Optimization of shale gas reservoir evaluation and assessment of shale gas resources in the Oriente Basin in Ecuador

Abstract The petroleum geological features of hydrocarbon source rocks in the Oriente Basin in Ecuador are studied in detail to determine the potential of shale gas resources in the basin. The favorable shale gas layer in the vertical direction is optimized by combining logging identification and co...
