.... This method has been demonstrated successfully in lab-scale experiments. The simulations, based on lab-scale geometry, verify the experimental observation and frictional cohesion, the key parameter to control pulling force, is quantified. The field-scale simulation indicates a significant reduction...

... ABSTRACT: The intersection of the pre-existing natural fractures (NF) with the hydraulic fractures (HF) forms a complex fracture network, which allows for increased well productivity. However, the complex fracture geometry may adversely affect the proppant placement and its transportation...

... ABSTRACT: Rock block geometry (size, frequency, and shape) is an important characteristic in many rock engineering studies including rock mass classification, discrete element method, surface and underground stability analysis, drilling, blasting design and hydro-geological analyses...

Additionally, the geometry that stabilizes in one in which detection of crack initiation is challenging. Hence, it is instead recommended to leverage this size dependence as an advantage, noting...

... ABSTRACT: The behavior of intersections is central to the fluid flow and transport evolution of a fracture network in response to chemical and physical processes. Here, laboratory experiments were performed to explore the evolution of network geometry during loading of a 3D printed fracture...

... the durability of PDC cutters without compromising the cutter aggressiveness, the planar diamond table with modified cutter edge geometry was experimentally investigated. The experiment included progressive drop test (PDT) and vertical turret lathe (VTL) wear test. The cutting forces were measured using...

... soaking in slick water for 48 hours, the conductivity can be reduced by about 28.79%. Fracture geometry has a great influence on the conductivity, both diverting fractures and branching fractures make fluid flow channels longer, thus reducing the conductivity by 33.34% at the most. The effect...

... ABSTRACT: In this study, 3DEC modeling in conjunction with the Discrete Fracture Networks (DFNs) technique was performed to better understand the behavior of shearing faults in a relatively large-scale direct shear test model. The DFNs explicitly generated two different geometries of the fault...

... of wellbore shape on cement sheath integrity and zonal isolation. To diagnose cement sheath integrity, cylindrical wellbore models which contain circular-shape casing, cement, and formation layers have been built. However, the wellbore geometry in real drilling process is elliptical instead of circular...

... the microscale geometry can be realistically represented. The THMC model was achieved by linking a microscale mechanical code based on the numerical manifold method (NMM) to the reactive transport model Crunch. Using this first-of-its-kind microscale model, we show the results of compaction within a halite...

It becomes more vital and sophisticated with the increase of well depth, not only by the effects of fluid properties, rotation and eccentricity but also by the increasing number of tubing collars and tool joints. The presence of a tubing collar or a tool joint changes the annulus geometry...

However, the results for fracture characterization can be incomplete due to interpretation and inversion methods that are limited by a lack of integrated geomechanical models. In the paper, a geomechanical...
