Product Description
Our factory-built Gravel Prepacked Well Screens are the industry-trusted all-in-one sand control solution for oil
& gas, water well, geothermal, and CBM operations.
Purpose-engineered for unconsolidated, high-sand formations and
horizontal/deviated wellbores, each unit integrates three core
components: a high-strength perforated base pipe, a continuous
wire-wrapped outer screen, and a uniformly compacted, hermetically
sealed gravel filter layer between them. This multi-stage
filtration system delivers superior fine sand retention, minimizes
sand production, reduces downhole pressure drop, and eliminates the
cost, complexity, and placement risks of on-site gravel packing.
Technical Specifications
All units comply with API 5CT, and ISO standards, with full custom
engineering available for your well requirements.

Key Advantages
- Superior Fine Sand Retention: Multi-stage filtration locks in formation fines, ideal for
unconsolidated high-sand reservoirs, eliminating sand-related
equipment damage and production loss
- Lower Operational Costs: Factory-preassembled design cuts rig time by up to 70%,
eliminates on-site gravel pumping services, and reduces costly
workover interventions
- Optimized Production Performance: Uniform gravel pack and precision slot design minimize pressure
drop, maintain balanced inflow, and preserve peak well productivity
long-term
- Broad Well Compatibility: Perfect for horizontal, deviated, and vertical wells, with full
adaptability for oil & gas, water well, geothermal, and CBM
applications
- API Compliant Durability: Built to industry standards with corrosion-resistant alloy
options, delivering reliable performance in H2S/CO2, high-chloride,
and HPHT downhole environments
- Guaranteed Consistent Performance: 100% factory-tested before shipment, eliminating the placement
risks and variability of field gravel packing
Quality Inspection
All our Gravel Prepacked Well Screens are manufactured under ISO
9001 quality management systems, with a strict multi-stage
inspection protocol:
- Raw material certification with full MTR verification for all
incoming steel and gravel media
- 100% dimensional and visual inspection, including precision slot
tolerance validation
- Non-destructive testing (NDT) for all welds, including liquid
penetrant and ultrasonic testing
- Hydrostatic pressure testing for every completed screen assembly,
per API standards
- Gravel pack uniformity and compaction validation to eliminate voids
and channeling risks
Frequently Asked Questions (FAQ)
Q: What formations are gravel prepacked well screens best for?
A: They are purpose-built for unconsolidated, high-sand, and weakly
consolidated formations, and are the optimal sand control solution
for horizontal and highly deviated wellbores where field gravel
packing is not feasible.
Q: What’s the difference between prepacked well screens and on-site
gravel packing?
A: Factory-prepacked screens come with a fully sealed, uniformly
compacted gravel layer, 100% tested before shipment. This
eliminates the high costs, rig time, and placement risks
(channeling, incomplete packing) of on-site gravel pumping
operations.
Q: Are your screens API compliant?
A: Yes. All our gravel prepacked well screens are manufactured to
meet API SPEC 19SS, API 5CT, API RP 19E, and ISO 17824
international standards, with full documentation provided with
every shipment.
Q: Can you customize screens for my specific well?
A: Absolutely. We offer full custom engineering, including tailored
gravel mesh sizes, slot openings, material grades, dimensions, and
end connections, based on your formation sand analysis and well
design.
Q: What applications can these screens be used for?
A: Our prepacked sand control screens are widely used in oil & gas
production wells, water wells, geothermal wells, coal bed methane
(CBM) wells, and injection wells across the globe.
