Jeonsure - Insert Premium Screens
Insert premium screens consist of Premium discs that are flush mounted and secured into the base pipe, thereby creating an economical screen that is significantly stronger than slotted liner and offers much greater open flow area (OFA). Insert premium screen’s cost-effective geometry provides significantly more torsion, compression, and collapse strength than slotted liner, which is crucial for horizontal wells, especially thermal wells such as SAGD. The standard cartridges (discs) are 1.0 inch (25.4 mm) diameter and 0.25 inches thick, and made of many layers of 316L stainless steel sintered mesh—all fusion bonded together to provide high permeability and strength. Smaller discs are available for thin-walled pipes.
The layup of weaves can be optimized for a given application. A wide range of micron ratings are available to optimize sand control and retained permeability.
- Has variable open flow area to match well productivity
- Has premium sintered mesh medium with ratings of 60 to 600 microns
- Is made with corrosion-resistant metal such as 316L
- Has excellent tensile, compressive, torsional, and collapse strength
- Can rotate, reciprocate, and circulate through difficult hole conditions
- Has excellent sand retention capability
- Can be treated just like casing, even drilled into place
- Horizontal wells with steam-assisted gravity drainage (SAGD)
- Robust alternative to slotted liner with higher OFA.
- Economical alternative to wire-wrapped and pre-pack screens
- Vertical or horizontal gravel-pack or frac-pack applications
- High-pressure, high-temperature wells
- Water/steam injectors and coalbed methane producers
- Underpressured or depleted wells
- Highly corrosive environments
