SHEAR WAVE VELOCITY MODELING BASED ON WELL LOGGING DATA; A CASE STUDY FOR ONE RESERVOIR IN ONE OF THE SOUTHWEST IRANIAN OIL FIELDS

Waves velocity are important parameters for determinate the dynamic modules magnitude in geomechanical studies. But, due to practices and cost limitations, shear wave velocity is not available in all wells. In this paper, it is trying to predict the shear wave velocity for one reservoir in one of the southwest Iranian oil fields from well log data, such as, compressional wave velocity, neutron porosity and density. Several methods were used to estimate the shear wave velocity. Then, based on obtained coefficient of determination and average absolute percent relative error between real and predicted values of shear wave velocity, final results compared together. The results of this work demonstrated that the obtained model from multiple linear regression method able to estimate the shear wave velocity better than other used methods.
