Hybrid Fluid High-Rate Multistage Fracturing
Packer Service LLC applied a unique technology of hybrid multi-stage hydraulic fracturing on two horizontal wells.
The well completed 114mm liner with eight stages (total 16 stages with 130 t of proppant each). The design represented by a combination of a linear and a cross-linked hydraulic fracturing fluid system (linear system 50% of the total fluid). Pumping rate 10-12 m3/min. The fracture length over 500 meters.
One of the stages performed on a low-viscosity fluid system based on a friction reducer (polyacrylamide system) with improved anti-sedimentation properties a synthetic polymer with viscosity of 12-80 cp. During all pumping micro seismic recorded.
