Straight-Blade Stabilizer
Straight-blade stabilizers have straight vertical blades in the coaxial direction of the main stabilizer body or mandrel. The blades can either be integral to the stabilizer or on a replaceable sleeve. Straight blade stabilizers have less surface contact and wrap angle. They however provide fluid concentration with less probability of getting balled up while drilling sticky shale formations. Straight-blade stabilizers are mostly used in motor housing for sliding operations.
