Post-treatment horizontal hydraulic fracture modeling with integrated chemical tracer analysis, a case study
… water flooding, resulted in the development of chemical tracer technologies. While the utilization of tracer technologies to track water during reservoir development is mature, the use of chemical tracers in unconventional hydraulic fracturing operations is relatively new. With the increasing …

Nanoparticle Transport Through Fractures And Heterogeneous Porous Media
… couple of orders of magnitude smaller than inert chemical tracers such as potassium bromide (KBr), and this means that they can potentially be used to measure the degree to which subsurface flow occurs through fractures and high permeable zones in heterogeneous porous media. Using carbon based 2-5 …

The East Greenland Coastal Current : its structure, variability, and large-scale impact
… This observation, combined with evidence from chemical tracer measurements that imply the EGCC contains a significant Pacific Water signal, suggests that the EGCC is an inner branch of the polar-origin East Greenland Current (EGC). A set of idealized laboratory experiments on the interaction of …

Tracing Wyville Thomson Ridge Overflow Water in the Rockall Trough
… Atlantic for the first time. Using a variety of chemical tracer s (chlorofluorocarbons, oxygen, nutrients and aluminium) in conjunction with temperature and salinity, WTOW is traced southwards into the northern and central Rockall Trough as well as into the channels between the western banks. The …

The effects of dopants and complexions on grain boundary diffusion and fracture toughness in α-Al2O3
… abnormal grain growth, were found to derive from chemically or thermally induced grain boundary phase transitions or complexion transitions. This work investigates the hypothesis that such complexion transitions could also impact grain boundary diffusivity and grain boundary mechanical strength. …

Runoff from hummock-covered Arctic tundra hillslopes in the continuous permafrost zone
… of active layer and water table depths, chemical tracer-based measurements of subsurface flow velocities, continuous and spot measurements of surface and subsurface discharges, detailed mapping of the hummock distribution and soil types, and continuous gauging of the main stream channel. …
