Pre-packed Screens
The pre-packed sand control screen is used in wells where conventional gravel packing is not feasible or economical. There are 2 kinds of media provided, gravel and glass beads, HD Well Screen offers special pre-pack screen designs to suit your sand control needs
Pre-packed screens are an effective solution for keeping formation sand in its place. Gravel packing is used in conjunction with hydraulic fracturing but at much lower pressures. The formation sand is produced from the breakdown of formations where wells are located. This occurs particularly in formations made of sandstone, limestone, and other similar types of rock. The main goal of gravel packed is to stabilize the formation and maintain good productivity.
Pre-packed sand control screens are designed using an inner and outer slip-on wire wrap jacket screen of differing diameters which are secured together over a perforated base pipe. The thickness and size of the medium filter layer depend on the well requirements, such as formation size, flow rate, borehole size, etc.
The gravel sand or glass beads /quartz sand or ceramic or other proppant types medium filter is packed utilizing industrial vibrating machines to ensure a void-free pack and is then inspected utilizing high-intensity light from the I.D. of the pipe to ensure proper compaction and distribution. The pre-packed assemblies can be manufactured to any desired coverage ratio on the pipe to work in coordination with rig pipe handling arms or to space out to cover specific zones within a reservoir.
*multiple metal types, wire profiles, and filter media available. As well as, extremely damage resistant.
*304L/316L stainless steel rib and wrap wires for optimized corrosion and plugging resistance
*wedge wire wrapped for optimized sand retention
*the gravel pack material provides excellent compaction properties with high permeability for maximum flow characteristics.
*best in the upper part of a vertical well and in horizontal wells
HD Well Screen offers several prepacked screen designs to suit your sand control needs. All pre-packed well screens are packed separately from the base pipe, which allows for inspection of the complete jacket for voids.
