Abstract
In addition, the oil generation capacity of Lucaogou Formation, with abundant oil-prone organic matter (Type I/II1 kerogen with HI values ranging from 421.18-918.41 mg HC/g TOC) in the early mature to mature stage (Tmax values ranging from 435 to 451 °C), is considerable. The Rock-Eval oil saturation index (OSIS1/TOC Ã 100) values range from 6.04-164.07 mg HC/g TOC, suggesting the Lucaogou Formation contains producible oil. The high brittle mineral (including quartz and carbonates) contents (> 50% wt%) and traces of clay minerals (< 5 wt%) imply that the Lucaogou Formation is likely to respond well to hydraulic stimulation. Consequently, the Lucaogou Formation in Santanghu Basin is expected to be a potential lacustrine shale oil play.
