Data from nuclear magnetic resonance (NMR) well logs

Summary

The goal of this project is to take pore-scale information from nuclear magnetic resonance (NMR) well logs and relate this to larger scale seismo-acoustic measurements through the theory of poroelasticity.

 

In the first year of this project, Southwest Research Institute (SwRI) investigated the seismic response of fine-scale layering from stochastic and deterministic viewpoints; analyzed seismic, acoustic, and well log data from the Siberia Ridge gas field in Wyoming; and obtained acoustic, NMR, and x-ray tomography data from a carbonate aquifer in Florida.

 

This work is sponsored by the U.S. Department of Energy.
