Abstract
A rotary steerable system includes a non-rotating housing, azimuthal resistivity antennas and electronics, disposed within the non-rotating housing, configured to measure a distance to an approaching upper or lower formation boundary, and a control module configured to steer a drill bit along a well path and, based on measurements from the azimuthal resistivity antennas, to steer the housing away from the approaching upper or lower formation boundary and thereby maintain a certain distance between the steerable housing and upper or lower formation boundary.
