North Aleutian
Shelf COST No. 1 Well - BIOSTRATIGRAPHICS Inc. Paleo Report |
The North
Aleutian COST No.1 Well was spudded September 8, 1982 and was completed
on January 14, 1983. The well operator was ARCO, Inc. Water depth at the
well site was 277 feet, and KB height above sea level was 85 feet. Well
sediment samples were recovered from 1380 to 17,150 feet, MD (TMD =
17,155 feet). It remains the only well drilled in the North Aleutian
Basin OCS area to the present time (May, 2008). The biostratigraphic
report for the well was prepared by Biostratigraphics Consulting
Micropaleontology of San Diego, California, and the summary results were
submitted to the operator on January 24, 1983. The report includes a
summary section and separate sections on foraminifera, palynology,
siliceous microfossils (SN - siliceous nannofossils - on charts),
calcareous nannofossils, and radiolaria. The foraminifera, palynology
and siliceous microfossil sections include check sheet listings of
species occurrences and abundances in the well.
The text files of the biostratigraphic report for the North Aleutian
COST No.1 Well have all been scanned and are presented here in .pdf
format. The report’s check sheets of microfossil occurrences have also
been scanned, and are presented here in two different formats: .pdf and
.tif files.
All the .pdf files are readable in Adobe Acrobat. The .tif files can be
opened with the Microsoft Office Document Imaging program, but some of
the larger files may not open on machines with less than 1 Megabyte RAM.
Adobe Acrobat will open the .tif files, but may take a few moments. The
.pdf files will open quickly and should be sufficiently sharp to make
check sheet details clear even at moderately high magnification.
Two brief reports on megafossils found in conventional core samples from
the well are also included here in .pdf format. The first, by Jay Marks,
reports on molluscan fossil materials; the other, by Dave Dilcher,
describes occurrences of leaf impressions and plant fragments.
