Rotary Steerables

摘要

As reservoirs are depleted, the necessity to drill directional wells to penetrate and access reserves is gaining momentum. Directionally drilled wells are increasing in complexity due to intricate wellbore trajectories, tighter zones, and challenging drilling mechanics. Application of rotary-steerable systems (RSS) in these wells improves penetration rates, borehole quality and turtuosity. Additionally, RSS tools will reduce high torque and drag and stick slip when compared to drilling directionally with mud motors. The decision to use RSS technology will result in longer sections drilled and wellbore evenness so that casing is optimally run.
