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

Occurrence, Genesis, and Significance of Analcime in Fine‐Grained Sedimentary Rocks

Geofluids, Volume 2022, Issue 1, 2022., 2022
Natural analcime, an aluminosilicate mineral with multiple genetic mechanisms, widely occurs in fine‐grained sedimentary reservoirs rich in oil and gas. Researchers have discussed the source and formation mechanism of reservoirs and the influence of morphology formation, occurrence characteristics associated with minerals, geochemical data, and Si/Al ...

The Impact of Lamina Characteristics and Types on Organic Matter Enrichment of Chang 73 Submember in Ordos Basin, NW China

Geofluids, Volume 2022, Issue 1, 2022., 2022
The Chang 7 member in Ordos Basin is an important shale oil exploration layer, with new shale‐oil discoveries in recent years. The Chang 73 submember is rich in organic shale, which is the main source rock of shale oil in the Yanchang Formation. In order to clarify the lamina structure, composition, types, and distribution characteristics in Chang 73 ...

An Improved Model for Evaluating the Brittleness of Shale Oil Reservoirs Based on Dynamic Elastic Properties: A Case Study of Lucaogou Formation, Jimusar Sag

Geofluids, Volume 2022, Issue 1, 2022., 2022
Rock brittleness is a critical factor affecting the stimulation of shale oil reservoirs. For efficient development of the shale oil in Lucaogou Formation, Jimusar Sag, the brittleness of the sweet spots needs to be evaluated. In this paper, the triaxial compression, acoustic wave measurements, and three‐point bending tests were carried out on the ...

Controlling Effect of Wave‐Dominated Delta Sedimentary Facies on Unconventional Reservoirs: A Case Study of Pinghu Tectonic Belt in Xihu Sag, East China Sea Basin

Geofluids, Volume 2022, Issue 1, 2022., 2022
In order to find the “sweet spots” of unconventional oil and gas from the Pinghu Formation in the Pinghu Tectonic Belt, we are committed to clarifying the development and distribution rules of coal‐measure source rocks and tight reservoirs as well as the controlling factors. Using 3D seismic and logging data, combined with logging constraints of target
