Alaska Petroleum Reserve Well Logs and Core Analyses from 1946 to 1981

Well logs and associated geophysical data from the National Petroleum Reserve in Alaska, covering exploration activities from 1946 to 1981. The U.S. Geological Survey (USGS) compiled this data, which includes logs from the South Barrow No. 5 Well drilled in 1955 onward. Data formats include Schlumberger LISLOG, DRESSER, and DATOUT well logs.

Use Cases

• Correlate seismic velocity surveys with well log data to improve subsurface geological models.
• Analyze well core measurements like porosity and permeability to assess reservoir rock quality.
• Use digitized well logs and synthetic seismograms for stratigraphic interpretation and seismic calibration.
• Study palynology and micropaleontology reports to date rock formations and understand depositional environments.
• Model fluid saturation measurements from core analyses to estimate hydrocarbon reserves.

Strengths

• Data spans a 35-year period from 1946 to 1981, capturing early exploration history.
• Includes multiple complementary data types: well logs, core analyses, seismic surveys, and paleontology reports.

Limitations

• Data is temporally stale, with the last update recorded in 1981.
• Specific row counts, column details, and sample sizes for each dataset component are unknown.
• Geographic scope is limited to the National Petroleum Reserve-Alaska, which may limit broader applicability.
