Abstract
La adquisición de registros con NMR de las formaciones de hidrocarburo se puede realizar con una técnica de NMR de multifrecuencia de gradiente utilizando una densidad de empaquetamiento aumentada de los volúmenes sensibles de modo que interfieran los pulsos de radiofrecuencia (RF) para volúmenes sensibles adyacentes. Un método de ejemplo puede incluir aplicar la primera y segunda secuencia de pulsos de RF en la primera y segunda frecuencia, respectivamente, la segunda secuencia se aplica a un intervalo de tiempo luego de la primera secuencia; adquirir los datos de relajación de NMR del primer y segundo volumen sensible que corresponden a la primera y segunda frecuencia, respectivamente; y seleccionar la primera y segunda frecuencia y el intervalo de tiempo para permitir la interferencia entre la primera secuencia de pulsos de RF y los datos de relajación de NMR del segundo volumen sensible para aumentar una relación señal-ruido y una relación señal-ruido por raíz cuadrada de tiempo de los datos de relajación de NMR.
