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

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.

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

Geofluids, Volume 2022, Issue 1, 2022., 2022 In order to maximize the production of unconventional oil and gas reservoirs, the well spacing has been shrinking continuously. Thus, the interwell fracturing interference usually occurs, which brings some problems affecting the fracturing efficiency.

Energy Reports, 2022 Long horizontal sections, small well spacings, and dense cutting are the main methods for shale reservoir development. However, there are still significant differences in oil production after large-scale fracturing of horizontal wells due to reservoir heterogeneity. This study presents a fracturing design method based on sweet spot mapping to determine

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 ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 The study of the pyrolysis characteristics of oil shale, an important strategic resource, is of great significance for oil shale refining and in situ underground mining. In this study, using the oil shale from Jimsar region of Xinjiang, in combination with thermogravimetric analyzer (TG), Fourier transform infrared spectroscopy (FTIR), and mass ...

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
