Summary: This research aims to understand the facies, facies association, and sequence stratigraphic framework of the Bima Formation in the Upper Benue Trough. The formation is composed of three facies associations and four facies successions, and is divided into four depositional sequences. The sedimentation processes in the Bima Formation are controlled by climate, tectonic subsidence, and uplift.

Summary: This study investigates the relationship between depositional facies, diagenesis, and reservoir quality of the Campanian-Maastrichtian Gombe Sandstone in the Northern Benue Trough, NE Nigeria. It employs a multi-technique approach to analyze thin-section petrography, scanning electron microscopy, and X-ray diffraction data. The study reveals that the sandstone is primarily composed of arkosic and subarkosic material, and deposited in different sub-environments. The interdistributary tidal bar/channel sandstones exhibit the best reservoir quality, while the lower delta front/prodelta, upper delta front/mouth bar, and distributary channel sandstones have poorer reservoir quality.

Summary: This study investigates the source rock potential, sequence stratigraphy, and hydrocarbon reservoir characterization of the Otumara field in the Niger Delta. Integrated 3D seismic, wireline log analysis, and basin modeling techniques were used. The results show that the Upper Akata Formation is the primary source rock for hydrocarbons, despite higher total organic carbon (TOC) percentage in the Agbada Formation. Sequence stratigraphy analysis identified second-order supercycles in the studied well. The field has two large net pays with high-quality reservoir facies, and the reservoirs are faulted by a series of growing faults. Petrophysical parameters, porosity, permeability, shale volume, and hydrocarbon saturation were also estimated. This case study highlights the importance of using wireline logs for organic richness estimation and sequence stratigraphy analysis in clastic sediments.

Summary: This study focuses on the diagenetic alterations and their impact on the porosity evolution of the Cretaceous Bima Sandstone in NE Nigeria. The results indicate that mechanical compaction and quartz cementation have significantly modified the porosity, while primary depositional features have a smaller impact. The findings of this study are important for reducing exploration risks in fluvial reservoirs.

Summary: During the synrift stage of the Liaodong Bay sub-basin, strike-slip motion within the Tan-Lu Fault Zone played a significant role in local structural evolution, leading to abundant structural deformations. However, the exact role of TLFZ in the evolution of the Bohai Bay Basin remains unclear.

Summary: This study focused on sequence stratigraphy and seismic facies in the Central Taranaki basin, identifying four regional seismic sequences and boundaries representing unconformities. Analysis indicated a new perspective surface between the upper and lower Giant formation due to seawater encroachment. The study proposed a new sequence stratigraphy framework and discussed potential hydrocarbon accumulations, suggesting the SA-Middle Giant Formation (SEQ3) as a potential trap.

Summary: This study analyzed coal samples from the Benue Trough Basin in Nigeria using various techniques and found that the coal samples had lower elemental contents and mainly consisted of minerals such as clays and quartz. The coal-forming marsh experienced relatively mild redox conditions and showed evidence of a significant freshwater environment, with differences in thermal reactivity among samples.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.

Summary: This study investigates 13 submarine seamounts in the southern Andaman volcanic arc and observes evidence of hydrothermal activity in one of the seamounts. The evidence includes plumes rich in dissolved gases, live chemosymbiotic organisms, and the deposition of neoforming minerals. These observations suggest the development of a new hydrothermal field in the least explored Andaman Sea.

Summary: This study employs an integrated depositional and sequence stratigraphic approach to assess the control of diagenesis on reservoir porosity of a hybrid-energy delta system. The study focuses on the Barik Formation in the Haushi-Huqf region of Central Oman, which represents a highstand system tract of a hybrid-energy delta. The assessments reveal that the reservoir porosity is controlled by various degrees of diagenetic processes, including mechanically infiltrated clays and kaolinitization of silicate grains.

Summary: Oilfield brines are a significant alternative lithium resource. This study investigates the metallogenic characteristics and enrichment process of oilfield brines from the Jianghan Basin, central China using chemical and multi-isotope data. The results suggest that lithium enrichment in these brines is the result of interaction with clastic host rocks and dilution by meteoric water.

Summary: Due to the lack of deep wells in the broader region, studying mud volcanic deposits can improve the geological understanding of the Mediterranean Ridge. In this study, biostratigraphic and geochemical analyses were performed on mud breccia deposits from five Mud Volcanoes in the central MR. The results indicate the origin of these deposits and provide insights into the source rock potential. Seismic data is also used to determine the distribution of major lithostratigraphic formations.
