Multi-scale characterization of unconventional tight carbonate reservoir: Insights from October oil filed, Gulf of Suez rift basin, Egypt

Ahmed E. Radwan et al.

Summary: The Radwany Formation in the Gulf of Suez region has been newly identified as a potential reservoir rock with a combination of depositional and diagenetic processes creating various porosity types. Petrophysical evaluations and geochemical analysis have indicated the presence of unconventional and conventional hydrocarbon resources in this formation, particularly in the basal part, making it a valuable area for exploration. The study also highlights the importance of understanding the link between sediment microfacies and petrophysical parameters for predicting hydrocarbon potential in the area.

Experimental investigation on gas permeability in bedding shale with brittle and semi-brittle deformations under triaxial compression

Mingliang Liang et al.

Summary: This study investigated the stress-strain behavior, failure deformation, and gas permeability changes in shale under compressive stress induced failure. The results showed that shale exhibits brittle or semi-brittle responses to peak strength load at different angles of pre-existing bedding, and the gas permeability increased after failure deformation. The pre-existing structure of shale influences its mechanical behavior and gas permeability, which is significant for shale gas exploration and development in areas with complex tectonic structures.

Use of rock-physics analysis of well logs to determine compaction history of Cretaceous shales in the Rovuma basin, Offshore Mozambique

Oscar J. Nhabanga et al.

Summary: This study examined Cretaceous shales from the Rovuma basin gas province, analyzing their brittleness and ductility within the framework of acoustic impedance limits. Significant sensitivity to pressure was observed, with some onset of chemical compaction affecting the elastic properties.
