Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-0036
.... In such cases, empirical correlations are used to calculate the sonic transit times. But none of these empirical correlations are universally acceptable. As a result, inaccurate values can potentially raise major concerns throughout the life of the well. The objective of this paper is to develop a...

... and performing laboratory tests on them are extremely expensive as well as time consuming. Therefore, mostly UCS predicted from empirical correlations. Most of the empirical correlations for UCS prediction are based on elastic parameters or on compressional wave velocity. These correlations were...

... compressive strength (UCS) of carbonate rocks. The impact of the vugs on the stiffness of the material is also evaluated. The results are then compared with empirical correlations found in literature, which have been previously used to predict the UCS and stiffness of carbonate reservoirs. This study hopes to...

... behavior. While some empirical correlations between microscopic attributes (such as crack density) and mechanical parameters (such as stresses) are involved, the employment of micromechanical models has the potential of correctly reflecting the sensitivity of rock mechanical parameters to changes in...
