Increasing rotary speed has a greater effect on increasing rate of penetration in Abu Dhabi shales and limestones than other drilling parameters, including various mechanical and hydraulic factors.
The graphical presentation of drilling parameters and penetration rate data found that rotary speed is the most important factor in controlling rate of penetration.
Constants for the penetration rate equations were developed from a least square analysis of empirical data. The formulas and design charts can hel...
