Intact microbial fossils in the Permian Lucaogou Formation oil shale, Junggar Basin, NW China
International Journal of Coal Geology, 2015Abstract The Permian Lucaogou Formation was deposited in a deep stratified lake with good preservation of the organic matter in the sediments likely due to anoxic bottom waters. The Lucaogou Formation oil shale contains excellent source rocks with high TOC contents (12.4–32.9 wt.%) and high HI values (547–869 mg HC/g TOC). The maceral compositions of

Hydrogen and oxygen isotopes provide new evidence for estimating the composition of hydraulic fracturing flowback fluid. However, water-rock interaction between the fracturing fluid and the reservoir rock could have a negative effect. Thus, a comprehensive investigation of hydrogen and oxygen isotope exchange during water-rock interaction can greatly ...

ABSTRACT This study proposes a new method for estimating tight oil resources in a closed petroleum system using an alternative mass balance model. The proposed approach primarily derives resource estimates based on a large volume of Rock-Eval pyrolysis data.

ABSTRACT The Middle Permian Lucaogou Formation in the Junggar Basin hosts a suite of organic‐rich fine‐grained sedimentary succession of continental lacustrine facies, whose deposition was prominently governed by volcanic‐hydrothermal activities. Most prior investigations have predominantly focused on deciphering the dominant controls
