Digitized sonic velocity and density log data of Sacramento Valley, California

Sonic velocity and density well logs in the Sacramento Valley in California were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website and the data consist of transit times and bulk density measured downhole in oil and gas wells in the region. Sonic velocity and density data were also compiled from a number of sources. A summary table also provides basic information of these wells, available on the California Division of Oil, Gas, and Geothermal Resources website.
