However, the study on radial well fracturing is still at the preliminary stage, the fracture morphology and propagation law of radial well fracturing still remain unclear, especially lacking visual achievement, which limits the development and application of radial well fracturing.
Moreover, the fracturing process, operation mode, surface facilities and post-fracturing preliminary evaluation of the zipper-fracturing in the well group were examined comprehensively.
Approximately a half hour later, plain radiographs of the right elbow revealed an elevated posterior fat pad (Fig. 2c) but no other evidence of fracture on preliminary read.
A half hour later, plain radiographs of the left elbow revealed an elevated posterior fat pad (Fig. 3c) but no other evidence of fracture on preliminary reading.
Often, the two approaches are used sequentially, with S N being used at the design or preliminary assessment stage and fracture mechanics for more refined remaining life or inspection and repair estimates.
Gov. Andrew Cuomo's preliminary blueprint for hydraulic fracturing in New York State strikes a sensible balance between the need for economic development and the need to protect the environment and human health.
Preliminary investigation suggested that the fracture was brittle with no visible evidence of plastic deformation.
The analytical and experimental results are also used for a preliminary quantitative evaluation of a fracture mechanics based failure criterion for the strengthened beam.
This glass can be successfully used to coat Ti implant alloys, and preliminary tests indicate that interfacial fracture resistance is good.
After complete approach, debridement, and fracture fragment assembly, preliminary Kirschner wires (K-wires) were applied smoothly from all aspects around the exposed distal end of the femur (Fig. 3a, b).
