Summary

DTSC received USGS comments on the work plan and addendum for hydraulic testing in bedrock wells at the Topock Compressor Station, Needles, California. USGS suggested using a combined well-bore flow and depth-dependent sample collection tool to collect data through the packer in PGE-8. DTSC responded by requiring a smaller video camera to establish the condition of the well below 360 feet, and potentially conducting flow logging and depth sampling after the video is completed. PG&E responded that the well's construction would make flow logging results inconclusive and recommended against incorporating flow logging into the scope of work. USGS also commented on the need to test the permeability of potential fault zones with site-specific numerical models if production exceeds 5 gpm.
