APPLICATIONS:
- Heavy oil and Bitumen reservoirs, vertical and horizontal.
- Cyclic Steam Stimulation (CSS) wells – high steam pressures and temperatures.
- Steam Assisted Gravity Drainage (SAGD) Wells.
- Thin Pay Zones (3 meters minimum).
- Outflow and inflow control device.
FEATURES:
- Ports – designed to control steam outflow distribution and oil inflow volumes.
- Slotted Liner Outer Sliding Sleeve – independent to the inner tube, provides sand control.
- Hardened Blast Couplings – controls steam erosion to slotted liner outer sliding sleeve.
- High Torque-Sealed Connections – allows rotation of the STJ liner during installation.
- Wear Resistant Materials – working @ 350°C (662 oF) and 13,790 kPa (2,000PSI).
BENEFITS:
- Cost & Solution Effective Completion System – single string-dual completion.
- Optimal Steam Distribution – even steam distribution coupled with sand control for optimal production.
- Installation and Operational Loads – All tensile, compressive, and torsion loads to the STJ during installation and operations are subjected to the inner sleeve only.
- Sand Control – slotted liner outer sleeve capable of obtaining high open areas, due to extremely low installation and/or operational loads.
- STJ outside diameters equivalent to blank casing run in conjunction with the STJ’s.
- Zonal Isolation – each STJ is independently zoned to the area of formation it resides in.
