Fremgangsmåte for å bestemme tilstedeværelse av og posisjonen til én eller flere resistivitetskontraster i en formasjon foran et brønnboringssystem

摘要

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.
