On the influence of mineral composition of mudstones of the Razvedochninskaya Formation of the Talibskoye field on well wall stability
Abstract
Borehole penetration of mudstones of the Exploration Formation of the Talnakhskoye field is often complicated by collapse of borehole walls. The strong tectonic disturbance of the area and high rock pressure due to the great depth (2000 m) of the formation do not fully explain this phenomenon, since both emergency and accident-free wells have been recorded in equal conditions ...
