چکیده
The lack of good knowledge about geomechanical parameters can be a big challenge in drilling new oil and gas wells or stimulating existing ones since geomechanical parameters are needed for safe and stable drilling. In this work, elastic parameters were determined from well logs using empirical correlations. The software used were Schlumberger Petrel 2017 and Microsoft excel 2016. The elastic parameters determined include seismic velocity ratio (Vp/Vs), shear modulus, bulk modulus, Poison’s ratio, Young’s modulus, acoustic impedance, shear impedance, Lamda-Rho and Mu-Rho. The results of the elastic properties obtained from well logs were then integrated into a 3D geomechanical model to generate the spatial and depth distribution of the properties in the study area. The obtained results showed that the velocity ratio varies between 1.00 to 3.25, shear modulus varies between 1.00 GPa to 3.35 GPa, bulk modulus varies between 7.5 GPa to 13.0 GPa, Poisson’s ratio varies between 0.20 to 0.48 and Young’s modulus varies between 0.50 GPa to 5.0 GPa. The spatial distribution of the properties revealed potential areas for drilling new wells, targeting the southern and the eastern portions of the area that are still undrilled. The results of this study coupled with the required rock physics and geomechanical information are of great importance for drilling or hydraulic fracturing of wells in this portion of the Rio Del Ray Basin.
