In this chapter I describe how to predict pressure from the compaction state of mudrocks. The compaction state is either measured directly (e.g., from cuttings and core) or indirectly (e.g., from resistivity, velocity, or density). I present a detailed example from the Eugene Island 330 (EI-330) oil field, Gulf of Mexico. I then review two common challenges: (1) how to pick mudrocks and (2) how we establish normal compaction trends in overpressured basins. I close with a review and comparison of five different compaction models.
