Predrill pore-pressure prediction using 4-C seismic data

摘要

Knowledge of formation pore pressure is important for the successful exploration and production of hydrocarbons. During exploration, knowledge of formation pore pressure allows the hydraulic connectivity and fluid migration pathways in a region to be assessed. Thus, an increase in pore pressure below a seismic horizon may indicate the presence of a seal, while different pore pressures either side of a.fault may suggest that the fault forms a barrier to flow.
