The FiberFrac technique involves injecting proppant and organic fibre into the fracture simultaneously, which stops the proppant from settling quickly into the hydrofrac liquid and helps to spread it evenly along the fracture. The organic material also improves the fracture’s conductivity and controls its height growth.
Schlumberger also produced results in April at other fields operated by the Nizhnevartovsk Oil and Gas Production Enterprise, with two successful standard hydrofrac operations at Pads Nos.4 and 5 at the Koshilskoe field. The wells are now back on stream, with a combined flow-rate of 68 tonnes per day instead of the anticipated 48 tonnes.
