Description

An enhanced method for evaluating the static connectivity of reservoirs using pressure coefficient-depth plots, by Geng Qian, Haifeng Yang, Dayong Guan, Jinghan Wang, Junpei Yue, and Meng Zhao. Pressure-depth profiles have been a cornerstone in investigating static reservoir connectivity and compartmentalization since the advent of repeated formation testing tools in the 1970s. This paper presents an enhanced style of plotting pressure coefficients against depth.

Undoing the paradigm of lithofacies control on carbonate reservoir properties through advanced rock typing, by Ousmane Mangane, Jeroen Kenter, Tarek Mecheri, Jean Borgomano, and Christophe Nussbaumer. Common carbonate rock-typing methods estimate statistical relationships between geological parameters and the core-to-log domain and distribute the resulting petrophysical rock types in reservoirs. The advanced rock-typing presented in this paper combines electrofacies, pore types from core and logs, and statistically relevant depositional attributes to define highly predictable petrophysical rock types.

Quantitative sequence stratigraphy applied to the Barremian-lower Aptian Urgonian carbonates deposited in Provence (southeastern France), by Mickael Barbier, Jean Borgomano, Philippe Leonide, Gerard Massonnat, Charles Danquigny, and Jean-Louis Lesueur. Sequence stratigraphy is an essential tool for interpreting and predicting carbonate sedimentary systems architecture. The study explores advanced quantitative stratigraphy that offers a new perspective compared to traditional sequence stratigraphy.

Tectonic-sedimentary responses to major geological events, source rock formation mechanisms, and resource potential at depths greater than 10,000 m in the cratonic basins of China, by Guangyou Zhu, Jiakai Hou, Rong Ren, Hua Jiang, Bin Zhang, Yinghui Cao, Tingting Li, Kun Zhao, Zhiyao Zhang, and Yifei Ai. The study of the tectonic-sedimentary responses to geological events is significant for identifying the development mechanism of ultradeep source rocks and revealing the potential of oil and gas resources. The authors detail the mechanisms of biological recovery and organic matter accumulation under the warming conditions during the interglacial period by nitrogen isotopes.

Brittle deformation and hydrothermal alteration in the Barra Velha Formation, Santos Basin, offshore Brazil, by Rodrigo dos Santos Maia Correa, Bruno Carvalho, Estibalitz Ukar, Stephen E. Laubach, Andre L. S. Pestilho, Andras Fall, Toti Larson, Daniel Stockli, Lisa Stockli, Volker Leuders, Samuel Niedermann, and David A. Banks. The Barra Velha Formation is a prolific Aptian oil and gas producer located in the Santos Basin, Brazil. The authors used structural core description, petrography, geochemistry, and geochronology to show evidence from drill cores that the formation was affected by several events of brittle deformation and interacting hydrothermal alteration.
