Prediction and evaluation of the Sinian-Lower palaeozoic oil-gas prospective areas in the basin-mountain transitional region on the western side of the Xuefeng Mountain

Based on the above-mentioned work and the available information, this paper proposes four oil-gas favorable zones(Lichuan-Enshi, Shimen-Sangzhi, Renhuai-Jinsha and Wulong-Daozhen) and two relatively promising gas districts(Meitan-Sinan and Huangping-Majiang). The achievements obtained by the authors have laid important foundation for further petroleum geological survey and target block evaluation on the western side of the Xuefeng Mountain.
