Special bits

“BC” type bits

Small and medium diameter (45-250mm) bits are equipped with tungsten carbide inserts designed for drilling out liner equipment, cement and sand plugs, tubing cleaning from paraffin deposits and other operations.

Bits of big diameter (250-500 mm) are ideally suited for drilling sections for conductor and surface casing that are represented by low abrasive soft and medium rocks. The design provides welded blades equipped with carbide inserts and hardfacing.

“BR” type bits

These bits are designed for reaming, wiper tripping and gauging wellbores in low abrasive soft and medium rocks. The use of these bits allows avoiding premature failure of expensive PDC tools. Body profile and cutting structure prevent spontaneous sidetracking in trouble wellbore. Cutting structure represents the combination of PDC cutters and carbide inserts.

Gage basket “BK”

The use of gage basket allows combining wiper trip and logging excluding additional round trip operation thus reducing well construction time. Body profile together with PDC cutting structure allows reaming tight sections and smoothing wellbore walls. Design of the internal part of the basket provides unconstrained run of logging tools.ние геофизических приборов.
