APPENDIX III GEOCHEMICAL EVALUATION LOGS

INTRODUCTION

Geochemical analyses were performed on the Norwegian Gulf well35/8-3, located in the northern North Sea, offshore Norway.Geochemical analyses were performed on the interval 900 - 3944m

Analyses were performed on both the original hole and thesidetrack section; the respective depth intervals are as follows:

Original hole : 900 - 3557mSidetrack : 3390 - 3944m

ANALYTICAL PROGRAMME

Cuttings samples for geochemical analysis were collected at fiftymetre intervals to a depth of 2150m. Thereafter the interval wasreduced to thirty metres, down to 3300m. From 3300m to totaldepth, cuttings samples were analysed at ten metre intervals. Aset of sidewall cores from the Cretaceous - Jurassic section andconventional cores were also analysed.

Following sample washing & preparation, the samples weresubmitted for Total Organic Carbon (TOC) determinations. This wasfollowed by Rock Eval pyrolysis analysis where TOC valuesexceeded 0.5%. In total 194 TOC and 175 pyrolysis analyses werecarried out. After inspection of these data, selected sampleswere submitted for visual kerogen analysis (including TAI) andvitrinite reflectance determinations. The vitrinite reflectancemeasurements were made on kerogen isolates.

Due to lack of sample material TOC determinationswere performed at 3818.5 - 3862.0m, and pyrolysisat 3930 - 3942.0m

Sidewall core data

Please note that some of the samples received were extremelysmall. Hence, in some cases it was not possible to perform bothpyrolysis and TOC determinations.
