6 Abstract This report is a data release of Rock Eval, total organic carbon and adsorption isotherms for selected samples of the Duvernay and Muskwa formations generated for the Energy Resources Conservation Board/Alberta Geological Survey project on shale gas resources in Alberta. A few samples were also taken in adjoining formations, such as the Majeau Lake, Beaverhill Lake, Ireton, Fort Simpson, Cooking Lake and Swan Hills. This data release complements other reports and data from the same project, as listed in Table 1. ERCB/AGS Open File Report 21-4 (May 21) vi

7 1 Introduction The Energy Resources Conservation Board/Alberta Geological Survey (ERCB/AGS) initiated a project in 27 to evaluate shale gas resources in Alberta, to determine the quantity and spatial extent of these resources. Alberta Geological Survey (AGS) is releasing a series of reports to disseminate data and knowledge from the project. The first formations chosen for evaluation were the Colorado Group (Beaton et al., 29a; Pawlowicz et al., 29b) and the Banff and Exshaw formations (Beaton et al., 29b; Pawlowicz et al., 29a). Readers can download these publications from the AGS website ( This report disseminates results from adsorption isotherms, Rock Eval and total organic carbon (TOC) analysis associated with the Duvernay and Muskwa formations. In addition to the analyses listed above, AGS ran a series of analyses on core samples (Table 1). The data generated from the project will be combined with additional data to map and estimate shale gas resources in the province. Table 1. Analyses performed on core samples and the organization that performed the analyses as part of the shale gas resource evaluation project.

10 3 Analytical Methods and Results A total of 182 core samples was selected for analysis. The analyses itemized in Table 1 were performed on selected samples, as indicated in Appendix 2. Schlumberger/TerraTek performed an adsorption isotherm analysis, along with Rock Eval 6 and total organic carbon (TOC) analyses on selected samples. The Geological Survey of Canada carried out Rock Eval 6 and TOC analyses on the majority of samples. References for the methodology are Bustin and Nassichuk (22) and Mavor and Nelson (1997) for isotherms, and Lafargue et al. (1996) for Rock Eval and TOC. Appendices 3 and 4 contain the data. Adsorption isotherms indicate the gas storage capacity of the organic matter within a sample. Rock Eval and TOC indicate the current amount of hydrocarbon in a sample and the potential for in situ kerogen to generate hydrocarbon. Total organic carbon indicates total organic matter (suggestive of hydrocarbon potential). This dataset is useful in determining hydrocarbon potential of a sample.
