Fem Analysis of Proppant Sticking in Rock Cracks

Archives of Civil Engineering, 2018
The problem of effective gas extraction from Polish shale rocks is an interesting research subject for scientists. A properly selected proppant, which protects cracks from closing during the fracturing process, inestimably contributes to an increase of ...

Fracture patterns in midshaft clavicle fractures [PDF]

Acta Orthopaedica Belgica, 2021
Current classifications of midshaft clavicle fractures are based on radiography. The aim of the study was to evaluate the fracture pattern of clavicle fractures using 3-dimensional computed tomography (3D CT). A retrospective analysis was performed on CT scans of 65 acute clavicle fractures.

Seismic studies of the unevenness of open fracturing and inhomogeneity of the fluid saturation in the geological environment for optimal development of oil and gas fields

Georesursy, 2018
The distribution of fracturing and the type of fluid saturation in the geological environment, along with its structure, is the most important information for optimal development of oil and gas fields, including their search, exploration and development.

L-Shape based Layout Fracturing for E-Beam Lithography

, 2014
Layout fracturing is a fundamental step in mask data preparation and e-beam lithography (EBL) writing. To increase EBL throughput, recently a new L-shape writing strategy is proposed, which calls for new L-shape fracturing, versus the conventional ...

Field experiments and main understanding of shale oil hydraulic fracturing

Frontiers in Earth Science
To understand the key processes of hydraulic fracturing in shale oil reservoirs, such as artificial fracture initiation and extension, proppant transportation and settlement, and the influencing factors of post-fracture production, many hydraulic ...

Interaction between Injection Points during Hydraulic Fracturing

, 2012
We present a model of the hydraulic fracturing of heterogeneous poroelastic media. The formalism is an effective continuum model that captures the coupled dynamics of the fluid pressure and the fractured rock matrix and models both the tensile and shear ...

Research on the timing of polymer flooding oil and water well fracturing [PDF]

E3S Web of Conferences
Fracturing technology is the main measure to increase production and injection in oilfield production. With the gradual expansion of the scale of polymer flooding, the proportion of fractured Wells also increases year by year.
