Diagenetic Heterogeneity of Deep Sandstones and Its Relationship to Oil Emplacement: A Case Study from the Middle Jurassic Toutunhe Formation in the Fukang Sag, Central Junggar Basin (NW China)

<div>Wireline logs of the Toutunhe Formation in the studied wells showing sample depths. Only the point-counted samples are included. Depositional facies associations and lithofacies are interpreted based on core description. Calcite tightly cemented intervals are shown. GR/API: natural gamma-ray log; RT/Ω·m: formation true resistivity.</div>
