Dynamic Properties

Using Well Logs Data to Estimate Dynamic Elastic Properties of Carbonate Formation (Published)

Dynamic elastic properties are derived from the measurement of elastic wave velocities in the carbonate rock texture. Sonic logs provide the data of compressional velocity and shear wave velocity, which are used to calculate values of dynamic elastic properties. Five wells in Nasiriya oil field is the studied wells, the study made across the Mishrif and Yamamma carbonates formation. The NeuraLog software was used to digitize the scanned copies of available sonic logs, which are used as input data for the Interactive Petrophysics software. Compressional and shear wave velocities had been calculated from logs data. In this study, Poisson’s Ratio, Bulk Modulus, Young Model, and Biot’s constant are determined using the Interactive Petrophysics software. The results show that the compressional to shear wave velocity ratio (Vp/Vs) is ranged from 1.866 to 1.905, Poisson’s ratio values are varied from 0.252 to 0.309, whereas bulk modulus is ranged between 24.75GPa and 66.56Gpa. Y oung model values are varied from 29.98GPa to 75.32GPa, while Biot’s constant is ranged between 0.766 and 0.889.
