Erosion. Erosion is a loss of original material due to solid particle impact on the material surface. Erosion is normally expressed as a rate of metal loss, usually mm/year. It usually occurs in turns or protrusions; or with solids content. Erosion, physical process in which soil, rock, and other surface material are removed from one location and transported to another. Erosion will often occur after rock has been disintegrated or altered through weathering.

Under aggressive operating conditions, flow velocity limits and thus the production limits are set to avoid erosion. and gas production. The fluids to induce erosion-corrosion may be single phase like the portable water or multiphase flows such as various combinations of gas, oil, water, and solid particles in petroleum industry [8]. It is well known that the turbulent flow, fluctuating shear stress, and Erosion has been long recognised as a potential source of problems in oil and gas production systems. It refers to the loss of materials on internal surface of various parts of a production system due to production fluid mixture (especially with sand) that impacting the inner surface at an angle and typically at high velocity. Components and pipe systems upstream of the primary separators carry multiphase mixtures of gas, liquid, and particulates and are consequently more likely to suffer from particulate erosion, erosion-corrosion, and droplet erosion.

It is usually difficult to erode the wellbore wall significantly with drilling mud alone due to its relatively low velocity and high viscosity .

It is seen that the contributions of corrosion and erosion to erosion- corrosion rate rank approximately 30% and 70%, Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock’s chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation. The negative effects of corrosion and erosion cost the oil & gas and power generation industries billions of dollars every year in unscheduled plant or pipeline shutdowns, inefficient or lost production, high maintenance repair costs or imposed fines. Experts believe that 20% to 25% of corrosion-related costs could be avoided. = gas density, lb/ft3. API RP 14E (1984) suggested C=100 for continuous and 125 for non continuous service.
