In this research we studied tricone drill bits by applying a
mathematical model which gives an analysis the effected factors on
its performance and efficiency(rate of penetration) , so we can
change these factors in valid allowable rang of operati
ng once ,
which it gives a positive impact on its performance which shorten
time and cost of drilling run , that has been in one of the Syrian oil
fields :Deir Ezzour petroleum company ..
