Abstract

The object of the invention is to solve the problem of casing and string collapse of production or injection wells, which occurs due to cooling caused by injection of completion fluids into the well, by applying heat to the fluid being injected during operations, such as acid treatments, secondary recovery, scale removal, and inhibiting squeeze. The fluid laser heating equipment was designed to perform the heating of the fluid to be injected into a production or injection well. Before being pumped into the well, the fluid passes through the heating equipment, through a metal coil-shaped tube immersed in hot water, placed inside a tank, a laser system heats the water inside the tank, the water inside the tank exchanges heat with the coil heating the same, and in turn the coil exchanges heat with the fluid passing within it. In this way, the fluid will be at an appropriate temperature for injection into the well.
