Prediction of penetration Rate and cost with Artificial Neural Network for Alhafaya Oil Field
Iraqi Journal of Chemical and Petroleum Engineering, 2018 Prediction of penetration rate (ROP) is important process in optimization of drilling due to its crucial role in lowering drilling operation costs. This process has complex nature due to too many interrelated factors that affected the rate of penetration,
