3.3 FMT Summary

Two runs with the Schlumberger MDT tool was run. In the first run -1A - nosamples was taken due to a short in the pumpmodule i.e. only pressure readingsobtained. Out of 45 attempts only 5 good pressure readings was obtained.Run IB was the run for sampling. Tree samples was taken and 4acceptable pressure points out of 26 attepts.

3.4 Well Testing

Well 6506/11-5S was considered as an observation well during the extended welltest of 6506/12-1 IS, to evaluate communication between the two wells. The cleanup of 6506/11-5S was performed by a separate standard well test string before thepressure monitoring completion string was attemted to be ran. As the evaluation ofthe pressure response in 6506/11-5S was the main objective the clean up flow periodwas limited to approx. 1 hour or one string volume only to ensure communication tothe formation and to clean out brine from the perforated interval.Unfortunally, due to technical problems, running of the pressure monitoringcompletion string was abondend and no pressure data observed during the test of6506/12-11S(R).

1 Introduction

Four gas samples from well 6506/12-1 (DST 2, DST 4B, DST 5D and DST 7) and one gassample from well 6506/11-5S (MDT) are analysed for gas and isotopic composition.

On the samples Q - Cs and CO2 are quantified. The 613C value is measured on methane,ethane, propane, the butanes and CO2. In addition the 5D value is measured on methane.

2 Analytical procedures

Aliquots of 1.0 ml of the gas samples are sampled with a syringe for analysis on a Porapak Qcolumn connected with flame ionisation (FID) and thermal conductivity (TCD) detectors. Thedetection limit for the hydrocarbon gas components is 0.01 |il/ml and 0.2 pi/ml for CO2-

For the isotope analysis 5 - 10 ml is sampled with a syringe and then separated into thedifferent gas components by a Carlo Erba 4200 gas chromatograph. The hydrocarbon gascomponents are oxidised in separate CuO-ovens in order to prevent cross contamination.The combustion products CO2 and H^O are frozen into collection vessels and separated.

The combustion water is reduced with zinc metal in sealed quarts tubes to prepare hydrogenfor isotopic analysis. The isotopic measurements are performed on a Finnigan MAT 251 anda Finnigan Delta mass spectrometer.

IFEs value on NBS 22 is -29.77 ± .06%o PDB,

The uncertainty in the 613C value is estimated to be ± 0.3%o PDB and includes all thedifferent analytical steps. The estimate is based on repeated analysis of a laboratory standardgas mixture. The uncertainty in the 5D value is likewise estimated to be ± 5%c.

3 Results

The volume composition of the gas samples is shown in Table 1 (normalised composition),and the stable isotope composition is shown in Table 2.

The molecular composition related to carbon isotope variations in methane from the gassamples from well 6506/12-1 and 6506/11-5S are plotted in Figure 1 (Schoell, 1983), thecarbon and hydrogen variations in methane are plotted in Figure 2 (Schoell, 1983) and thecarbon isotope variations in ethane related to the carbon isotope variations in methane inFigure 3 (Schoell, 1983).
