Resource Potential Classification Evaluation of E₂S₄² Shale Oil in Damintun Depression

Abstract:

Shale oil resource potential classification evaluation is needed to precisely calculate the resource potential and prepare for the prediction of shale oil sweet spots. Geochemical analysis results shows that the E₂S₄² shale in Damintun Depression has strong hydrocarbon generation capacity. The classification evaluation criteria of E₂S₄² Shale oil in Damintun Depression was established according to the triple-division characteristic of measured TOC vs. S₁. The shale oil oiliness parameter S₁ was obtained by using improved logR method. The loss of hydrocarbon was recovered by chemical kinetics method. Volumetric method was used to calculate different grades of E₂S₄² shale oil in Damintun Depression. Grade I resource is 334 million tons. Grade II resource is 33 million tons. Grade III resource is 15 million tons. Grade I resource accounts for over 90% of the total resource content. High value area mainly concentrated near Well Shen223 and Well Shen224. Results shows that the E₂S₄² shale in Damintun Depression has good resource potential.
