Shrouded metal mesh 3D sand screen

ALFA Fiber

AlfaFiber is a new generation sand screen, which is one of the most promising types of screens. Screens of this type consist of stainless steel wire fibers wound around the main pipe with a specified density, provide reliable control of sand removal under the most severe operating conditions. These are durable, reliable filters that do not require special equipment for run into the hole. Due to the volume 3D filtration, the screens create a low pressure drop, have a tortuous channel for reducing the fluid velocity and reducing erosion, which increases the life of the well. AlfaFiber shows excellent filtration rates over a wide range of conditions, reduces the risks of plugging wells even in situations of unknown granulometric composition of the dispersed fraction. Due to the large open inflow area, this type of sand screen can be successfully used for both high-viscosity oils and gas wells.
