Claim One:
1. A method for predicting formation pore pressure, comprising: generating a borehole temperature model by calculating estimated borehole temperatures for an area of interest using water depth information and a vertical stress model; generating a formation temperature model by calculating estimated formation temperatures for the area of interest using the estimated borehole temperatures of the borehole temperature model; generating a mud-weight pressure model by calculating mud-weight pressures for the area of interest using the formation temperatures of the formation temperature model and pressure coefficients; generating a formation pore pressure model by calculating formation pore pressures for the area of interest using the mud-weight pressures of the mud-weight pressure model; and obtaining, using a processor, a proposed well plan based on the formation pore pressure model, wherein the proposed well plan is used to perform an oilfield operation.
