Moreover, it has been utilized in the setting of the packers, plug equipment, and perforation procedures.
Concerning the ankle mosaicplasty procedure, the reported concomitant surgeries comprised the modified Broström operation, cancellous bone grafting between the plugs, subchondral bone perforation, removal of a free intra-articular osteochondral fragments and lateral ankle ligament reconstruction (de l'Escalopier et al. 2015; Kim et al. 2012).
Due to downhole complexities, shale-gas horizontal well fracturing in the Sichuan Basin suffered from casing deformation and failure to apply the technique of cable-conveyed perforation bridge plug.
Punch shear test procedures were employed until the perforation and complete plugging shear out of the laminate.
Based on theoretical analyses and field tests, a design of optimized parameters of coiled tubing-conveyed multi-cluster sand-blasting perforation and temporary plugging by sand filling was proposed.
The fracturing results were assessed and used in real time for the optimization of prepad fluid parameter, perforation and temporary plugging additive releasing time, so as to effectively avoid repeated fracturing and uneven fracturing effects and improve fracturing stimulation effects.
Shadowgraphic data indicate that the presence of perforations on the plug surface results in the weakening and favorable modifications of the repetitive shock structure in the improperly expanded jet flows, leading to the observed reductions in shock-associated noise.
However, in contrast to polymerized collagen I, cell perforation of the Matrigel plugs was not prevented by MMP inhibition (Fig. 2B).
The fat graft was then inserted through the perforation as an hourglass shaped plug.
The staged fracturing technology with temporary plugging balls was conducted in the mode of single perforation, continuous fracturing and staged ball dropping.
