Experimental investigation of proppant transport and behavior in horizontal wellbores using low viscosity fluids
… a widely applied technology for stimulating low permeability reservoirs. The reason for stimulating tight formations is to increase recoverable reserves and to accelerate production. This can be accomplished by placing hydraulic fractures in the targeted formations to allow the flow of oil …

A Study on Vibration-induced Particle Motion under Microgravity
… platforms, however, g-jitter induced convective flow may have resulted in certain effects that reduced the quality of the produced crystals. To investigate the effects of g-jitter on the motion of small particles, experiments were conducted under normal gravity by suspending spherical stainless …

Numerical modeling of interface dynamics and transport phenomena in transport-limited electrolysis processes
… cathode. When the electrodes and electrolyte are low-viscosity fluids, flow stabilizes the interface.

Multi-stage polymer systems for the autonomic regeneration of large damage volumes
… sheets. By splitting the chemistry into two low viscosity fluids, we demonstrated regeneration of gaps up to 9 mm in diameter. The combination of microvascular networks and a new healing chemistry demonstrates an innovative healing system that significantly exceeds the performance of …

Simulating gas production from hydraulic fracture networks : a case study of the Barnett shale
… for the Barnett is a slickwater treatment with low proppant concentrations, because this type of waterfrac is believed to create longer and more complex fracture networks, contacting much greater surface areas of the reservoir while minimizing the fracture face damage through the use of low …

Hydraulic fracturing of artificially generated soft sandstones
… leading to a well, from which hydrocarbons will flow. Many applications of hydraulic fracturing take place in soft sandstones using moderate to low viscosity fluids. Soft sandstones represent the host rock for a large portion of active aquifers and oil and gas reservoirs because their high …

Formation of polymer nanofibers from electrified fluid jets
… as a function of the electric field and the flow rate, operating diagrams were developed. These diagrams delineate regions of different jet behavior, and the stability borders for two transitions have been mapped. The first transition is from dripping to a stable jet; and represents the …

Evaluation of the thermal and mixing performance of an agitated vessel for processing of complex liquid foodstuffs
… showed that the thermal process efficiency is lowered as the fluid viscosity increases when the wall jacket was used alone; this was observed by greater differences between the temperatures recorded by the thermocouples between the centre and the vessel wall. This was overcome by using direct …

Literature review of the use of common protective coatings for concrete structures with experiences in the South African context
… TRANSPORT PROPERTIES The movement of ions or fluids in concrete occurs due to four basic mechanism; diffusion, permeation, absorption and migration, as briefly outlined below. The kinetics of movement is broadly governed by the size and nature of the concrete pore structure and its exposure …

Development of an Injectable Ablative Therapy for Resource-Limited Settings: Applications in Tumor Ablation
… cancer mortality burden is predicted to occur in low- and middle-income countries (LMICs), citizens of these countries have disproportionately less access to resources and facilities to provide effective care. Surgery, radiation therapy, and chemotherapy form the foundation of effective cancer …
