Organic Geochemistry

 
Fact sheet, Organic Geochemistry. The Department of Geochemistry of the Geological Survey of Denmark and Greenland (GEUS) comprises a fully equipped laboratory dedicated to organic geochemistry and petrography. Over more than fifteen years, extensive experience within organic geochemical analysis of source rocks, oils, coals and recent sediments has been gained, and a large data- and sample-base has been collected.


Organic Geochemical analysis The Department of Reservoir Geology of the Geological Survey of Denmark and Greenland (GEUS) comprises a fully equipped laboratory dedicated to organic geochemistry and petrography.
Over more than 25 years, extensive experience within organic geochemical analysis of source rocks, oils, coals and recent sediments has been gained, and a large data- and sample-base has been collected.

A key staff of three scientists and three technicians ensures that expertise within all relevant fields is available.

The laboratory offers services within organic geochemical screening analysis as well as advanced analyses. Screening analyses available include Total Carbon (TC) Total Organic Carbon (TOC), Total Sulphur (TS), elemental analysis (C,H,N) and Rock-Eval-type pyrolysis using the Source Rock Analyzer instrument (Humble Instruments) that yields similar data as the Rock-Eval. Other bulk analysis techniques available include bulk kinetic studies (using the Source Rock Analyzer instrument). Further analyses include solvent extraction using a Soxtec® apparatus and group type fractionation by Medium Performance Liquid Chromatography (MPLC), Gas Chromatographic analysis (GC) of both saturated and aromatic compounds, and biological marker analysis by coupled Gas Chromatography - Mass Spectrometry (GC-MS and GC-MS-MS). Futhermore, for identification of unknown compounds, isolation of individual biological markers by means of High Performance Liquid Chromatography (HPLC) is routinely carried out.

The laboratory conducts pure research projects, offers its services on fully commercial terms, or participates in cooperative projects.

Research includes inter alia studies in the North Sea, Greenland, the Faeroe Islands, areas west of Shetland, the Baltic Countries, Serbia, Vietnam, Thailand, Nigeria, and Belize.
