Chemical and Biogeochemical Processes at Methane and Other Cold Seeps

Methane is a strong climate-active gas, the concentration of which is rapidly increasing in the atmosphere. Vast methane reservoirs are hosted in seafloor sediments, both dissolved in pore fluids and trapped in gas hydrate. Cold seeps discharge significant amounts of this methane into the ocean. The rate of seabed methane discharge could be orders of magnitude higher than current estimates, creating considerable uncertainty. The extent of methane transfer from the seafloor to the water column and ultimately to the atmosphere is also uncertain. The seepage of methane and other hydrocarbons drives complex biogeochemical processes in marine sediments and the overlying water column. Seeps support chemosynthesis-based communities and impact the chemistry of the water column. Seeps may also play a critical role in ocean acidification and deoxygenation and can be geohazards, as well as a potential energy resource. Unraveling the complex and dynamic interactions and processes at marine seeps is crucial for our understanding of element cycling in the geo- and hydrosphere.

Deep-Buried Large Hydrocarbon Fields Onshore China: Formation and Distribution

This book analyzes the formation and evolution of the giant hydrocarbon reservoirs based on major basins onshore China. It discusses exploration and research advantages of major basins in China, such as Sichuan, Tarim, and Ordos Basins and also systematically analyzes and summarizes the formation conditions, distribution rules, and main controlling factors of deep oil and gas fields. On this basis, it forecasts the exploration prospect of China's onshore deep oil and gas, providing theoretical guidance and technical support for deep oil and gas exploration breakthrough and large-scale reserves growth. This book focuses on the analysis and discussion of hydrocarbon generation mechanism of dee...

The Characteristics and Development Technology Policy of Low Permeability-Tight Sandstone Reservoirs in Fluvial-Delta Systems

This book focuses on the study of low permeability and tight sandstone reservoirs within fluvial delta facies found in the Ordos Basin, Songliao Basin, and Sichuan Basin. It systematically examines the superimposed patterns, geometric forms, and scale characteristics of sedimentary sand bodies within the fluvial delta system. Additionally, it analyzes the impact of seepage barriers such as interlayers and closed faults on fluid flow. The book establishes a sedimentary model for sand bodies in typical sedimentary environments, considering the differences in separation and connectivity caused by the shape, scale, direction, and spatial overlap of different reservoir units and seepage barriers. It investigates the mechanisms of fluid flow controlled by interlayer, plane, and intralayer heterogeneity to understand the fluid flow within the reservoir architecture unit affected by different flow types.

Integrating Artificial Intelligence and Machine Learning with Blockchain Security

Due to its transparency and dependability in secure online transactions, blockchain technology has grown in prominence in recent years. Several industries, including those of finance, healthcare, energy and utilities, manufacturing, retail marketing, entertainment and media, supply chains, e-commerce, and e-business, among others, use blockchain technology. In order to enable intelligent decision-making to prevent security assaults, particularly in permission-less blockchain platforms, artificial intelligence (AI) techniques and machine learning (ML) algorithms are used. By exploring the numerous use cases and security methods used in each of them, this book offers insight on the application of AI and ML in blockchain security principles. The book argues that it is crucial to include artificial intelligence and machine learning techniques in blockchain technology in order to increase security.
