Soil conditions are key to Drilling Methods
Feb 21, 2017

Soil conditions will generally determine the most efficient drilling method. When mud drilling, pushdown—also called pulldown or weight on the bit (WOB)—is key. The harder the formation, the more pushdown required. As more drill pipe is added to the drill string, more weight is applied to the bit and therefore less pushdown is required from the rig.
