Geel C.e.а. Shale gas characteristics of Permian black shales in South Africa: results from recent drilling in the Ecca Group (Eastern Cape)

2013,№40, Р.256-265,FIG.8,Lit.25n. Publ.Elsevier Ltd. European Geosciences Union General Assembly 2013, EGUDetailed lithological, sedimentological, petrographic and geochemical analyses of the lower three formations of the
Ecca Group in the Greystone area, Eastern Cape, South Africa, close to the tectonic front of the Cape Fold Belt, are
described with a particular focus on the black shales of the Whitehill Formation. Fresh core samples from a 300m
deep borehole were analysed as follows: petrography, XRD and XRF, open system pyrolysis and thermovaporization,
TOC/Rock Eval, SEM microscopy, vitrinite reflectance, stable isotopes and porosity using mercury intrusion. This
ongoing investigation gives insight into the gas potential of the Karoo black shales.
