Cotton Sand Socks (50 Micron) | Ultra-Fine Flowback Filtration & Polishing

The 50-Micron Cotton Sand Sock is an ultra-fine filtration consumable designed for the absolute highest level of particulate removal in oilfield flowback, well testing, and produced water management. At 50 microns, it captures microscopic silt, clay particles, and ultra-fine proppant dust that pass through primary sand separators and standard 100-micron or 200-micron filters. Leaving these micro-abrasives in the fluid stream can cause severe, insidious wear on the internal components of high-pressure injection pumps and sensitive flowmeter instrumentation.

A distinct advantage of the industrial cotton construction is its natural affinity for hydrocarbons. While the tightly woven 50-micron pores mechanically trap microscopic solid particulates, the cotton fibers simultaneously work to absorb and strip trace oils, greases, and sheen from the water stream. This makes the 50-micron cotton sand sock the ultimate polishing filter prior to fluid entering Saltwater Disposal (SWD) injection pumps, ensuring that sensitive disposal formations remain unplugged and permeable.

Constructed for high-pressure oilfield environments, these filter socks feature heavy-duty reinforced stitching to withstand the high differential pressures associated with ultra-fine filtration. By delivering a pristine, meticulously polished fluid stream, these sand socks significantly extend the operational lifespan of your critical downstream processing equipment and injection wells.

Features & Benefits

• 50-Micron Ultra-Fine Filtration: Tightly woven to capture microscopic silt, clay, and pulverized frac sand for maximum fluid clarity.

• Trace Oil Absorption: The natural cotton fibers actively absorb trace hydrocarbons, oils, and sheen from the fluid stream, providing superior water polishing capabilities.

• Ultimate Tertiary Sand Control: Ideal for final-stage deployment downstream of primary bulk sand separators to ensure absolute fluid clarity before disposal or reinjection.

• Heavy-Duty Reinforced Seams: Manufactured with rugged stitching designed to survive high differential pressures without rupturing as the ultra-fine pores load with silt.

• SWD Formation Protection: Prevents micro-silt and trace oils from plugging disposal well formations, reducing injection pressures and maintenance costs.

Specifications & Technical Details

Applications

50-Micron Cotton Sand Socks are primarily utilized in the final polishing stages of well flowback or as a tertiary filtration step downstream of coarser 200-micron or 100-micron filters. They are heavily deployed in Saltwater Disposal (SWD) facilities and enhanced oil recovery (EOR) operations to polish produced water, ensuring that injection wells do not suffer from formation damage caused by microscopic silt or trace oils.

Quality Assurance

Every batch of our 50-micron cotton sand socks undergoes rigorous quality control. The cotton media is verified for highly consistent micron density, and all seams are stress-tested to guarantee they will not fail under the heavy loading and high pressure differentials typical of continuous oilfield fluid processing.
