An Estimation of Pore Pressure in Shales from Sonic Velocities

Pore pressure in shaly formations is difficult to measure due to their extremely low permeability. For this reason, indirect methods of pore pressure estimation in shales are crucially important. Overpressured zones in shales are currently identified by deviation of sonic log velocities from the vel...
