Worldwide Well Logs with Values of Conductivity, Bulk Density, Porosity, Grain Density, Resistivity, and Sonic Ratio Collected by the Ocean Drilling Program (ODP)

World-wide digital well log data collected for the Ocean Drilling Program (ODP) by Schlumberger Offshore Services under contract to Texas A&M University. The data were in turn converted to ASCII form and released to NGDC for longterm archival by the Borehole Research Group (BRG) of the Lamont-Doherty Earth Observatory, Columbia University. Some of the data parameters contained in the data files relate to conductivity, bulk density, porosity, resistivity, grain density, and sonic ratio. Other parameters are present and may vary for each well log. The data were originally available on magnetic (field) tapes produced onboard the drill ship Joides Resolution in a customer-supported format called the Log Information Standard (LIS). The BRG at Lamont translated the data into a publicly-readable ASCII format. These data are available and searchable online from the BRG.
