Real-Time Pore and Fracture Pressure Prediction With FEWD in the Nile Delta

Predicting pore and fracture pressures while drilling is essential for optimal mud weight and casing point selection. In the Nile Delta, offshore Egypt, rapid sediment deposition has resulted in high overpressures which produce difficult drilling conditions. Traditional pore and fracture pressure prediction methods which use drilling data have recently been supported by a effective-stress method. This method uses FEWD data to measure formation properties directly and has helped the Operator to reduce drilling costs and the number of well sidetracks caused by drilling problems.
