The product is a seamless sintered woven wire well screen assembly concentrically mounted on a perforated or slotted mandrel. The seamless sintered woven wire screen can either be used as a component screen apparatus or as a primary screen filter element. In use as a component screen application, the seamless sintered woven wire screen provides a filter reinforcement to a primary filter, or filter housing or shroud device that protects the component screen from physical or mechanical damage during installation. In this configuration two (2) usually different and separate filter devices are combined. In use as a primary screen element no other means other than the seamless woven wire screen is involved in prohibiting unconsolidated sand production from the wellbore. The well screen relates generally to completing downhole wells, and in particular to well screens for filtering unconsolidated material out of inflowing well fluid in water, oil, gas, and recovery wells. |
