The Occurrence Characteristics and Enrichment Patterns of Shale Oil in Different Lithofacies: A Case Study of the Fengcheng Formation in the Mahu Sag. [PDF]

ACS Omega
The supply of shale oil is of significant importance to the sustainability of energy resources. However, due to the diversity of shale lithofacies, the occurrence characteristics and enrichment patterns of free oil and adsorbed oil remain unclear. Based on this, taking the shale oil reservoir of the Fengcheng Formation in the Mahu Sag as the research ...

Application of Facies Controlled Prestack Inversion Technology in Prediction of Deep Tight Gas in Continental Faulted Basin

Geofluids, Volume 2022, Issue 1, 2022., 2022
It is difficult to predict tight sandstone gas in continental rift basin because of complex deep structure, fast transformation of sedimentary facies, large lateral variation of reservoir thickness, and tight and strong heterogeneity. Based on the petrophysical analysis of logging data, this paper improved the traditional low‐frequency establishment ...

Numerical Investigation of Hydraulic Fracture Propagation Morphology in the Conglomerate Reservoir

Geofluids, Volume 2022, Issue 1, 2022., 2022
The random distribution of gravels makes the conglomerate reservoir highly heterogeneous. A stress concentration occurs at the gravel‐matrix interfaces owing to the embedded gravel and affects the local mechanical response significantly, making it difficult to control and predict hydraulic fracture (HF) propagation.

Genesis and microscopic characteristics of tight reservoirs in the Fengcheng Formation, at the southern margin of the Mahu Sag

Energy Geoscience, 2023
The tight reservoirs of the Fengcheng Formation at the southern margin of the Mahu Sag have strong heterogeneity due to the diversity in their pore types, sizes, and structures. The microscopic characteristics of tight reservoirs and the mechanisms that generate them are of significance in identifying the distribution of high-quality reservoirs and in ...

Source identification and accumulation restoration of complex oil reservoirs in Mahu Sag, Junggar Basin

Energy Exploration & Exploitation, 2023
Oil sources and accumulations in complex oil reservoirs of superimposed basins are difficult to identify and recover because of multiple kitchens and multistage charging processes. Constraining the oil sources and characterizing their accumulation patterns is a critical challenge.

Petrology Characters of Conglomerates in Baikouquan Formation, Mahu Sag, Junggar Basin

Journal of Geoscience and Environment Protection, 2019
Mahu Sag, one of the most oil and gas bearing sags in Junggar basin, is in the northwestern margin of the basin. On gentle slope region of the sag, a serial of large scale coarse fan delta deposits were developed in Triassic Baikouquan Formation. In order to understand the petrology characters of conglomerates in Baikouquan Formation, based on lots
