The paper describes a new practical method of calculating dynamic fracture growth in multilayered reservoirs. The method predicts growth rate with time for a situation with two shale layers on each side of the centre (reservoir) layer. The static (equilibrium height) results are obtained as a limiting case at large times. Based on the numerical solutions, a correlation was developed which is computationally very efficient and can be implemented in any pseudo-3-D fracture simulator.

The examples of simulated fracture growth show the importance of even small barriers for temporary containment of fractures and the importance of the dynamic pressure effects as opposed to an equilibrium height model.
