Continuous inclination, azimuth measurement optimizes RSS control

摘要

When they were introduced in the mid-1990s, rotary steerable systems (RSS) represented a step-change in directional drilling. Over the years, continued advances have expanded the operating window of RSS. As the drilling industry moves toward greater automation, RSS has been further enhanced with the capability for automated steering in tangent sections, including the vertical and lateral sections. The new downhole steering and measurement algorithms are taking RSS to the next level in steering capability and downhole survey methods. Field tests in US shale plays shown improved efficiency.
