DOE-Sponsored Project Pushes the Limits of Seismic-While-Drilling Technology

Green Car Congress

The harsh high-pressure, high-temperature environments found in deep onshore and offshore deepwater wells require special imaging technologies and were the reason for the development of the SeismicPULSER system. No drill bit seismic-while-drilling system available today has the full capabilities of the new system, according to the DOE.
