英文摘要The Silurian (Llandovery) hot shales in southeastern Turkey have excellent source rock potential, with an average total organic carbon (TOC) of 5.9 wt. % and generation potential values of 14.9 mg HC/g TOC. The hot shales contain type II organic matter and demonstrate oil and secondary gas generation potential. Hydrogen indices range from 36 to 510 mg HC/g TOC, depending on maturity. The hot shales in the Gulf Kevan 1 and Turkish Petroleum (TP) Do¢gan 1 wells are immature-early mature with a vitrinite reflectance equivalent (Requ) of 0.58%-0.76%. The hot shales in the TP So¢guktepe 1 and TP K. Migo 2 wells are mature and in the oil window at 0.78%-0.92% Requ. The hot shales are interpreted to be in the wet gas-condensate maturity window with 1.08%-1.30% Requ in the TP G. Hazro 2 and TP-Arco Abdü laziz 1 wells. Corrected (evaporation loss restored using oil API gravity values) oil saturation index values (OSIc) within the Gulf Kevan 1, TP Dog¢an 1, and TP-Arco Abdü laziz 1 wells are less than 100mg HC/g TOC, which indicates that unconventional commercial oil production is not probable. The OSIc values of the mature hot shales at the TP So¢guktepe 1, TP K. Migo 2, and TP G. Hazro 2 wells all exceed 100 mg HC/g TOC, indicating potentially producible oil and wet gas condensate. Thus, producible oil and wet gas condensate in the hot shale play appear present in areas that have been assessed as having between 0.8% and 1.1% Requ. © 2020 The American Association of Petroleum Geologists.
