Near-bit stabilizer

Big Bear Near-Bit Stabilizer. Granular tungsten carbide hardfacing. (Servco)... [Pg.825]

Torsional vibrations are due to the stick-slip effect of the stabilizers in deviated boreholes. They can be seen at surface as large torque oscillations with a period of 3 to 10 s. Figure 4-308 shows a near-bit stabilizer in a deviated borehole. The stick-slip effect increases with WOB and RPM. [Pg.1020]
