초록 ▼

A technique utilizes the acquisition of data from desired subterranean regions via a logging system. The logging system is constructed for use in a wellbore and comprises a transmitter module having a transmitter antenna. Additionally, the logging system utilizes a receiver module spaced from the transmitter module and having a receiver antenna. The transmitter antenna and the receiver antenna are oriented to enable sensitivity in desired directions, such as ahead of the logging system.

1. A method to determine the presence and position of one or more resistivity contrasts in a formation ahead of a well drilling system, comprising: making resistivity measurements using a downhole tool to obtain a measured response;computing an expected response of the downhole tool based on a particular formation model;comparing the measured response to the expected response to determine the presence andposition of the one or more resistivity contrasts ahead of the well drilling system;outputting the determined presence and position of the one or more resistivity contrasts, andusing the presence and position of the one or more resistivity contrasts for geosteering, landing a wellbore, pore pressure detection, and positioning for core sampling. 2. The method as recited in claim 1, further comprising determining a distance between a reference point and one or more bed boundaries. 3. The method as recited in claim 1, further comprising determining the presence and position of one or more resistivity contrasts in a formation around the well drilling system. 4. The method as recited in claim 1, wherein the downhole tool includes a drill bit or has one or more antennas located in close proximity to the drill bit. 5. The method as recited in claim 1, wherein the downhole tool has one or more directional antennas. 6. The method as recited in claim 1, wherein comparing includes computing a difference between the measured response and the expected response. 7. The method as recited in claim 1, wherein the measured response is a component of an electromagnetic coupling tensor or a combination of components of the electromagnetic coupling tensor. 8. The method as recited in claim 1, wherein the expected response is a component of an electromagnetic coupling tensor or a combination of components of the electromagnetic coupling tensor. 9. The method as recited in claim 1, wherein outputting includes displaying on a screen and/or plotting on a tangible medium.
