Method and system for formation pore pressure prediction prior to and during drilling

Abstract

A method for facilitating drilling of a prospect involves, for a multitude of offset wells associated with the prospect, obtaining offset well data, the offset well data including surface drilling parameters, mud gas data, and formation pore pressure data. The method further involves training, using the offset well data, a machine learning (ML) model to make formation pore pressure predictions, where the offset well data used for training the ML model excludes the offset well data of an offset well in closest proximity to the prospect. The method also involves generating a formation pore pressure profile prediction for the prospect prior to drilling the prospect by making formation pore pressure predictions for the offset well in closest proximity to the prospect using the ML model operating on the offset well data of the offset well in closest proximity to the prospect.
