Annotation:

The paper presents the experience of using a borehole oscillator (a source for creating longitudinal vibrations of a drill string) at the Grekovskoye field in the Samara region. The oscillator has shown its effectiveness when drilling directional wells in the sliding mode, providing an increase of mechanical rate of penetration (ROP), which ultimately led to a reduction in well construction time, as well as to reduction of the risk of differential sticking. The paper discusses in detail the process of occurrence of the most typical complication of differential sticking at the fields of the Samara region.
