Development and service of drilling fluid

The interval 320-2620 m was drilled with the utilization of the drilling mud with a low content of solid phase BRNSTF. In general, drilling of this interval was uncomplicated. The casing was set by one section. Multiple-stage cementing system was used. Drilling the well is carried out by the Chinese company Xinjiang Beiken Energy Engineering. Casing running and cementing jobs have performed without complications.
