Organic geochemistry, burial history and hydrocarbon generation modelling of the upper jurassic madbi formation, masila basin, Yemen

Cuttings samples of shales from the Upper Jurassic Madbi Formation from boreholes in the centre-west of the Masila Basin were analysed using organic geochemistry (Rock-Eval pyrolysis, extract analysis) and organic petrology. The shales generally contain more than 2.0 wt % TOC and have very good to e...
