ECHO-DECAY-ACCELERATION DATA ACQUISITION METHOD FOR GAS IDENTIFICATION USING A LOW-FIELD GRADIENT |
| 摘要 |
<p>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.</p> |
