Schlumberger GECO-PRAKLA GEOLAB^NOR GEOCHEMICAL REPORT
Schlumberger GECO-PRAKLA GEOLAB8BNOR Chapter 1 INTRODUCTION The geochemical study included investigation of potential source rocks, ranging from Tertiary claystones to Shetland Gp. claystones. Potential reservoir intervals were also analysed, with special emphasis
Schlumberger GECO-PRAKLA GEOLABJfiNOR 1.2 Analytical Program The analytical program for well NOGS 16/1-4 was based on the samples selected by Statoil for screening and detailed follow-up analysis. The number of samples for the individual analyses

Schlumberger GECO-PRAKLA GEOLABJIJNOR Removal of Asphaltenes The EOM is dissolved in tetrahydrofuran in a flask and n-pentane is added to precipitate the asphaltenes.the solution is then stored in the dark and at ambient temperature for at least 8 hours. The solution is then filtered (Baker 10-spe system) and the precipitated asphaltenes returned to the original flask by dissolution in dichloromethane.

Schlumberger GECO-PRAKLA GEOLABJfiNOR Aromatic Fractions Alkyl-substituted Benzenes The M/Z 106 fragment ion is often used to detect the alkyl-substituted benzenes. It is especially useful for the detection of di-substituted benzenes. M/Z 134 can also be used
Schlumberger GECO-PRAKLA GEOLAB!BNOR Aromatic Steranes Monoaromatic steranes are detected using the M/Z 253 fragment ion, while the triaromatic steranes are detected using the M/Z 231 fragment ion. 11
