Predrill pressure prediction has historically been done using very simple models and overly simplistic estimates of the earth's velocity field. The methods usually incorporate a locally calibrated set of curves for pressure. The advent of the effective stress concept and pressure prediction methods that developed from that concept have led to a much-needed inclusion of fundamental physics into the art of pressure prediction. The use of effective stress methods has become the standard for pressure prediction. This technique has many variants including the Eaton method, the Bowers method, and the Sperry Sun method.
