INTRODUCTION
This Open File contains digital files of C15+ saturate fraction gas chromatograms of source rock extracts obtained from wells drilled in the Jeanne d'Arc Basin. Tables with selected Rock-Eval and gross composition data are also provided. Samples from wells drilled in the last two years are not included because of confidentiality reasons. This Open File partly follows an earlier one which included digital files of gasoline range and saturate fraction gas chromatograms of crude oils from this area. With the present report we are able to make use of recent technological advances to provide the data in an electronic format that should make it more amenable for use. GC-MS data will be released in a similar format at a future date. The data in this report can also be accessed from the BASIN data base operated by GSC Atlantic.
The C15+ saturate fraction gas chromatograms have been obtained over the last ten years or so. More than one temperature program has been used for gas chromatography (see below) and consequently there is some variation in retention times of compounds between different samples.
The significance of the data will not be discussed here. This will be done in some future publications. However, it should be pointed out that gas chromatograms from some wells, including Lancaster F-70, South Brook N-30, South Merasheen K-55 and Whiterose A-90 are affected by contaminations introduced during drilling.
