Hydraulic Fractures Induced by Water-/Carbon Dioxide
2019-3-7 To investigate the impact of fluid viscosity and rock heterogeneity on the characteristics (such as geometric complexity, roughness, and micro-morphology) of hydraulic fractures (HFs), laboratory triaxial fracturing experiments were conducted on homogeneous and layered tight sandstones using water- and carbon dioxide (CO 2)-based fluids.The fractal

Development and field application of a pulse-jet hydraulic
2018-12-1 Therefore, the hydraulic impact force should be enhanced in drilling basalt formations, and the pulse jet should be enhanced in drilling sandstone and sandy mudstone. Fig. 9 shows a four-interval chart illustrating the ROP in different formations under fit-for-purpose drilling parameters and tool structural parameters.

Enhancing the Impact Resistance of Historical Stone
This stone describes the dynamic response of sandstone masonry units bound with fibre-reinforced mortars comparing a Portland cement-lime system with hydraulic lime. A drop-weight impact machine was used to generate stress rates up to 107 kPa/s. The dynamic impact factor and stress rate sensitivity were evaluated for the flexural strength of the sandstone and mortar,

Digital rock physics approach to simulate hydraulic
The impact of the chemical precipitation regime on the effective hydraulic rock properties can be quantified by a porosity-permeability relation using a digital rock physics approach. These findings can be now applied for the assessment of equivalent reservoirs to succeed with future projects aiming at utilisation of the geological subsurface

Permeability Variations in Illite‐Bearing Sandstone
Overall, this reduces the load-bearing capacity of the rock at the pore scale yielding some degree of inelastic compaction sufficient to reduce the effective cross sectional area of the pore throats that, in combination, define the hydraulic properties of this sandstone (section 3.2; Figure 5).
