid Injection
<p>A detailed numerical analysis of fluidic injection as a tool to reduce noise emission is presented here. The noise reduction strategy, developed at the Pennsylvania State University, is based on injectors that blow air into the diverging section of the nozzle to emulate the effect of interior …

Effect of Endwall Fluid Injection on Passage Vortex formation in a First Stage Nozzle Guide Vane Passage
… where vortical flows cause the flow of hotter fluid in the mainstream to mix with relatively lower temperature boundary layer fluid. This work documents the computational investigation of air injection at the end wall through a cylindrical hole placed upstream of the nozzle guide vane leading …

Time Series Analysis of Surface Deformation Associated With Fluid Injection and Induced Seismicity in Timpson, Texas Using DInSAR Methods
… rate in these regions (Ellsworth, 2013). As fluid is pumped into deep formations, the state of stress within the subsurface changes, potentially reactivating pre-existing faults and/or causing subsidence or uplift of the surface. Therefore, hydraulic fracturing and/or fluid disposal injection …

The Influence of Design and Operational Parameters on Microniser Performance
The design of the microniser fluid energy mill has developed since its introduction in 1932. The literature tracing this development is reviewed and earlier work by several researchers concerning the influence of the various operational features is reported upon. The research programme described in …

Mathematical and Computational Modeling of Injection-induced Seismicity
It has long been recognized that pumping fluids into or out of the Earth has the potential to cause earthquakes. Some of the earliest field evidence dates to the 1960s, when earthquakes were turned on and off by water injection in Rangely, Colorado. More recently, induced seismicity has been …

STRESS AND FREQUENCY DEPENDENT PROPERTIES OF POROELASTIC ANISOTROPIC ROCK
The poroelastic response of fluid saturated porous rock due to stress variations is of interest in geophysics and geomechanics as it has practical applications in reservoir depletion, fluid injection, time-lapse monitoring, and carbon dioxide sequestration. The effective stress in a poroelastic …

Predicting the Dynamics of Injection-Induced Earthquakes
Human activities associated with the injection of fluids at depth are known to trigger earthquakes. Fluid injection increases the internal pore pressure of the host rock, which in turn reduces the effective stress and frictional resistance of faults that maintain the fractured rock system in a …
