Abstract: One or more first formation measurements sensitive to around a sensor string of a drill string deployed in a subsurface formation is received, A 1-D inversion of the first formation measurements is performed at a first reference point. One or more second formation measurements sensitive to ahead of a drill bit of the drill string deployed in the subsurface formation is received. A 1-D inversion of the second formation measurements is performed at a second reference point ahead of the drill bit of the sensor string to determine formation properties ahead of the drill bit, wherein the 1-D inversion of the second formation measurements is based on inversion results associated with the 1-D inversion of the first formation measurements.

Abstract: Methods to accurately plan and optimize clamped source excitation in ranging or telemetry operations approximate a well having a complex pipe structure as a simple solid pipe (“effective model”) with an effective pipe cross-section and resistance. The simple solid pipe is then treated as a thin wire and analyzed using a FAST Code.

Abstract: In accordance with presently disclosed embodiments, a system and method for determining a measurement for a pseudo receiver antenna with a different lateral position and a different azimuthal direction than at least two receiver antennas disposed on one or more wellbore tools is provided. The method involves transmitting an electromagnetic signal into a subterranean formation surrounding a borehole, and measuring one or more responses of the subterranean formation to the electromagnetic signal using at least two receiver antennas. The two receiver antennas are oriented in differing azimuthal directions relative to one or more tools to which the receiver are coupled, and arranged in a non-parallel angular orientation with respect to each other. The method then includes determining a response measured by a pseudo receiver antenna with a desired angular orientation and a desired azimuthal direction with respect to the one or more tools.
