Abstract Understanding the formation mechanisms of complex fracture networks is vitally important for hydraulic fracturing operations in shale formation. For this purpose, a experiment under core-plunger scale conducted to investigate impact bedding plane angle, borehole size, and injection rate on initiation behaviors laminated rock. The results rock properties demonstrate that anisotropic cha...

Abstract The interaction between hydraulic fractures (HF) and natural (NF) is one of the most fundamental phenomena in fracturing. near-wellbore HF NF significantly affects fracking-related operations including injected fluid flow, proppant transport well productivity. However, nature fracturing modes, combined with hydro-mechanical coupling, poses great difficulties challenges addressing this ...

background: accumulation of pleural and peritoneal fluid is seen in some diseases. in order to diagnose the disease and start the treatment, one of the most important actions will be to differentiate between exudates and transudates. the objective of this study was to determine the diagnostic value of measuring the specific gravity of the fluid through refractometer and strip in differentiation...

As a direct outcome of economic development coupled with an increase in population, global energy demand will continue to rise the coming decades. Although renewable sources are increasingly investigated for optimal production, immediate needs require focus on that currently available and reliable, minimal environmental impact; efficient exploration production unconventional hydrocarbon resourc...

The third member of Weixinnanliu in the west South China Sea develops thin interbeds, and vertical extension fracturing fractures is excessive. Once extend vertically to upper lower aquifers, it easy cause water flooding oil wells, effect after not obvious. present work aims explore longitudinal law Low Permeability Thin Interbed Reservoir based on finite element calculation platform. A three-d...

Abstract A series of true axial hydraulic fracturing experiments were conducted to understand the complex fracture initiation and propagation behavior multilayered rocks. Moreover, a new convenient grid measurement method was presented describe effectiveness. The experimental results revealed that transverse vertical non-planar fractures could be created in area scanning by match indicated trad...
