Tracking Injected Fluids: A Seismic Contrast Agent Breakthrough

A new class of acoustically active contrast agents holds promise for monitoring, mapping, and tracking fluids injected into the subsurface

February 2019

Researchers at PNNL are developing a new class of acoustically active nanomaterials designed to improve the high-resolution tracking of exploratory fluids injected into the subsurface. Once deployed in the field as stable injectable liquid, the new acoustic metamaterials could disrupt current technologies and improve the way subsurface geophysical monitoring and mapping is done.
