... suspension prepared in this paper is 2000 mg/L. The microscopic morphology of the polymer microspheres is observed by a microscope, as shown in Figure 1 . It can be seen that the microspheres are regular spherical, the particle size distribution of the microspheres is relatively uniform, and they can...

... metallographic microscope (Germany Leica Company DM1750m) was adopted to capture the micro morphology of MNS. Laser particle size analyzer (British Malvern Instruments Ltd Mastersizer3000) was adopted to test MNS particle size distribution. CT scanning experimental principle and devices are shown in Figs. 4...

... of a porous medium enhanced the heat transfer, whereas the presence of a hydrate promoter could enhance the mass transfer between the liquid-gas interface. In this study, we have studied the effect of sediment particle size and type of promoter on the kinetics of the methane hydrate formation and dissociation...

... to determine whether or not PPGs reduce the permeability of low-permeable rocks. Daqing (DQ) gel was used as a PPG sample for our filtration experiments. DQ is a strong gel particle with an elastic module of ~6500 Pa at 1% of NaCl (wt%). The particle sizes of the gel ranged from 30 to 120 meshes. Filtration...

... of polymer based drill-in fluids and dry bulk of sized calcium carbonate in terms of return permeability determination, change in particle size distribution, and weight loss. Results indicated that the generated acid mainly targeted fine particles of calcium carbonate present in drill-in fluids and dry bulk...
