Abstract Hydraulic fracturing in shale gas reservoirs has often resulted complex fracture network growth, as evidenced by microseismic monitoring. The nature and degree of complexity must be clearly understood to optimize stimulation design completion strategy. Unfortunately, the existing single planar models used industry today are not able simulate networks. A new hydraulic model is developed propagation a formation with preexisting natural fractures. solves system equations governing...
Summary. Hydraulic-fracturing treatments have become an indispensable part of well completion in shale gasfield development. Shale formations often contain natural fractures, and complex hydraulic-fracture networks may form during a treatment. The fracture network is strongly influenced by the interaction between hydraulic pre-existing fractures. A criterion has been developed to determine whether crosses frictional interface (pre-existing fracture) at nonorthogonal angles. This extension...
Summary Hydraulic fracturing in shale-gas reservoirs has often resulted complex-fracture-network growth, as evidenced by microseismic monitoring. The nature and degree of fracture complexity must be understood clearly to optimize stimulation design completion strategy. Unfortunately, the existing single-planar-fracture models used industry today are not able simulate complex networks.

Abstract A recently developed unconventional fracture model (UFM) is able to simulate complex network propagation in a formation with pre-existing natural fractures. Multiple branches can propagate simultaneously and intersect/cross each other. Each open exerts additional stresses on the surrounding rock adjacent fractures, which often referred as "stress shadow" effect. The stress shadow cause significant restriction of width, leading greater risk proppant screenout. It also alter path...
Abstract Microseismic mapping (MSM) has shown that the occurrence of complex fracture growth is much more common than initially anticipated and becoming prevalent with increased development unconventional reservoirs (shale-gas). The nature degree complexity must be clearly understood to select best stimulation design completion strategy. Although MSM provided significant insights into hydraulic complexity, in many cases interpretation been limited due absence evaluative predictive models....

To address the challenge of heat transfer enhancement in condensation steam with non-condensable gases on a vertical wall under natural convection conditions, an improved boundary layer model coupled multi-physics field was proposed this paper, and traditional theoretical limitations were broken through by innovations. The particle swarm optimization algorithm first introduced into solution layer, convergence difficulty laminar–turbulent transition region infinite conditions overcome. A...
Abstract Interfacial slip is one of the mechanisms that can alter growth a hydraulic fracture when it encounters weak planes or natural fractures. In shallow over-pressured formations, interfacial between formation bedding possible effective normal stress on interfaces low. Fracture height could be hindered stopped by vertical propagates in such formations. An model has been developed and implemented pseudo-three-dimensional (P3D) simulator. model, width deformation with calculated using...
A new nortriterpenoid, 19(R)-hydroxyl-wuweizidilactone H (1), and a sesquiterpene, (6R)-β-chamigrenic acid (2), together with one known wuweizidilactone (3), three hepatoprotective lignans, micrantherin (4), gomisin M₂ (5) schizandrin (6) were isolated from the fruit of Schisandra chinensis. Their structures elucidated by UV, IR, HRESIMS, NMR spectra X-ray analysis. Among them, absolute configuration 2 was confirmed for first time. In vitro assays, compounds 4-6 (10 μM) exhibited activities...
Bubble columns are effective means of filtration in filtered containment venting systems. Here, the surface tension has a significant influence on bubble size distribution and deformation, which have strong impact behavior column. The aqueous inorganic compounds depends electrolytic activity, Debye length, entropy ion hydration deficiencies or excess. In this work tensions same specific solutions been measured by different methods including platinum plate method, ring method maximum pressure...
This paper presents a theory and its application for post-fracture pressure-transient analyses. The proposed procedure, known as “impulse fracture test,” is an injection/falloff test designed the determination of formation permeability reservoir pressure. hydraulically induced can pass near wellbore damaged zone expose larger area to flow. pressure determined are therefore more representative reservoir. based on distribution sources with variable intensity along trajectory. For field...
