The authors of the article consider the technology of drilling a casing section using drillable bits. The information on the equipment, its technical specifications, the procedure of its using and the technology application areas are presented. At least 30 % of standard and small-diameter wells have a vertical casing section. So, to reduce the construction cycle, an integrated approach to drilling the vertical casing section of 168, 178, and 245 mm casing strings using drillable bits is proposed. The technology prevents wellbore complications by simultaneous drilling and casing the borehole during the drilling process as well as drilling in the intervals with incompatible geological conditions. The authors of the article describe the method and means for this technology application, including drilling parameters, drilling modes for tooling and bits of various diameters, drill string bottom assembly and casing string extension methods. They also detail the sequence of process operations during wells preparation, drilling, and cementing. Cementing the casing string which was used for drilling a specific interval is one of the most important processes, which is described in detail. Cementing with a casing string rotation is also performed by a method different from the standard one, without a jacking plug. To promptly address complications and prevent accidents during a casing string drilling, a list of emergency situations and measures for their prevention is also presented. The conclusions include information on a range of costs that can be eliminated when drilling with a casing string.
