James Rutledge is a Geophysicist-Seismologist at Los Alamos National Laboratory.  His research interests include: geologic CO₂ storage; induced seismicity; sensor systems and borehole seismology.  As a Staff Member and contractor at Los Alamos National Lab, James has worked as principal investigator on several studies including: 1) reservoir fracture mapping and characterization in oil, gas and geothermal fields using induced microearthquakes associated with hydraulic fractures, waterflood and CO₂ injection, primary production, and reservoir compaction; 2) in situ measurements and modeling of seismic wave attenuation and scattering in various rocks types using vertical seismic profile data; and 3) cross-borehole seismic imaging.

During Phase II of the SWP, James was the site coordinator for the Aneth Enhanced-Oil-Recovery and CO₂ Sequestration Project.  He was the technical lead on the microseismic monitoring at Aneth and contributed to time-lapse VSP studies at both Aneth and SACROC.
