We report evidence in GaP and InP nanowires for a coherent modulation of the structure along wire axis. By using electron diffraction, we have observed an additional series diffraction peaks consistent with quasiperiodic placement twinning boundaries wire. This observation is indeed unexpected, as vapor−liquid−solid growth conditions used to produce were not modulated. The averaged repeat distance structure, i.e., between twin boundaries, has been found depend on temperature gradient imposed...
Hydraulic fracturing is a widely used method for well stimulation to enhance hydrocarbon recovery. Permeability, or fluid conductivity, of the hydraulic fracture key parameter determine production rate, and principally conditioned by geometry distribution encased proppant. A numerical model developed describe proppant transport within propagating blade-shaped towards defining conductivity reservoir after closure. Fracture propagation formulated based on PKN-formalism coupled with advective...
Cryogenic fracturing with liquid nitrogen (LN2) offers the benefits of reducing water consumption and adverse environmental impacts induced by water-based fracturing, as well potentially enhancing fracture complexity. We performed a series laboratory experiments to explore key mechanisms governing breakdown pressures shale during cryogenic fracturing. In this study, cylindrical samples were pre-conditioned exposing borehole low-temperature LN2 for certain time period, then, fractured using...
Summary Understanding fracture height growth can be of great significance to optimizing field development and improving recovery. The Hydraulic Fracturing Test Site 2 (HFTS-2) has provided a unique opportunity an advanced data set allow us observe understand geometries rigorously. Low-frequency distributed acoustic sensing (LF-DAS) from vertical well in HFTS-2 showed three key observations: (i) excessive upward (>1,000 ft) limited downward the hydraulic fractures during pumping, (ii)...
Summary Effective proppant placement has been one of the key objectives hydraulic fracturing. Different and fracture fluid characteristics methodologies have historically applied based on learnings from standard transport studies with parallel plate slots. The test setup represents a simplified planar constant width confined height, incorporating only basic flow characteristics, thus, is inadequate to capture unique phenomena in unconventional reservoirs. In this study, laboratory tests were...
