Abstract

Un aparato para llevar a cabo un experimento de resonancia magnética nuclear (RMN) en un pozo que penetra la tierra incluye: un transportador configurado para trasladarse a través del pozo; un ensamblaje de antena dispuesto en el portador y configurado para recibir una señal de RMN; y un circuito de ganancia activa que tiene una entrada acoplada a la antena y configurada para aplicar ganancia a la señal de RMN recibida y para proporcionar una señal de salida que comprende los datos del experimento de RMN. El aparato también incluye un circuito de retroalimentación configurado para alimentar la señal de salida de regreso a la entrada del circuito de ganancia activa; donde la señal retroalimentada a la entrada del circuito de ganancia activa se encuentra fuera de fase con la señal de RMN recibida y el circuito de retroalimentación proporciona un valor del factor de calidad eléctrica Q de un ensamblaje de antena que es menor que el valor del factor de calidad eléctrica Q del ensamblaje de antena sin el circuito de retroalimentación.
