Abstract

The introduction of positive-displacement steerable motors in directional drilling practice offers better directional control in comparison with earlier used directional drilling systems and makes directional drilling widely accepted technology. But some disadvantages of the technology as drilling the curved parts of the wellbores in sliding mode and hole cleaning connected problems, demand further development of directional drilling systems. That results in rotary steerable systems development introduced in the practice in the late 1990s. Systems enable continuous rotation of the drillstring during drilling and more efficient transfer of weight to the bit. That results in higher rate of penetration and improved hole cleaning. Application of the rotary steerable system in a hole drilling in the Adriatic Sea area in Croatia as well as characteristics of the system and results of the application will be presented in the paper.
