AlfaSelect
Description
AlfaSelect is a multipurpose assembly device based on the use of a combination of multistage frac completion technology, fluid filtration from solid impurities and control of zonal inflow in an oil well.
AlfaSelect includes an assembly of SSD sand screens AlfaPort, frac ports and isolating packers. An important feature of this device is the use of one tool that is lowered into the well to switch the AlfaPort sleeve and control the hydraulic fracturing sleeve.
Characteristics
- It is possible to use various modifications of AlfaSelect device components
- It is allowed to use fittings of different diameters to change the throughput of the device
- Isolation of casing intervals using packers in case of flooding
- Zonal inflow control with shift collar port configuration maximizes horizontal well interval productivity
- Re-fracturing through the hydraulic fracturing sleeve
- Carrying-out hydraulic fracturing without milling additional windows
- Anti-corrosive materials with high resistance to aggressive environments
Usage
Advantages
- Protection of proppant removal after hydraulic fracturing operations
- Increased turnaround time for ESP pumps and submersible equipment
- Maximizing fluid productivity and recovery
- Equalizng SSD system
- Possibility of re-fracturing
- Elimination of zonal gas and water breakthrough
