... permeability, compressive strength, Young’s modulus and stress-strain characteristics, were evaluated before and after high-temperature treatments. The results show that silica-modified cement can maintain reasonably high compressive strength and Young’s modulus after exposure to 550 C for 7 days. The use...

... ABSTRACT: A proper cementing job is an essential application in any successful drilling operation since it is heavily related to the well integrity. The cement quality performance used in this process is quantified by the cement compressive strength measured in three standard periods: 2, 7...

.... The spatial distribution of gravels can directly affect the mechanical properties of conglomerates. Specifically, the compression strength of gravels with a concentrated distribution of gravels (19.3 MPa) is 68.93% of the strength of gravels with a uniform distribution (28.0 MPa). The total damage energies...
