Small-Particle-Size Cement | SPE Production & Operations ...

The particle size of Class G oilwell cement is responsible for its limiteduse in specific remedial cementing operations. Because the largest particles ina typical Class G cement are in the 100- to 150- range, cement slurries willnot penetrate fractures narrower than about 0.4 mm or sandpacks finer thanabout 10/20 mesh.

Jun 17, 2019 · When cement composition is constant, the residue and the SSA can be used as a guide to identify changes in psd. For example, the table below shows the estimated slope of the Rosin-Rammler psd from the SSA (in m 2 /kg) and the residue (at 45μm). The slope is based on the particle size data obtained by x-ray sedimentation.
