1. Introduction
Five canned cutting samples from the well 7131/4-1 were received from Statoil for gaschromatographic analysis of the Cl to C9 hydrocarbons contained in the headspace andoccluded gas.
This report contains the results of the analyses. The hydrocarbon concentrations areexpressed as \±l gas per kg of dried cuttings. The hydrocarbon composition is expressedin volume percent of all recorded hydrocarbons.
Aliquots of the headspace and occluded gas were sampled in vacuum tubes and sent toApplied Petroleum Technology AS, Norway (APT) for isotope analyses.
2. Experimental
2.1 Headspace gas
A septum was attached to the can and a sample of headspace gas was taken and injectedinto a gas chromatograph for analysis of Cl to C9 hydrocarbons.
The can was opened and the volume of the headspace was determined. The cuttingswere washed with water (ca. 30 °C) on 4.0, 1.0 and 0.125 mm sieves in order to removethe drilling mud, and were then weighed and dried.
2.2 Occluded gas
Prior to drying, an aliquot of the 1-4 mm fraction was crushed in water for 10 minutesusing a gas-tight ball mill. An aliquot of the evolved gas was injected into a gaschromatograph for analysis of Cl to C9 hydrocarbons.
2.3 Samples for isotope analysis
10 ml of each gas fraction (headspace and occluded gas) were extracted from allsamples and injected to vacuum-based test tubes provided by Applied PetroleumTechnology AS, Norway (APT). The tubes were sent to APT for analyses.
2.4 Gas chromatographic analysis
The gas was analysed on a gas chromatograph fitted with an gas injector. The GCtemperature program started at 35 °C, since separation of alkenes from alkanes was ofno interest in this project. The instrument was fitted with a capillary column connectedto an FID for hydrocarbon detection. Details of the instrumentation are listed in Table2.1.

2.6 Quantification
A 1000 ppm (fJ.1/1) standard gas sample containing methane, ethane, propane, i-butane,n-butane, n-pentane and n-hexane was used for quantification. The variation betweenall standard analysed over a period was small (Table 2.3), and the average responsefactors were used for quantification of all samples. The response factor for n-C5 wasused for all compounds eluting between n-C4 and n-C5 and so on. For the C6-C7, C7-C8 and C8-C9 component groups the response factors were extrapolated based onmolecular mass.
A 100 ppm (|ul/l) standard gas sample containing methane, ethane, propane, n-butane,n-pentane and n-hexane was used for control of linearity.
Rock-related concentrations (in ul/kg) for compounds having a concentration of lessthan 0.2 ppm (^il/l) in the analysed gas are not reported, as this corresponds to an area ofabout 0.08, which is the lowest reliable area in the gas chromatograms.

2.7 Concentrations and ratios
The yields of hydrocarbons (|il/kg dry rock) in headspace (H) and occluded (O) gas andthe sum of H + O are given in Table 4.3, and the hydrocarbon composition (volume %)is given in Table 4.4. Selected summary data and peak ratios are calculated and reportedin Table 4.5. Abbreviations used in Table 4.5 are explained in Table 2.4.
As coelution of 3-EC5 and 2,2,4-TMC5 with t-l,2-DMCyC5 and of c-l,2-DMCyC5with MCyC6 cannot be avoided at the chosen experimental conditions, only some ofthe Mango ratios can be calculated (see tables).

Coelution of compounds'CyC5' contains coeluting 2.3-DMC4.'t-1,2-DMCyC5' contains coeluting 3-EC5 and 2,2,4-TMC5. The Mango ratios P3 and N15 can therefore not be calculated.The Thompson ratios H and I may be slightly affected.'MCyC6' contains coeluting c-1,2-DMCyC5. The Mango ratios N15 and N16 can therefore not be calculated. TheThompson ratios C, F and H may be slightly affected.Toluene coelutes with 2,3,3-TMC5 and 'n-C8' contains an unknown coeluting compound. The Thompson ratios B, H and Xmay be slightly affected.

2.8 Water content
The water content of the cuttings was determined by weighing the fractions before andafter drying at 35 °C for at least 24 hours. The dry weight of the rock used for occludedgas analysis was determined using the wet weight of this rock and the water content ofthe remaining 1-4 mm fraction. Water contents for the three individual grain sizefractions are listed in Table 4.2.
3. Comments on samples and analytical data
The wet cutting samples were received in pressure-lid cans of 1 1 volume at ambienttemperature. Secondary modification of the gas composition by microbial activitycannot be completely ruled out.
Sample descriptions are listed in Table 4.1.
One of the samples, H6167 at 931 m depth, contained no fraction above 4 mm, and avery small fraction between 1 and 4 mm. The whole of this fraction was used in theoccluded gas analyses, and the water content was estimated and set to 30 %.
Some of the peak ratios show erratic values for the shallowest sample. This is typicallydue to low concentration or absence of the respective compounds. Care should,therefore, be taken in the interpretation of these ratios. Also note the remarks in Table2.4 on the possible effects of coelution on the various peak ratios.
