Patent number: 10677956Abstract: A method for measuring one or more properties of a formation includes applying a magnetic field to a subterranean formation using a downhole tool. A radiofrequency signal is transmitted into the subterranean formation that is exposed to the magnetic field. The radiofrequency signal induces a transverse magnetization in the subterranean formation, and the transverse magnetization induces an initial voltage signal in the downhole tool. The initial voltage signal is amplified using a first amplifier in the downhole tool such that the first amplifier outputs a first amplified voltage signal. The first amplified voltage signal is introduced to an input of the first amplifier, such that the first amplifier amplifies the first amplified voltage signal and outputs a second amplified voltage signal.Type: GrantFiled: September 8, 2016Date of Patent: June 9, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Krishnamurthy Ganesan, Soumyajit Mandal, Van D.
