The johnson well screen is a critical component of sand-filtering equipment and an integral part of the gravel pack. Johnson well screens with advanced technology and welded construction help prevent screen failure by better controlling the sand. Johnson well screens have a very high open area, allowing better access to the entire stratum around the excellent screen. Particles and drilling fluid can be filtered quickly and completely, resulting in better well development.
Johnson well screen allows water to enter the well freely and reduce the pump's energy expended. The continuous slot design allows lower entrance velocity of the water, which lowers encrustation rates. The slot design also resists plugging and prevents sand from damaging pumps.
