Gravel pack

A gravel pack is a method used in oil and gas wells to prevent the surrounding rock from collapsing or dirt from entering the well. It involves placing a screen in the well pipe and then filling the space outside the pipe with specially selected gravel. This gravel allows fluids like oil and gas to flow into the well while blocking larger particles like sand or rock that could clog or damage the system. Essentially, it’s a filtration system that keeps the well clean and stable, ensuring efficient extraction of resources and protecting equipment.
