IBS stabilizers are downhole tools installed in the drill string to provide stabilization and reduce vibrations during drilling. They help maintain the trajectory of the wellbore and prevent deviation. These stabilizers are designed with integral blades, which ensure durability, high wear resistance, and efficient performance in harsh drilling conditions.
________________________________________Sleeve stabilizers are stabilizing tools consisting of a replaceable sleeve mounted on the body of the tool. They are commonly used for directional control and maintaining gauge hole size. The advantage of this type is its cost-effectiveness and flexibility, since only the sleeve needs replacement after wear, while the body can be reused.
________________________________________Near-bit stabilizers are placed directly above the drill bit to provide immediate stabilization and support. They improve bit performance, enhance hole quality, and help in maintaining the planned wellbore trajectory. By minimizing vibration and ensuring smoother drilling, these stabilizers increase penetration rate and reduce premature wear of the bit.
________________________________________Core barrel stabilizers are special stabilizers used in coring operations. They are installed around the core barrel to centralize it in the hole and reduce vibration during coring. This type ensures a higher recovery rate of core samples and provides a smoother, more accurate wellbore while protecting both the core barrel and the bit.
