Accumulation DownholeAccumulation in Surface EquipmentErosion of Downhole and Surface EquipmentCollapse of The FormationIf the production velocity in well tubulars is insufficient to transport sand to the surface, it will begin to fill the inside of the casing. Eventually, the producing interval may be completely covered with sand. In this case, the production rate will decline until the well becomes “sanded up” and production ceases. In situations like this, remedial operations are required to clean out the well and restore productivity. One cleanout technique is to run a “bailer” on a wireline to remove the
