Analysis of cases associated with occurrence of elastic behavior of subsurface rocks while estimation of wellbore stability

G.Sh. Asadova PhD in Tech. Sc. - Azerbaijan State University of Oil and Industry

Due to the generalization of the studies on the interaction of elastic behavior of subsurface rocks and carried out static analysis, the dependence of the speed of longitudinal waves on the subsurface rocks’ density has been obtained.

The dependence of Poisson coefficient on the lithologic features of the rocks has been specified.

The poor interaction by the well in a whole in the dependence of Poisson coefficient on the rock density is observed. Moreover, analogical dependences developed on the data of specific rocks are characterized with the closely connected correlation.
