Product Description
OASIS Pre-Packed Sand Control Screens: Engineered for Reliability and Performance
OASIS specializes in the design and manufacturing of high-quality pre-packed sand control screens, built with precision and durability for oil, gas, and water well applications. With over a decade of expertise in stainless steel filtration screens and components, our products are trusted for their superior performance and longevity.
Our pre-packed screens consist of an inner and outer wire-wrapped jacket securely mounted over a perforated base pipe. The filter medium thickness and size are customized based on specific well conditions, including formation characteristics, flow rates, and borehole dimensions.
Ideal for stand-alone sand control applications, OASIS pre-packed screens offer an advanced alternative to conventional wire-wrapped screens. The integrated gravel pack layer provides exceptional sand retention without the need for external gravel placement—making them especially effective in challenging formations where traditional methods may fail.
These screens effectively prevent formation sand migration, helping to stabilize the wellbore and maintain optimal production rates. They are commonly used in sandstone, limestone, and other unconsolidated formations, often in conjunction with low-pressure hydraulic fracturing operations.
The filter media—whether gravel, quartz sand, ceramic, or other proppants—are densely packed using industrial vibrating equipment to eliminate voids. Each assembly is rigorously inspected under high-intensity light to ensure uniform compaction and distribution. OASIS pre-packed screens can be customized to any coverage ratio to align with rig pipe handling systems or target specific reservoir zones.
Construction
The typical OASIS pre-packed screen includes six layers (from outer to inner):
Outer screen
Outer support rod
Pre-packed gravel layer
Inner screen
Inner support rods
Perforated base pipe
This dual-screen design features two wire-wrapped jackets with a resin- or ceramic-coated silica sand fill in between. The wire gauge and sand size are selected based on formation particle size distribution to ensure optimal filtration.
Materials
We fabricate our screens using premium materials including stainless steel 304, 316L, low carbon steel, and special alloys such as Monel 400. All materials can be tailored to meet specific environmental and operational requirements.
