Summary: This study investigates how submarine canyon systems can focus sub-surface fluid using a high-quality 3D seismic volume from offshore Canterbury Basin, New Zealand. The results reveal multiple pockmarks, eroded gullies, and intra-slope lobe complexes associated with the Waitaki Submarine Canyon. The findings suggest that subsurface fluid may migrate from Cretaceous strata through shallow channel-fill deposits and lobes to seep out through the canyon and associated gullies.

Summary: Predicting whether turbidity currents are erosional or depositional remains challenging. By combining observations from submarine channel morphology with a new sediment transport model, this study derived thresholds for net erosional, equilibrium, or net depositional flow. The results show that thicker flows carrying well-sorted suspensions can bypass sediment more effectively than thinner flows carrying more poorly-sorted suspensions.

Summary: This study provides a detailed sedimentological, stratigraphic and depositional model for the lower Whakataki Formation, revealing that the turbidite successions were deposited as dilute low-density turbidity currents transporting sediment downslope. The textural and compositional immaturity, combined with the high carbonaceous and carbonate content of the clastic sediments, indicates a proximal detrital input.flows entering the structurally confined basin were deflected to the north-northeast, producing paleoflow along the basin axis and represent deposition in the early stages of trench-slope basin development.

Summary: The depth of the reservoir causes uncertainty in predicting reservoir quality due to the suppression of high-frequency seismic amplitudes. Seismic data, when used in conjunction with existing data, can provide more accurate results for hydrocarbon prospect identification. This study analyzed the post-drill geophysical characterization of two exploratory wells in the Cauvery Basin and developed a checklist for in-depth study of seismic and well data to discover prospects and reduce risks.

Summary: Through reflection seismology and existing geological observations, this study constructs cross sections depicting the tectono-stratigraphic framework and evolution of the East Junggar Basin and adjacent mountain belts. The results show that the basin is characterized by horsts, grabens, and a south-dipping monocline, with thicker sequences of Cretaceous-Quaternary strata in the southern portion. The overall tectono-stratigraphic framework of the basin is a product of tectonic activity along the basin-mountain interfaces since the late Paleozoic.

Summary: Changes in sedimentary profiles and stratigraphic architecture over time in lake basins can serve as markers of climate changes in terrestrial palaeoenvironments. The Ales-Saint-Chaptes-Issirac saline lake system from late Eocene to early Oligocene has been reconstructed, revealing three distinct depositional models. The development of transgressive-regressive cycles in response to regional tectonics and climate change impacted the depositional architecture of Palaeogene, syn-rift, saline lake basins in Western Europe.

Summary: The coastal zone is economically important and experiences increasing development and activities. Tsunamis, often caused by oceanic earthquakes, pose a significant threat to coastal areas, as demonstrated by the 2004 Andaman tsunami in Malaysia. This study investigates the potential seismic activities and simulates Manila Trench earthquake-induced tsunamis of different intensities on the East Coast of Peninsular Malaysia. Findings reveal that a Mw 9.0 earthquake results in the most disastrous effects, with Kelantan experiencing the highest inundation depth of 4.0 m in Pasir Puteh and Terengganu experiencing the highest inundation depth of 6.0 m in Kuala Terengganu. Mitigation measures and evacuation plans can be improved based on these findings to minimize property and life losses.

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 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.
