Often oilfield fractured horizontal wells produce water flowing in multiple directions. In this study, a method to identify such channeling paths is developed. The dual-medium model based on the principle of inter-well connectivity and considers flow characteristics related terms. Lorentz curve drawn qualitatively discern geological type low-permeability reservoir determine direction size. prac...

BACKGROUND The unique surface sensitivity and the high resolution that can be achieved with helium ion microscopy make it a competitive technique for modern materials characterization. As in other techniques that make use of a charged particle beam, channeling through the crystal structure of the bulk of the material can occur. RESULTS Here, we demonstrate how this bulk phenomenon affects sec...

As a first step toward the elucidation of the systems biology of the model organism Escherichia coli, it was our goal to mathematically model a metabolic system of intermediate complexity, namely the well studied end product-regulated pathways for the biosynthesis of the branched chain amino acids L-isoleucine, L-valine, and L-leucine. This has been accomplished with the use of kMech (Yang, C.-...

Discrete fracture network (DFN) model simulations, where a fracture network can have a natural heterogeneity, is one of the most effective approaches in fluid flow analyses for naturally fractured and enhanced geothermal reservoirs. In the DFN model simulations, fractures are modeled by a pair of parallel smooth plates although real fractures have rough surfaces. Numerous field and laboratory o...

Abstract Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency heat balance of grease-lubricated depend strongly on the lubrication mechanisms channeling circulating, for which grease flow is causal. computational fluid dynamics opens up possibility to visualize understand more detail. In this study, a single-stage gearbox l...
