A Rotary Steerable System (RSS) is a technology used in drilling operations to control the direction of the drill bit while it rotates. Unlike traditional methods that require stopping the drill to change direction, RSS allows for continuous rotation, improving efficiency and accuracy in reaching the target depth. This system is particularly useful in complex geological formations. The RSS consists of various components, including sensors and motors, that work together to adjust the angle of the drill bit. This capability enables operators to navigate around obstacles and follow specific paths, making it essential for projects in the oil and gas industry, as well as for geothermal drilling applications.
