Sammendrag
A total of six techniques are developed to model ROP for a new well. The techniques attain coefficients or specific values from a close-by already drilled well. Using these and drilling parameters, the proposed method predicts ROP for the new well. The techniques are mainly developed and influenced by Bourgoyne & Young’s model, d-exponent model and MSE model.
The techniques are tested by comparison with six wells; three close-by wells from the Ormen Lange field, and three close-by wells from the Morvin field. Thereby each well may be tested with each technique with coefficients or values from two different close-by wells. The results display both the actual ROP and modelled ROP plots for comparison. In order to thoroughly assess the validity of the techniques an analysis of the results is also performed.
