Jams and Cakes: A Closer Look on Well Clogging Mechanisms in Microscale Produced Water ReInjection Experiments

Particle Clogging in Radial Flow: Microscale Mechanisms

Fluid-flow-driven particle migration through porous networks reflects the interplay between various particle-level forces, the relative size between migrating particles and pore constrictions, and the spatial variability of the velocity field. Experimental evidence shows that particle migration in radial fluid flow results in selfstabilizing annular clogging patterns when the particle size appr...

A closer look at supercritical water.

Water, the fluid of life at ambient pressure (P) and temperature (T), is mostly present under supercritical conditions in the Earth’s crust and mantle (1): that is, above the vaporliquid critical point (647 K and 221 MPa). As a free fluid or dissolved in silicate minerals, supercritical water greatly influences the structure and dynamics of our planet. From a technological standpoint, there are...

A closer look at water-related geologic activity on Mars.

Water has supposedly marked the surface of Mars and produced characteristic landforms. To understand the history of water on Mars, we take a close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter, reaching fine spatial scales of 25 to 32 centimeters per pixel. Boulders ranging up to approximately 2 meters in diameter are ubiquito...

A ClOser lOOk

In recent years, systems of care principles have been increasingly adopted because of their potential to support efforts to improve child welfare and other human service systems in ways that lead to increased safety, permanency, and well-being for children, adolescents, and their families. However, while the systems of care approach has become more widespread, a clear understanding of what defi...
