Answer:
Erosion Drilling is the process by which materials are worn or removed during drilling. In drilling techniques of oil and gas industries, erosion is important as it can lead to an increase in time and cost of operation. When solid particles impact a solid surface, it leads to erosion that helps the engineers to drill the rock formation. Erosion bit of earth drilling operations consists of two nozzles; the first one is open for drilling fluid while the other is closed by means of pressure sensitive closure. The three important factors that govern erosion drilling are erosive particles, angle of impact and type of material.
