WELL SCREENS Introduction A well screen is a filtering device that serves as the intake portion of wells constructed in unconsolidated or semi-consolidated aquifers. The screen permits water to enter the well from the saturated aquifer, prevents sediment from entering the well, and serves structurally to support the aquifer material.
This Water Source Stainless Steel Well Point penetrates all types of soil, delivering a combination of easy driving, effective sand control, corrosion resistance and strength. Three-step bonding method prevents screen from pulling back.
Oil & gas well and water well screen of wedge wire structure, fitted with slotted tubes / liners for well screen casing protection and support. Also known as V Slot Well Screen, Water Well Sand Filter or Well Screen Strainer. Cliclean also supplies Stainless Steel couplings, flange and other fittings for the complete SS well screens.
Excessive sediment concentrations in well water can be brought about by inadequate initial well development, absence of a well screen in a loose rock formation, oversized screen openings, excessive well screen entrance water velocities resulting from undersized openings, or well screen corrosion. Treatment of Pump Damage
Screen selection can have a far-reaching effect not only on the life of your downhole equipment and tubulars, but also on long-term well productivity and efficiency. From conventional to specialty sand screens such as our shunt-tube designs, our tailor-engineered solutions help you to increase tool longevity and achieve optimal production.
Well point screens are designed to keep large debris out of the groundwater, but in the process clay deposits gradually build up on these screens for diminished groundwater flow. To keep your well point unit operating, you need to periodically unclog well point screens.
Johnson Screens with its trade mark Vee-Wire ® is the leading brand for screens in industrial filters, water well and architecture. In 1904, Edward E. Johnson founded Johnson Screens after developing world's first continuous slot wire wrapped screen to be used in a water well.
If the top of the well screen pipe is at least 10 feet under the standing water level, just attach your pump to the top of the two inch well screen pipe. If the standing water level is lower, closer to the top of the well screen, then when you start pumping the standing water level will likely fall below the top of the well screen.
Jun 29, 2014· Three main causes for sand and sediment in drinking water wells. • Dissolved minerals: This is a common problem in well water throughout New Hampshire. Water hardness is a condition where calcium and magnesium dissolve into the well water, sometimes causing white or yellow sediment, especially within pipes and on water fixtures.
Sand control The water well screen is a key component of sand-control systems, either as an integral component of the gravel pack, or as a stand-alone provider of sand control. Johnson Screens well screens, with patented Vee-Wire® technology and welded construction, help to prevent screen failure by better controlling the sand.

However, these screens accumulate deposits from the water that passes through, slowly lowering your water pressure until it's completely clogged. To prevent this from happening, you must apply a chemical application that can reach the screen down in the well and eat away at the deposits, so the water can flow properly again.
When the pump turns on the water level in the well it can drop to a lower level. If the pump is down near the bottom of the well, sand and sediment can be sucked in. Other causes for sand in water can be that the well screen has become degraded and is allowing sand or sediment in from the gravel pack around the well screen.
If the well screen is not lined up with water bearing sand the well will still work fine. If other words, if you inadvertently place the well screen in a thick layer of clay, you will still have a functioning well! The water will go down from the water bearing sand through the gravel pack to the bottom of the well casing and then back up.

Hebei Shengkai Metal Mesh Co., Ltd. has enjoyed a high reputation among water well screen professionals covering water and oil exploration. Well screen is a key element of sand-control systems, either as an integral component of the gravel pack or as a stand-alone provider of sand control like pre-packed screen.
Other sources for sand in water may come from the well screen becoming degraded and then allowing sand or sediment in from the gravel pack around the well screen. When the well is drilled, it is lined with a steel, iron, or PVC plastic which is called a casing. The casing in the well shaft is installed by the well .

Red Flint Sand and Gravel well pack is specifically engineered for gravel packed wells. Engineering firms and well screen manufacturers specify Red Flint because of its superior chemical and physical properties. The gravel is used for in ground wells to form a barrier between the screens and the natural deposit of the soil formation.
screen refers to that structure in a well, which protects the borehole, but allows the entrance of water. In this sense, screen is a filter. The durability and efficiency* of a well depend to a large degree on its design, construction procedures and selection of casing and well screen. However, casings and screens alone comprise the principal ...
Well Casing and Screen. To keep loose sand and gravel from collapsing into the borehole, it is necessary to use well casing and screen. The screen supports the borehole walls while allowing water to enter the well; unslotted casing is placed above the screen to keep the rest of the borehole open and serve as a housing for pumping equipment.
