Abstract
The present disclosure describes various antenna assemblies, each antenna coil being disposed about a tool body section in an antenna pathway. The antenna pathway passes through alternating grooves and lands. At least one of the grooves is disposed in the tool body section at a non-axial direction relative to the longitudinal axis of the tool body section. The antenna coil may be an axial coil or a tilted coil. Additional grooves oriented at axial direction may be disposed on the tool body section. Various methods include acquiring a plurality of data pairs using one or more antenna coils, each data pair comprising an induced signal at a receiver and a corresponding toolface angle using a tool including at least one antenna assembly, to generate a measurement including obtaining information about the directionality of the formation by calculating areas of an induced signal function approximated by the plurality of data pairs.
