Abstract:
A multi-indenter drill bit includes a plurality of indenters arranged on a drilling surface of a bit face. The ratio of the total indenter area to the bit face area is defined by a parameter KPI1 (expressed as a percentage), and the ratio of the average individual indenter area to the bit face area is defined by a parameter KPI2, (expressed as a percentage). The relationship between KPI1 and KPI2 is defined by an equation.
