Thus, foam, polymer and other profile modifying and plugging materials are used to improve steam injection profile and block breakthrough channels (Djabbarah and Weber 1990; Cheng et al. 2004; Wu et al. 2011; Wang et al. 2012a).
For well closure, water is indirectly used for land reclamation, plugging materials and energy consumption.
The fracture is difficult to widen for filling more plugging materials in a short time while the lost circulation rate and permeability are low.
If one substitutes the plug material by a radionuclide, microdosimetry spectra could be measured for internal dosimetry applications.
The effects of plug material, joint design, and welding variables on the weld defects, microstructural characteristics, hardness levels, and tensile properties were investigated.
The reduction in fatigue life is most likely due to the complication of weld geometry, interacting heat affected zones, and strength mismatch between base metal, friction stir weld, and plug material.
The underwater stitch welding performed with a S355 steel plug exhibited visible bonding defects at the weld interface, while the weld with LF2 as the plug material yielded a qualified joint without cracks or discontinuities, provided the plug and hole geometries were well-designed.
When these brief pulses occurred, plug material was always found in the female atrium, indicating that they are responsible for the transfer of plug material.
The separate openings facilitate the release of plug material independent of sperm transfer.
The relative amount of plug material was transformed using angular transformation in order to homogenize variances.
