1 Introduction

This report gives the result of routine vitrinite reflectance analyses of 26 samples fromwell 6204/10-2 and 6204/10-2R offshore Norway.

2 Material

The material was provided from the client as 9 cuttings samples, 15 side wall cores and 2core chips. Information on lithology in well 6204/10-2 and 6204/10-2R was providedfrom the client and is plotted in table 1.

3 Analytical techniques

3.1 Preparation

The cuttings samples and the side wall cores were treated with hydrochloric andhydrofluoric acid prior to further preparation. The aim was to avoid soft and expandingmineral phases in order to ensure good polishing quality. The sample material resultingfrom the acid treatment and the bulk core chips were embedded in an epoxy resin to makebriquettes, ground flat and polished using 0.25 micron diamond paste and magnesiumoxide as the two final steps.

3.2 Analysis

The analytical equipment being used was a Zeiss MPM 03 photometer microscopeequipped with an Epiplan-Neofluar 40/0.90 oil objective. The sensitive measuring spotwas kept constant for all measurements at about 2.5 micron in diameter. Themeasurements were made through a green band pass filter (546 nm) and in oil immersion(refractive index 1.515 at 18°C). The readings were made without a polarizer and using astationary stage. This procedure is called measurement of random reflectance (%Rm).The photometer is calibrated daily against a standard of known reflectance (%Rm=0.588) and routinely (daily) checked against two other standards of significant different

reflectances ( %Rm=0.879 and 1.696). A deviation from these values of less than ±0.01and ±0.02 respectively is considered as acceptable. The calibration is routinely checkedduring the course of measurements at least every hour, and a deviation of less than±0.005 is considered as acceptable.

For each sample at least 20 points were measured if possible, and quality ratings aregiven to various important aspects which may affect the measurements. These aspects areabundance of vitrinite, uncertainties in the identification of indigenous vitrinite, type ofvitrinite, particle size, particle surface quality and abundance of pyrite.
