systems and methods for controlling deviations during drilling operations include securing a plurality of stabilizers to a lower portion of a drill string . the stabilizers can have a substantially triangular cross - sectional area oriented perpendicular to the longitudinal axis of the drill string , and a plurality of blades secured to the stabilizer at points associated with corners of the triangular cross - sectional area . the resulting system can exhibit improved stability and stiffness , an improved flow area , a reduced annular velocity , an increased penetration rate , and a longer usable life .
