Research on the Oil-Bearing Difference of Bedding Fractures: A Case Study of Lucaogou Formation in Jimsar Sag [PDF]

Geofluids, 2021
Lucaogou formation in Jimsar sag is host to large quantities of bedding fractures which are known to play a critical role in the enrichment, accumulation, and efficient development of tight oil. In this paper, we examine and finely characterize the development of the bedding fractures found in the upper and lower sweet spots of Lucaogou formation of ...

Research on the Pore Evolution of Oil Shale under Different Thermal Treatment Temperatures Using NMR and FE‐SEM Methods

Geofluids, Volume 2023, Issue 1, 2023., 2023
Underground in situ pyrolysis for oil shale extraction is currently significant; the evolutions in microstructure, porosity, and permeability parameters are essential factors in evaluating the productivity of oil shale after pyrolysis. With the underground oil shale reservoir core, obtained from Jimsar Sag in the Junggar Basin in China, as the research

Effects of parent well spacing on the poroelastic behaviors in the infill zone in shale oil reservoirs: A case study in Jimsar Shale Oil, China

Energy Science &Engineering, Volume 10, Issue 4, Page 1043-1054, April 2022., 2022
The effect of parent well spacing on the poroelastic changes in the infill zone is not monotonic. Tight spacings lead to decreased breakdown pressure and decreased production potential. Loose spacings result in slightly increased breakdown pressure, while the production potential is preserved.

Extremely High Primary Productivity and Organic Matter Enrichment in Lacustrine Sediments: Late Triassic Chang 73 Sub‐Member, Western Ordos Basin

Geofluids, Volume 2022, Issue 1, 2022., 2022
The 7th member of the Late Triassic Yanchang Formation is the most important Mesozoic source rocks and shale oil reservoir in the Ordos Basin. The hydrocarbon potential and organic matter enrichment mechanism of this organic‐rich member are questioned because of the high heterogeneity of continental sediments. In particular, the lack of drilling in the
