Cooper basin Toolachee and Patchawarra sands are difficult to map due to strong seismic reflections from Permian coals. Seismic amplitudes are mainly driven by coal thickness instead of lithology (sand vs shale). We proposed a method for obtaining better sand prediction. This method uses AVO ...
The Faku-Kaiyuan study area is located in northern Liaoning, geotectonically in the eastern section of the northern margin of the NCC, the southern margin of the Songliao Basin, and south of the Solonker-Xar Moron-Changchun- Yanji suture zone, with the Faku study area to the west of the ...
with each other, except for RT and RHOB values. This inconsistency more likely happened due to the regional difference and bad quality of the data obtained from the publicly shared domain, RRC. The parameters RT and RHOB are negatively or weakly correlated, as shown in the heatmap, which ...
with the large-scale transgression process, the deep-water basin facies siliceous rocks and siliceous shale were deposited in the Kaijiang-Liangping Trough in northern Sichuan, which is called the Dalong Formation. The organic-rich shale deposited in the Late Permian has become an important coalbed...
