Predicting of shear wave velocity using Artificial Neural Networks
Shear wave velocity is an important parameter for determining lithology, porosity and the dynamic properties in geo-mechanical studies. However, due to time and cost limitations, shear wave velocity is not available at all intervals and in all wells. In this paper, well logs with strong correlation to shear wave velocity were determined and used to predict the shear wave velocity for the Tano North Field. Four different methods were used to estimate the shear wave velocity under three different conditions. Then, based on obtained coefficient of determination and average absolute percent relative error between real and predicted values of shear wave velocity, the final results were compared. The results of this work demonstrated that the neural network based on multiple variables can estimate the shear wave velocity better than other methods used.
