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.

加州萨克拉门托谷（Sacramento Valley）的声波速度与密度测井资料已通过手工方式完成数字化。该类测井资料的扫描文件（PDF与TIFF格式）可从加州石油、天然气与地热资源管理局（California Division of Oil, Gas, and Geothermal Resources）官网获取，数据集包含该区域油气井井下实测的声波时差（transit times）与体积密度（bulk density）数据。此外，研究团队还从多类数据源汇编了声波速度与密度相关数据。加州石油、天然气与地热资源管理局官网亦提供了包含这些油气井基础信息的汇总表格。
