NUCLEAR MAGNETIC RESONANCE LOGGING: EXAMPLE APPLICATIONS OF AN EMERGING TOOL FOR ENVIRONMENTAL INVESTIGATIONS
Spurlin, M.S., B.W. Barker, B.D. Cross, and C.E. Divine.
Remediation 29(2):63-73(2019)
Several nuclear magnetic resonance (NMR) field investigations were conducted to demonstrate the technology's viability as a site characterization tool for near-surface investigations. Use of NMR to detect vadose zone water provided hydrostratigraphic details that were used to evaluate drainable pore water versus pore water bound by capillary forces or electrochemically clay-bound water. While NMR produced hydraulic conductivity estimates like those from conventional hydraulic tests, it improved vertical resolution to provide additional information regarding the vertical heterogeneity of the formation along the entire length of the well or borehole. Bench-scale tests are presented that confirm NMR capability to reliably detect and quantify LNAPL saturation in situ. https://onlinelibrary.wiley.com/doi/epdf/10.1002/rem.21590
