Summary: This study conducted a time-lapse seismic experiment to monitor a reactivated fault within the Opalinus clay formation at the Mont Terri Rock Laboratory. The measured changes in P-wave velocity were related to the opening of the fault damage zone, providing insights into changes in permeability within the fault zone. This research is important for predicting, detecting, and preventing CO2 movement.

Summary: Automatic gas chimney classification methods utilize selected seismic attributes as inputs for machine-learning algorithms. This paper introduces an algorithm for gas chimney detection and extraction based on the amplitude attribute. The method involves a feature extraction process (MODWT) and a standard machine-learning algorithm (BiLSTM). The results demonstrate the successful automatic detection and extraction of gas chimneys from 3D seismic data using a single attribute.

Summary: The Barents Sea has experienced intense erosion due to uplift and glaciation, leading to hydrocarbon leakage. The primary factors controlling gas leakage include erosion amount, distribution, and timing of glaciation. Analyzing the results, approximately 20% of oil and gas was lost during the first deglaciation episode, followed by an additional 15% decrease in gas due to seal breach.

Summary: This study investigates the contamination of subsurface soil by volatile organic compounds (VOCs), focusing on petroleum hydrocarbon compound (PHC) as a typical VOC. A one-dimensional analytical model is developed to simulate the diffusion and oxygen-limited biodegradation of PHC vapor in homogeneous soil. The migration of PHC vapor is found to occur in three stages: pure aerobic zone stage, aerobic-anaerobic zones co-existence stage, and steady-state stage. The proposed analytical model should be applied in scenarios where the transient effect is significant, such as high source concentration, deep contaminant source, high biodegradation capacity, and high water saturation.

Summary: This paper discusses the controversy surrounding the role of geological carbon storage (GCS) in mitigating climate change. By proposing a rock physics-based joint data assimilation model and conducting experiments using CASSM data and wellbore pressure monitoring data, the study shows that a joint monitoring system can provide more accurate estimates of gas saturation and reservoir pressure changes compared to a single monitoring tool.

Summary: The paper is based on the concept of the renewability of oil and gas resources, aiming to estimate the natural replenishment rate of reservoirs using the Bibieybat oil and Garadag gas condensate fields as examples. The study shows that as a field develops, the recoverable hydrocarbon fluids are compensated by their natural inflow, leading to production stabilization.

Summary: Governments have implemented a cap on greenhouse gas emissions to protect the environment. This study examines the optimal production strategy for producers under this policy. The results show that remanufacturing is the preferred strategy when production must be completed in a regulated region. However, if production transfer is allowed, partial production transfer becomes the optimal strategy when the emissions cap exceeds a certain threshold.

Summary: This paper introduces a characterization parameter called effective displacement flux to describe the flushing intensity, and develops a new numerical simulator based on the black oil model, which considers the rock-fluid properties as functions of the effective displacement flux. A conceptual reservoir model is established to validate the effective characterization of time-varying mechanisms. The new simulator is then applied to an actual waterflooding reservoir simulation, demonstrating its assistance in history matching and improvement in simulation accuracy.

Summary: The study focuses on the effects of interactions in natural gas/water/rock system on hydrocarbon migration and accumulation process in tight formation. Both macroscopic and microscopic investigations are conducted using formation fluorescence tests, production data analysis, mathematical analysis, and experimental methods. Numerical simulations are utilized to visualize and quantify the effects, showing that an increase in geological temperature and pressure leads to changes in contact angle and interface tension, ultimately affecting the charging threshold in rock formations.

Summary: Surficial CO2 efflux surveys are used to identify hydrocarbon source zones in contaminated aquifers and estimate hydrocarbon biodegradation rates. Radiocarbon is used to differentiate between CO2 from petroleum degradation and natural soil respiration for quantifying contributions to total CO2 efflux. Comparison of methods for collecting CO2 gas samples showed that static chambers and shallow soil gas probes provide reliable estimates of CO2 effluxes from contaminant degradation. Results showed that all methods agreed within a factor of <2.3 for inferred NSZD rates.

Summary: Hydrogen has great potential as an energy carrier for decarbonizing industries and providing heat for buildings as well as fuel for trains, buses, and heavy trucks. Underground geologic storage of hydrogen offers low-cost storage capacity and buffer capacity to meet changing electricity demands or power supply disruptions. However, there are technical challenges preventing its large-scale use as an energy carrier.

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.
