Summary: Through modern 3D seismic data, researchers have discovered the evolution of deepwater channel systems in the late Miocene stratigraphic sequence in the southern Taranaki Basin, suggesting that anomalous features between channel complexes may be the result of overbank sediment waves. Different interpretations, such as slump scarps and progradational clinoforms, were also presented to enhance the identification of these deepwater depositional elements.

Summary: This study investigates the reservoir characteristics of the Mount Messenger Formation in the deep-water environment of the Kaimiro-Ngatoro Field, utilizing 3D seismic data, core data, and well data to identify lithofacies, sedimentary structures, and depositional environments. The formation is divided into slope fans and basin floor fans, with basin floor fans showing better reservoir qualities. Seismic interpretation reveals multiple horizons, faults, and the presence of hydrocarbons, contributing to a comprehensive understanding of the deep-water turbidite reservoir in New Zealand.

Summary: This study analyzes the morphological character of 123 megaclasts and proposes a new classification scheme based on their morphometric properties using high-quality, three-dimensional seismic reflection data from the deep-water Taranaki Basin offshore New Zealand. The megaclasts can be classified as undeformed, rotated, deformed, and highly deformed based on their internal deformational styles. The study demonstrates that quantitative parameterization of the megaclasts provides important information about their deformational processes and a more complete understanding of megaclast emplacement along continental margins.

Summary: The study reveals that the Triassic Ordos Lake turbidite system is relatively large and supported by continuous sediment supply from extraordinary flood events. In the lacustrine realm, extreme flood events can generate a world-class deep-water turbidite system comparable to its submarine counterparts.

Summary: Research on sediment gravity-flow systems in the Songliao Basin is valuable for understanding sedimentary processes, patterns, and predicting the presence of good sandstone reservoirs. The study identified deep lake channel-levee-lobe and slope fan deposits within six depositional sequences spanning from the Turonian to early Coniacian upper part of the fourth member of the Quantou Formation to the early Campanian second member of the Nenjiang Formation.

Summary: This study investigates the sedimentary mechanisms and depositional architecture of lacustrine turbidite systems under lake-level changes in the Eocene Dongying Depression, Bohai Bay Basin, East China. The results highlight the importance of climate forcing in controlling the depositional differences of lacustrine turbidites during regression stages. The study also provides a new predictive model for deep-water hydrocarbon exploration and production in lacustrine basins worldwide.

Summary: Turbidite fans, formed during deep faulting periods, are important reservoirs for petroleum accumulation in continental basins. This study focuses on the turbidite fans in the gentle slope zone of the Chezhen Depression in the Bohai Bay Basin. The study reveals the common sedimentary types, lithofacies characteristics, and incomplete Bouma sequences in the study area. The findings contribute to the understanding of turbidite fans in continental faulted basins and provide valuable references for exploring unconventional reservoirs.

Summary: Deep-lacustrine systems have been less studied compared to marine systems due to the scarcity of large and continuous outcrops globally. This study examines outcrops and cores from the Ordos Basin in China, revealing the presence of deep-lacustrine slope channels and levee deposits composed of interbedded sandstones and mudstones. The re-interpretation of sandstone-prone deposits in the Yanchang Formation provides insights into the architectural elements in intracratonic lacustrine basins, with implications for hydrocarbon exploration and production.

Summary: The Zhuhai Formation in the Pearl River Mouth Basin contains extensive shelf-edge delta and slope fan deposits in the northern South China Sea. The study systematically documents the depositional architecture and delivery mechanism of sandy deposits from the shelf margin to the lower slope through integrated analysis of well-log, seismic, and core data. Four major depositional facies are identified: shelf-edge incised channels and deltas, amalgamated slump-channel complexes, slope gullies, and slope fan deposits. The channelization and large-scale slumping along the shelf-edge delta front are regarded as the most important dispersal mechanisms delivering sandy sediments across the shelf margin.

Summary: This paper discusses the detailed lithostratigraphy and facies analysis of the Tufiti di Tusa Formation, a deep-marine clastic succession containing volcanic detritus in the late Eocene-early Miocene basin system. The study section is divided into three units, with Unit I and II representing different depositional phases and Unit III representing a stripping depositional phase. The compositional variations between the units suggest changes in sediment supply and tectonic processes.

Summary: The research focused on the three-dimensional evolution of deep-water channel systems and how depositional environments impact channel architecture, analyzing the late Miocene channel complexes in the southern Taranaki Basin, New Zealand. Seismic attributes were used to identify channel bodies and architectural elements, revealing a transition in sinuosity patterns and stacking facies within the channel systems. The findings suggest a shift from sediment bypass to vertically aggrading channel systems due to changes in the shelf-slope gradient.

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.
