- Abstract:
- The U. S. Geological Survey (USGS) Central Energy
Resources Team's Organic Geochemistry Laboratory
(CERTOGL) is a research laboratory devoted to the
investigation of the origin and occurrence of fossil fuels.
One such study involved the petroleum potential of the
National Petroleum Reserve in Alaska (1988). In order to
archive geochemical results of this study, the USGS
developed an Alaskan Organic Geochemical Data Base
(AOGDB) in 1978 to house the data generated from USGS
laboratories and various sub-contracted laboratories. The
accumulated data resided in a flat text file entitled "PGS"
and was originally maintained by Petroleum Information
Corporation. The information herein is a breakout and
creation of tables from the master flat file form into a
relational data base format. No electronic data such as
chromatograms, etc. is available for this data file. Additional information about “PGS” and Alaska geochemistry data and
interpretation can be obtained in Geology and Exploration of the National Petroleum Reserve in Alaska, 1974-1982, USGS
Professional Paper 1399 (see the sections by Claypool and Magoon, p. 451-481, and Magoon and Claypool, p. 519-549.)
The data base management software originally used in the
creation of the AOGDB is MicroRim Corporation's RBase
for DOS™, a data base package designed for use on IBM
XT or AT or equivalent computers with MS-DOS or
equivalent disk operating systems. The AOGDB consists of
Rbase tables, which have subsequently been converted to
Microsoft Access 97™ tables and ASCII tables. Each table
consists of vertical columns and horizontal rows of
information where each row represents one sample and the
columns within each row represent specific information
about the sample. There is only one driving table:
HEADER_PGS which contains generic sample information
and permits a relational pathway to the data tables via the
primary key: WMO (derived from World Meteorological
Organization and the American Petroleum Institute see
below.)
- Purpose:
- This data was originally collected in an attempt to
better understand the geology and organic geochemistry
of the state of Alaska.
