The paper describes an experience in the field of slant directional drilling in oil industry, which is currently under pressure. The experience helping to meet drilling projects’ challenges in an effective way has been approved for a several years of work at quite a few projects in different countries. The paper includes some design and technological tricks to overcome standard problems arising during slant directional drilling of oil wells such as entering the ground, maintaining the drilling trajectory, adjusting of an axis misalignment between the rig’s central shaft and the drill line, choosing proper pumps and adjusting pumping pressure, and keeping the drill rods and casings from sliding into the hole from an inclined mast.
