better well development
Wedge wire screen made by wedge wire screen welding machines have very high open area, allowing better access to the entire formation around the screen. Fines and drilling fluid are removed quickly and completely, resulting in better well development.
lower pumping costs
The high open area of a wedge wire screen allows water to enter the well freely, resulting in minimal drawdown and less energy expended by the pump.
less maintenance
The continuous slot design allows lower entrance velocity of the water, which reduces encrustation rates. The slot design also resists plugging and prevents sand from damaging pumps.
careful design leads to successful screens
• Analyze the formation sand to correctly size the well screen
• A grade of steel with the right level of corrosion resistance is selected
• Noting the depth of the well, the correct combination of wire and rod that produces a screen with all the necessary strength characteristics is chosen
• The screen design is determined by aquifer characteristics and desired yield
sand control
The wedge wire 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.
