National Petroleum Reserve-Alaska Well Log Data for 1946 to 1981; USGS

The National Petroleum Reserve in Alaska (NPRA) is located in the primitive wilderness of Alaska's North Slope. The U.S. Geological Survey (USGS) began some geological surveying in this area in the early 1900's, and the U.S. Navy began geological and geophysical surveys and drilling in 1945 to appraise the petroleum potential of the Reserve. Information on surveys prior to 1955 may be obtained from the Branch of Alaskan Geology, Alaska Technical Data Unit, Mail Stop 48, U.S. Geological Survey, 345 Middlefield Road, Menlo Park, CA 94025. WELL LOG DATA Well logs and associated information are available from USGS. These data deal primarily with NPRA exploration and development since the drilling of the South Barrow No. 5 Well in 1955. Well log formats include Schlumberger LISLOG, DRESSER, and DATOUT. Included with some well log data sets are auxiliary information such as drilling history of the wells and velocity check-shot surveys. Well core analyses include porosity, permeability and fluid saturation measurements. MAJOR DATA SETS: Well logs; Digitized well logs; Well core analyses; Seismic velocity surveys; Synthetic seismograms; Palynology/Micropaleontology reports.
