●Integral Spiral Blade Stabilizer is designed to control hole deviation, prevent differential sticking and minimize dogleg severity and thus provide optimum drill bit's performance. It is devided into Integral 3-Spiral Blade Stabilizer, Integral 4-Spiral Blade Stabilizer. The unitized construction features three spiraled ribs designed to minimize downhole torque, reduce damage to the hole wall and ensure maximum fluid circulation. The IBS is well suited for use in most formations from soft and sticky to hard and abrasive. It is available in both bottom-hole and string designs, providing the flexibility to run it anywhere in the BHA.The Integral Blade Stabilizers manufactured from high-strength alloy steel as a single piece tool. Fully heat treated, their strength, hardness and impact strength are attained to standard.
