Drilling at Kola SG-3 began on 24 May 1970 using the Uralmash-4E, a serial drilling rig used for drilling oil wells. The rig was slightly modified to be able to reach a 7,000-metre (23,000 ft) depth. In 1974, the new purpose-built Uralmash-15000 drilling rig was installed onsite, named after the new target depth, set at 15,000 metres (49,000 ft). On 6 June 1979, the world depth record then held b.

The hydrostatic pressure of the drilling fluidis essential in maintaining control of a well and preventing blowouts. In a practical sense, it is defined as. .
Drilling operations often involve several fluid densities, pressure from fluid circulation, and perhaps applied surface pressure during kick control. .
The drilling fluid types provide a beneficial effect relative to drill string weight or hook load. The mud system supports or buys some of the pipe weight when the drill pipe is lowered into the well. This effect is termed buoyancyor buoyant forces. The buoyed weight of the drill string will be less than the in-air weight of the pipe. In drilling h. [pdf]
