National Geophysical Data Center


Outer Continental Shelf - Offshore California

Data Announcement 85-MGG-05

Well logs and auxiliary information for 4 privately drilled test wells are now available for purchase from the National Geophysical Data Center (NGDC). These data were generated by private companies that drilled exploratory oil and gas wells in areas for which the proprietary terms of the leases have terminated. These wells are in addition to 78 previously advertised wells released to NGDC by the Minerals Management Service, U.S. Department of Interior, for public dissemination. A summary of the types of well logs and auxiliary information now available for these wells is given below.

Data Available

Data for the 4 wells are available on 1 roll (No. 2144) of 16-mm microfilm
