... studies were conducted based on the self-designed true triaxial SC-CO 2 shock fracturing experimental system. The influences of in-situ stress and initial releasing pressure on the morphology of coal fractures were studied. In addition, the pressure evolution characteristics and fracture morphologies...

... to be a function of the equivalent plastic strain as follows: Abstract In this paper, a workflow is proposed to investigate fracture morphology in shale formations, integrating two parts: forward simulation and backward calibration. Uncertainty in the forward simulation should be quantified by backward...

...; and c s is the lattice sound speed. Abstract Gas and water transport behavior, which is controlled by the pore characteristics and capillarity in hydrate-bearing sediments (HBS), is one of the key factors affecting the gas production. Hydrate distribution morphology (HDM) can significantly...

... be attributed to MIC, costing billions of dollars. Close examination of extensive sessile bacteria data, water chemistry and the corrosion damage morphologies observed on corresponding corrosion coupons in different oil field waters (brackish, recycled, produced, effluent) over a period of some 10 years...

... and enhanced thermal and hydrolytic stability compared to contemporary mid-temperature fiber (MTF). Second, the morphology is crimped, which enables better material dispersion and plugging efficiency when designed with higher concentration. Comprehensive laboratory tests were conducted for degradation...

... fractures or cluster-level measurements. With the continued advances in fiber optic technologies, we can now measure cluster level fracture behavior at the wellbore and in the far-field. Characterizing the relationship between wellbore and far-field fracture geometry, referred to as fracture morphology...

... in surface morphology may be occurring. Post well a 3-D inversion of the EM data revealed the 3-D geological structure. During the initial approach, the 1-D inversion indicated that relief of the reservoir top was more exaggerated than expected; the well intersected a sharp peak prior to approaching...

... propagation behavior, and torturous hydraulic fracture morphology for cased and perforated horizontal wellbores in tight sandstone formation. The method is based on the combination of finite element method and post-failure damage mechanism. Finite element method is used to determine the coupling behavior...

... from the oceans. Many estuaries have carried out navigation channel engineering such as the Mississippi River Estuary (USA), the Mersey Estuary (UK), and Rhine Estuary (Netherlands). Regulation projects are carried out in order to stabilize morphology changes and ensure navigation safety. The estuary...

... Abstract A new simplified and practical methodology for the calculation of the equilibrium scour morphology in the clear-water regime is proposed using the bed shear stress amplification as a surrogate for the scour depth. With gradually decreasing scour depth increments, the morphology...

... out, the deformation characteristics of the salt cavity under different pressures are compared, and the allowable pressure interval that meets the operating life of the salt cavity is determined. At the same time, the morphology and stability characteristics of the salt cavity under different well...

... and wherever rock rupture conditions are fulfilled, and the resulted fracture morphology at the same conditions might be different. In this novel method, the uncertainty in fracture propagation direction is also considered to increase its feasibility in reservoirs with ambiguous geological characteristics...

... fractures distribution and their geometry were evaluated by micro CT image technique. Results indicate that the shear strength and fracture morphology are strongly correlated to the brittleness index and bedding inclination. A parabolic correlation between shear strength and brittleness index exists...
