Abstract:
1. A method for directing borehole drilling in a target earth formation, comprising the steps of: providing drilling equipment having a bottom hole assembly that includes a controllable directional drilling subsystem, and a logging-while-drilling directional measurement tool with a look-around and look-ahead capability, wherein the look-around capability comprises registering a direction from which maximum conductivity can be measured; determining the presence of a predetermined type of formation characteristic in the target formation; and navigating a drill path in the target formation with said drilling equipment, including receiving measurement signals from said directional measurement tool, obtaining, from the received measurement signals, indications of formation parameters with respect to said formation characteristic in the target formation, and controlling said directional drilling subsystem to drill in a direction determined as a function of said obtained indication of formation parameters.
