Wedge Wire Pipe Based Well Screen for Oil Wells
Pipe-based sand screens combine a perforated API casing or tubing base with a welded V-wire jacket for controlled sand retention in oil and gas completions.
304L / 316L / Duplex Materials
Technical Overview
Construcción, materiales, and operating considerations
El Pipe-Based Wedge Wire Well Screen uses the base pipe as the structural member and the screen jacket as the filtration surface. The base pipe can be supplied in an API casing grade or in a stainless or duplex alloy, depending on the well design. Perforations provide the flow path between the screen jacket and the pipe bore, while the V-shaped wire controls the size of particles entering the completion. This arrangement is useful when a screen has to carry deployment loads as well as provide a defined filtration opening.
The wire jacket is resistance-welded at the contact points between the profile wire and the support rods. The welded construction keeps the slot pattern in place during handling and installation. For horizontal, desviado, and high-pressure wells, the load carried by the screen is primarily transferred through the base pipe and end connections, so the pipe grade and wall thickness need to be selected with the completion loads in mind.

Construction of a Pipe-Based Sand Screen
The screen is built around two main parts: a perforated base pipe and a continuous-slot wedge-wire jacket. The pipe carries the main tensile and collapse loads, while the jacket provides the sand-retention surface. The two parts are joined at the ends and, depending on the design, supported at intermediate locations.
1. Perforated Base Pipe
API 5CT casing or tubing can be drilled with CNC equipment using staggered, longitudinal, or other specified hole patterns. Hole diameter and density are selected to provide the required flow area without removing more pipe wall than the design permits. The finished holes are normally deburred before the screen jacket is fitted.
2. Wedge-Wire Jacket
The jacket is made by winding V-shaped profile wire around longitudinal support rods and welding the contact points. Because the slot is narrower at the outside surface and opens toward the inside, particles that enter the opening are less likely to become wedged in the slot.
3. End Rings and Collars
End rings or collars secure the screen jacket to the base pipe. Their dimensions and weld details depend on the connection design and the loads expected during running in hole (RIH), including handling, torque, and axial forces.

Manufacturing and Welding
Automated Resistance Welding of the Screen Jacket
Manufacturing starts with inspection of the base pipe and screen wire and continues through drilling, jacket forming, soldadura, assembly, end preparation, and final inspection. The exact sequence depends on the pipe size, material, slot opening, and connection required.
The base pipe is positioned on a CNC drilling machine and the specified hole pattern is produced around the pipe. Hole position and diameter are checked during production, and burrs are removed from the bore and outside surface so that they do not interfere with flow or screen assembly.
The V-wire is formed around the support rods while the winding pitch is controlled by the welding machine. Slot opening is checked against the purchase specification, and the wire-to-rod contacts are welded as the jacket is formed.
After welding, the jacket is fitted over the perforated base pipe. Where support rings are specified, they are installed at the required spacing to keep the jacket aligned with the pipe during handling and service.
End rings are welded to the base pipe and jacket using the welding procedure specified for the selected materials. The joint is intended to hold the jacket in position and limit flow bypass around the screen ends.

Aplicaciones de campo de fondo de pozo & Entornos de implementación
Typical Downhole Applications
Petróleo pesado & Recuperación Térmica (SAID)
SAGD and other thermal-recovery wells expose completion components to repeated heating and cooling. For these services, stainless or duplex screen materials may be considered where the temperature, fluid chemistry, and mechanical loads justify their use. The selected alloy and base pipe still need to be checked against the actual completion conditions.
Pozos profundos de hidrocarburos de alta presión
Deep wells can impose substantial collapse and tensile loads on the screen assembly. A heavier-wall L80, P110, or other specified base pipe can be selected when the calculated loads require it. Collapse resistance should be established from the actual pipe dimensions, calificación, connection and well conditions rather than from a single nominal pressure figure.
Pozos horizontales de alcance extendido
Horizontal completions can place the screen under drag, flexión, and side loads during running. A rigid base pipe helps carry these loads, while centralizers and the running procedure are used to control contact with the wellbore.

*Madera (Número equivalente de resistencia a las picaduras) = %CR + 3.3X(%Mes + 0.5x%W) + 16x%N.
End Connections and Thread Selection
The end connection is normally machined on the base pipe or supplied with the connection specified for the completion string. API Spec 5B connections or premium connections can be used, provided the thread, coupling, seal and joint strength are suitable for the planned loads.
An 8-round connection is commonly used where the casing design calls for this thread form and the expected joint loads are within its rated capacity.
Longer or premium connections may be selected when higher joint strength or improved sealing performance is required. The connection should be rated as a complete pipe-and-coupling assembly.
Buttress or other high-strength connection profiles are used when the completion design calls for greater axial load capacity. The choice should follow the casing program and connection manufacturer’s rating.

Slot Geometry and Flow Through the Screen
Why the V-Wire Slot Profile Is Used
Screen geometry affects pressure drop and the way formation fluids enter the completion. A conventional slotted liner has straight slot walls, so particles can lodge across the opening as the slot becomes restricted. Local velocity can then rise around the remaining open area, increasing the chance of uneven flow and wear.
En contraste, el Alambre perfilado en forma de V Presenta una abertura estrecha y precisa en la superficie exterior que se ensancha internamente hacia el tubo base.. Cualquier partícula de arena lo suficientemente pequeña como para pasar a través del borde exterior de la ranura fluye libremente a través del canal de ampliación interno sin atascarse.. Este diseño minimiza las caídas de presión en la sección de la pantalla., preserva la velocidad de entrada uniforme, y reduce la erosión.

Use with Gravel-Pack Completions
In formations with fine or poorly sorted sand, a pipe-based screen can be installed as the retaining element in an open-hole or cased-hole gravel-pack completion. The screen slot and gravel size are selected as a matched system rather than as separate items.
During gravel placement, the selected gravel is pumped into the annulus around the screen. The slot opening is chosen so the screen retains the gravel while allowing produced fluid to pass through. The base pipe carries the mechanical load during placement and subsequent production.

Packaging and Field Handling
Packaging for Transport
The screen jacket and end connections need protection during transport because dents, bent wires, and damaged threads can affect installation. Packaging is normally selected according to pipe length, weight, destination, and handling method.
Thread protectors are fitted to exposed pin and box ends where applicable. They help keep dirt and handling damage away from the connection surfaces.
The screen jacket can be wrapped and restrained with suitable protective material to reduce impact from adjacent pipes and lifting equipment during transport.
Depending on shipment size and destination, screens may be packed in treated wooden cases or bundled on steel frames. Spacers are used where necessary to keep adjacent screen surfaces from rubbing against each other.

BLOCK 25: Technical Installation Guidelines Block
Running the Screen into the Well
Handling and RIH Considerations
The screen should be handled in the same way as other precision completion equipment, with particular attention to the wire jacket and threaded ends. The completion program and the connection manufacturer’s running procedure take precedence over general handling advice.
Use suitable lifting slings and protectors, and keep elevator dies or slips from contacting the wire jacket directly. The screen surface should not be used as a lifting or gripping point.
Apply the specified thread compound to the connection surfaces in accordance with the casing running procedure. Keep excess compound away from the screen slots and verify makeup according to the connection specification.
Run the assembly at a controlled speed to limit surge effects. En pozos desviados, centralization and the planned RIH procedure can reduce contact between the screen and the low side of the hole.
