Well Log Data

available from the National Geophysical Data Center
for the

Gulf of Mexico Outer Continental Shelf

Data Announcement 82-MGG-06 (revised 12/84)

The National Geophysical Data Center (NGDC) has available for purchase well log data and auxilliary reports originating from approximately 1,300 expired Federal Outer Continental Shelf oil and gas leases in the Gulf of Mexico. These data include core analyses and drilling reports in the offshore areas of Louisiana, Texas, and Florida. All wells were drilled by private industry inthe late 1940's to the 1970's. Subsequent well testing resulted in nearly 8,000 paper logs which are now available on 16-mm microfilm from NGDC. The Minerals Management Service (MMS) has provided these data to NGDC for public dissemination.

Data Available

NGDC operates a digital inventory of well-log data from the expired wells described above. The inventory is searchable by criteria such as latitude, longitude, API number, block, lease, well number, company, or log type. Various types of downhole logs exist for each well as outlined below. Other log types may also be available.
