Downhole sand control solutions

​Sand control equipment portfolio includes conventional sand screens and advanced flow control technologies that help operators manage sand production and maintain optimal well performance. Some of the commonly used sand control equipment by our clients:

​

Conventional sand screens

• Standard wire-wrapped screens

A perforated pipe with a helical wire wrapped around it to create filtration slots of varying sizes. The wire-wrapped design provides mechanical strength and offers a larger filtration surface area. The screen’s slots allow fluid and hydrocarbons to pass while filtering out sand particles. The equipment is simple, reliable, and commonly used in unconsolidated reservoirs. Equipment is widely applied in both vertical and horizontal wells with moderate sand production.

​

• Premium mesh screens (PMC)

They use woven metal mesh or synthetic polymer mesh combined with a base pipe (typically a perforated steel pipe) to provide precise filtration of sand and other fine particles.

​

• Slotted liners

A perforated or slotted steel pipe that acts as a sand screen. The slotted liner has longitudinal slots that filter sand while allowing fluids to pass through. The size of the slots is typically selected based on the expected grain size of the formation. This type of sand screen is simple and cost-effective for relatively clean reservoirs with low to moderate sand production. Application of this equipment is commonly used in shallow wells or reservoirs with minimal sand production.

​

• Pre-pack systems

A sand control method that involves placing a layer of gravel or sand around the wellbore, which is then filtered through a screen. The gravel pack serves as a physical barrier to sand production. The screen keeps the gravel in place while allowing oil or gas to flow through. It is effective in preventing sand influx and providing excellent filtration. This equipment typically used in wells with unconsolidated formations where sand production is a significant issue.

Innovative/Advanced sand screens

• Expandable sand screens

These sand screens expand once in place, designed to better conform to the wellbore shape. Expansion also ensures optimal sealing against the formation and minimizing sand production. Equipment has high flexibility, corrosion resistance, and adaptability to wellbore changes and commonly used in horizontal and deviated wells, offshore wells, and wells with varying formation pressures.

​

• Composite screens

Made from advanced composite materials such as fiberglass, carbon fibre, or specialized polymers. Composite screens are designed to offer high strength-to-weight ratios, corrosion resistance, and flexibility. Some incorporate self-cleaning features or are pre-packed with gravel. Equipment is lightweight, resistant to corrosion (ideal for offshore and deep-water environments), and durable

Custom solutions

• Ceramic and boronized custom-engineered screens are based on specific well conditions

 

1. Ceramic Sand Screens:

Ceramic sand screens are made from advanced ceramic materials, which offer superior hardness, wear resistance, and thermal stability compared to traditional metal or composite screens. These screens are typically custom-engineered for each well based on factors like formation characteristics, pressure, temperature, and sand production levels.

​

2. Boronized Sand Screens:

Boronization is a process that involves infusing the surface of a metal or composite material with boron, creating a hard, wear-resistant layer. The process significantly enhances the hardness and abrasion resistance of the screen surface, making it highly effective at preventing erosion caused by sand production.
