.... Viscosity was used to describe the slurry properties, while for the hardened cement samples, the elastic, petrophysical, and strength properties were described by the Poisson's ratio, permeability, and compressive strength, respectively. Moreover, the particles settling was measured by the density variation...

... ABSTRACT CO 2 -injection into depleted reservoirs can lead to rapid cooling and a CO 2 phase change in the near-wellbore region, potentially affecting rock mechanical integrity. We report unconfined compressive strength (UCS) and thick-walled cylinder (TWC) collapse strength tests on dry...

... strength of the cement were considerably increased with the increase in the olive waste content. The cement compressive strength was also increased with the incorporation of olive waste of a maximum of 0.375 %, and the permeability was decreasing with the addition of a maximum of 0.25 % olive waste...

... 6.2m/h. In this paper, a weight distribution model is established, which takes into account the compressive strength of the formation at both the reamer-rock interface and the pilot bit-rock interface. According to the model, it is suggested to adopt a structure design for the reamer with stronger...

... properties, compressive strength, and permeability of the cement sheath. Three different formulas of cement, base, graphite-based, and olive waste-based cement were used in this study. The result showed that the graphite and olive waste successfully increased the compressive strength by 106% and 110...

... of bottom hole confining pressure on deep/ultra-deep layers. Now, some studies have proved that confining pressure has an effect on rock mechanical properties. When the strain rate remains stable, the confining pressure can improve the compressive strength of rock. (Christensen et al, 1972;Hokka et al...
