- •
A MSE model for rotating drilling with PDM is established.
- •
A method for real time optimizing drilling parameters for rotating drilling with PDM is presented.
- •
The new MSE model estimates MSE values with a reasonable approximation.
- •
The optimum WOB is low for rotating drilling with PDM, increasing WOB does not always increase ROP.
- •
The method can real time estimate optimum WOB with varying RPM to drill a specific formation with PDM.
