Multi-Stage Frac with Ball Drop system:
1. Multi-Stage Frac - allows to prevent a breakthrough of water;
2. Soluble balls instead of the usual (the first confirmed job with the dissolution balls in 2014г. at 10 stages in Russia);
3. Special coverage of the landing of saddles couplings for hydraulic fracturing allows to do a tonnage up to 20 frac stages.
Multi-Stage Frac Hardware «Omega»:
1. Full flow coupling with no restrictions of inside diameter. Full ID, can be used in cementing applications;
2. Mechanical activation using coiled tubing, tubing or tractor that allows for selectively fracturing, and also gives the possibility of overlap areas in the case of water breakthrough. Unlimited number of open/close operations;
3. Omega-Port can be used for both multistage fracturing operations, and for zone control of flow of wells in the extractive and in injection wells;
4. The design allows to combine Omega-Port with sand control filters and, if necessary, to control of each zone fiow rate.
