The drill-off test for any oilfield drilling bits determines the optimum weight on bit and overall bit performance. A given amount of weight is put on the bit, and the draw works brakeis. .
The penetration rate that can be achieved by a bit has an inverse effect on the drilling cost per foot. The main factors that affect the penetration rate are 1. bit type 2. formation properties 3. drilling fluid properties 4. bit weight and rotary speed 5. bit hydraulics
