The formation shear-wave (S-wave)’s velocity information around a borehole is of great importance in evaluating stability, reflecting fluid invasion, and selecting perforation positions. Dipole acoustic logging an effective method for determining S-wave’s radial profile the borehole. Currently, radial-profile inversion methods are mainly based on impacts changes formations outside dispersion ch...
For example, a scholarly follower of the Great Man theory would be likely to study the Second World War by focusing on the big personalities of the conflict – Sir Winston Churchill, Franklin Delano Roosevelt, Joseph Stalin, Charles de Gaulle (Allies); Adolf Hitler, Benito Mussolini, (Axis); et al. – and view all of the historical events as being tied directly to their own individual decisions a...
