INTRODUCTION Geochemical Screening using the Oil Shows Analyser was performed on 1425 cuttings samples, 39 core samples and 17 sidewall core samples. The interval covered was 724 to 5196m. The material was received as wet washed cuttings or core chips and analysed as an air dried ground powder. Analyses of three metre composite samples from 724 to 252 m was followed by the analysis of picked argillaceous material from 2523 to 5196 m. The core samples were generally taken between one and three metre intervals. Sands and sandstone were analysed to determine free hydrocarbon content.

SAMPLE PREPARATION Small samples of ditch cuttings are taken and thoroughly washed in cold water through a 2.36mm sieve and collected in a 18 micron sieve to remove cavings. Any large quantities of contaminants such as lost circulation material are removed at this stage. The washed material is then examined under a binocular microscope and any further contaminants removed. The samples are then air dried at room temperature to prevent the loss of 'free hydrocarbons' and then ground to a homogenous powder in preparation for pyrolysis. SAMPLE CONTAMINATION The effects of contamination, if unrecognized, can lead to misleading geochemical data. The major contaminants at the wellsite include paint chips, lost circulation material (mica, nuthulls, etc), steel fragments, and pipe dope. In the 7226/11-1 well contaminants were removed by picking at the wellsite from the pre-dried sample. Organic mud additives, especially those used for water loss control, can also cause serious contamination problems.
Another source of contamination to be aware of is caused by migrated hydrocarbons. The presence of migrated oil or bitumen in rock can give a major response in the vicinity of 3 degrees centigrade on the pyrogram (S1 ) while solid bitumen and the 'heavy end 1 fraction of petroleum has been found to produce a measurable response in the region 3-55 degrees centigrade. This is the same temperature range in which kerogen is cracked releasing hydrocarbons during pyrolysis. Thus large quantities of bitumen or migrated petroleum in rocks can affect the size and maximum temperature (Tmax) of the (S2) peak and cause non-source rocks to be falsely identified as source rocks as reported by Clementz (1979)*. The problems encountered as a result of hydrocarbon contamination may be overcome by solvent extraction using a 5:5 solution of tricloroethane and acetone. As a guideline, samples with high S1 values (greater than 1. mghc/g rock) are solvent extracted and reanalysed to obtain more valid values for S2 and Tmax. The S1 value obtained in the first analysis remains a useful indicator of oil accumulations, and degree of contamination. No samples were solvent extracted for 7226/11-1. * Clementz, D. 1979, 'Effect of Oil and Bitumen Saturation on Source Rock Pyrolusis 1, A.A.P.G. Bull., Vol 62 (12).
DESCRIPTION OF ANALYTICAL EQUIPMENT Principle of Operation Small quantities of sample (approx. 1 mg) are analysed by programmed pyrolysis in an inert Helium atmosphere. Any evoled hydrocarbons are detected by a Flame Ionisation Detector. The output from this sensor provides the peak data from the SO, S1 and S2 indices. In addition, the temperature, Tmax, for maximum generation of cracked hydrocarbons is measured by a probe monitoring oven temperature. On completion of the pyrolysis cycle the sample is transferred to a second oven. The sample is heated in air and any carbonaceous material remaining is converted to carbon dioxide, this is detected by a thermal conductivity detector (TCD), the output of which is the S4 peak. The Oil Shows Analyser thus derives the Total Organic Carbon content from the sum of the pyrolysed carbon (S+S1+S2) and the residual carbon (S4). The O.S.A. used the following analytical cycle. overleaf):- Pyrolysis: Carrier gas Helium Initial Isotherm 9 deg. C Isothermal Hold 2 minutes Second Isotherm 3 deg. C Isothermal Hold 2 minutes Temperature Ramp 3 deg/min Final Temperature 6 deg. C (Also see Fig. A
Oxidation: Oxidation Gas Oven Temperature Oxidation Time Air (after removal of C2) 6 deg. C 5 minutes The equipment was calibrated using a standard supplied by Exploration Logging Overseas, Inc. A quality control sample was run routinely every ten unknown samples, or every 24 hours if less than ten samples were analysed during this period. PRESENTATION OF RESULTS The processed data is expressed in terms of: 5 : Low temperature gas yield (mghc/g rock) 51 : Low temperature oil yield (mghc/g rock) 52 : High temperature hydrocarbon yield (mghc/g rock) Tmax : Temperatures at which maximum emission of hydrocarbons occurs. T.O.C. : Total Organic Carbon (weight percent of whole rock) comprised of S4 (residual organic carbon), plus 82% of the quantity S+S1+S2 T.P.I. : Total Production Index (S+S1/S+S1+S2) H.I. : Hydrogen Index (S2/TOC),

APPENDIX F 1 % RERUN SAMPLES
The following reruns were analysed in Exlog's Windsor Laboratory using a Rock Eval II and Leco Furnace. It has been noticed that there are marked discrepancies between the original wellsite pyrolysis values and these reruns where the samples are very lean. Having considered the data we conclude that there was a linearity problem with the O.S.A. used offshore. Consequently SI and S2 values of lean samples run offshore are lower than they should be. However, since the standard checks run on the O.S.A. are within accepted limits we feel that any data produced offshore which is reasonably rich will have credible results.
