Wellbore instability is reported frequently as one of the most significant incidents during
drilling operations. Analysis of wellbore instability includes estimation of formation …

Sometimes engineers need to estimate the wet-rock P-wave velocity from the dry-rock P-
wave velocity. An estimation equation embracing all rock classes will be useful for the rock …

Engineers and researchers need to estimate the mechanical properties of rocks from P-
wave velocity. In previous studies, the researchers have investigated either the limited …

Uniaxial compressive strength (UCS) of an intact rock is an important geotechnical
parameter for engineering applications. Using standard laboratory tests to determine UCS is …

The experimental work described in this paper was carried out in order to discover about the
effects of petrographic characteristics on the ultrasonic pulse velocity and dynamic elastic …

The investigation of the physical and mechanical properties of stones in monuments needs
nondestructive methods and small quantity of testing material. In this framework, P & S …

The quality of large rock blocks produced from quarries depends significantly on the
fractures and the extent to which they penetrate into the rock. The paper reports a laboratory …

abstract Geological storage of acid gas has been identified as a promising approach to
reduce atmospheric carbon dioxide (CO2), hydrogen sulfide (H2S) and alleviate public …

Sulfate rocks are one of the problematic rocks that have always caused many problems
during or after construction of infrastructures. In this research, by sampling of Gachsaran …
