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.

Claim (Index 10):
A method of directional drilling comprising:\n steering a drill bit along a well path by operating a rotary steerable system having a control module enclosed within a non-rotating steerable housing; measuring a distance between the steerable housing and a distance to an approaching upper or lower formation boundary with azimuthal resistivity antennas disposed within the non-rotating steerable housing, the azimuthal resistivity antennas comprising: an axial antenna including a wire winding for generating an axial magnetic moment parallel with the longitudinal axis; and a transverse antenna including an antenna body having a longer axis disposed longitudinally in the housing, and a wire coil having a central axis disposed around the antenna body, wherein the wire coil central axis is substantially perpendicular to the longer axis of the antenna body, and wherein the wire coil is configured to generate a transverse magnetic moment orthogonal to the housing longitudinal axis; and steering the drill bit away from the approaching upper or lower formation boundary, based on the azimuthal resistivity measurements, to maintain a certain distance between the steerable housing and the approaching upper or lower boundary of the formation.
