Gravel Packing
Gravel packing is a sand-control method used to prevent the production of formation sand. Gravel packing is used in conjunction with hydraulic fracturing, but at much lower pressures. Formation sand is produced from the breakdown of formations where wells are located. This occurs particularly in formations made of sandstone, limestone, and
