Echo-decay-acceleration data acquisition method for gas identification using a low-field gradient |
摘要 |
A first NMR echo train is acquired with a single TE. A second NMR echo train is acquired with a first portion having the same TE and the second portion having a longer TE. When measurements are made with a low magnetic field gradient, processing the two echo trains can be used to determine gas in the formation. |
