This product is made from carefully selected high-quality fruit shells that are crushed and screened to create a natural granular plugging material. It is hard, tough, and available in a full range of particle sizes, allowing it to quickly bridge and fill leak layer gaps, efficiently sealing well leaks and stabilising well walls. At the same time, it optimises the mud cake, reduces fluid loss, and decreases friction resistance. It has stable chemical properties, is compatible with water-based and oil-based drilling fluids, is environmentally friendly and non-polluting, and is widely used for plugging fractures and leak-prone formations.
