Abstract: The phrase "soil health" mentions to the entire functionality of the soil as determined by the biological, chemical, and physical characteristics of the soil that are necessary for long-term, sustainable agricultural production by little impact on the environment. The ability of soil to carry out environmental and agronomic tasks, such as biomass productivity, sensitivity to management inputs, and resilience to biotic and abiotic stressors, is referred to as soil health. Since it is impossible to assess directly, soil fertility status and other specific soil parameters, including organic matter content, might be utilized in order to infer the state of the soil. Climate change may have an effect on soil health through temperature changes, salinity, hydrology, and the availability of organic matter. Main characteristics of the soil that are crucial for preserving its health are its desirable texture, structure, and tilt. The impact of several anticipated global change drivers, such as increasing atmospheric carbon dioxide levels, rising temperatures, changed precipitation patterns, as well as nitrogen in the atmosphere accumulation, on the environmental, substance, and organic functions of soil, should be taken into account when describing the condition of soils in connection with changes in the climate.

Abstract: In the advancement of bottom water reservoir development, water breakthrough poses a significant challenge to the productivity of oil and gas wells, underscoring the paramount importance of effective water control strategies. Given the intricate nature of the factors leading to reservoir water breakthrough, a one-size-fits-all approach to water management is non-existent. Rather, tailored water control techniques are necessary to address the diverse causes of this phenomenon. This paper delves into the evolution and application of water control technologies, particularly focusing on the prevalent horizontal well water control methodologies. Horizontal well variable density water control, segmented water control, double horizontal well oil recovery water control, along with advanced solutions such as ICD (Inflow Control Device), ICV (Inflow Control Valve), AICD (Autonomous Inflow Control Device), and AICV (Autonomous Inflow Control Valve) water control systems are comprehensively introduced. Furthermore, center-controlled, mechanical plugging, and chemical plugging water control technologies are also examined in depth, accompanied by a thorough analysis of their respective strengths, limitations, and adaptability to various scenarios. By keeping abreast of both domestic and international trends in horizontal well water control, the future trajectory of this field is forecasted. Emerging as key technologies are novel composite water control systems, dual-purpose water control and sand prevention techniques, and intelligent water control solutions. These advancements promise to revolutionize the management of water breakthrough in bottom water reservoirs, enhancing oil and gas recovery efficiency and sustainability.
