Gravel packing screens, prepacked screens

We design to allow slurry to bypass sections that have bridged prematurely or become obstructed during gravel-pack operations. With multiple apertures located along the packing tubes in each screen, flow is redirected through the shunt tube system and the shunted screens more uniformly distribute the gravel or the slurry across the wellbore.

Enhanced Low Profile and Premium Low Profile Pre-packed Screens. screens can be used in gravel-packed and non-gravel packed wells. They incorporate a strong inner wire wrap layer made from round wire and a keystone-shaped outer wire wrap layer.

Pre-packed Screens ,When gravel packing is not feasible, pre-packed screens provide built-in sand control. They incorporate a keystone-shaped wire for the inner and outer wire wraps.

The pre-packed sand, typically resin coated and consolidated, can be provided in regular resieved sand varieties. All pre-packed screens are packed separately from the base pipe. This allows for inspection of the complete jacket for voids.

Pre-packed Screens — These screens can be used in gravel-packed and non-gravel packed wells. They incorporate a strong inner wire wrap layer made from round wire and a keystone-shaped outer wire wrap layer.

Pre-packed Screens — When gravel packing is not feasible, dual-screen pre-packed screens provide built-in sand control. They incorporate a keystone-shaped wire for the inner and outer wire wraps.
