Summary: The use of gels in oil production processes is a common practice worldwide, with continued development and increasing publications and patent activity. Various gel technologies, including inorganic, organic, and hybrid gels, as well as foam, gel-forming, and gel-dispersed systems, are employed in processes such as hydraulic fracturing and conformance control. The introduction of microscale and nanoscale additives allows for precise control of structural and mechanical properties, making gels indispensable tools for oil engineers.

Summary: This article systematically summarizes the horizontal well fracturing technology for shale oil and gas reservoirs abroad since the 13th Five-Year Plan, and elaborates on new features in 3D development of stacked shale reservoirs, small well spacing and dense well pattern, horizontal well re-fracturing, fracturing parameters optimization and cost control. Based on the requirements for horizontal well fracturing technology in China, the technological progress in multi-fracture propagation simulation, horizontal well frac-design, electric-drive fracturing equipment, soluble tools and low-cost downhole materials, and factory-like operation are summarized. The article also suggests strengthening research and development in seven aspects for the 14th Five-Year Plan.

Summary: The research found that a 5-meter horizontal fracture length in the hydrate reservoir significantly increased gas production when the horizontal well was located in different areas within the gas hydrate-bearing layer. Increasing the fracture length from 5 to 20 meters only slightly increased gas production. Additionally, the promotion effects of horizontal fractures on gas production varied based on the location of the horizontal well within the reservoir.

Summary: This research examines media portrayals of unconventional oil and gas development's (UOGD) economic and environmental impacts. It reveals that selective attention to media coverage of the impacts can influence issue attitudes. The study also finds that political ideology plays a role in driving such attention, and that the attention given to different types of impacts predicts public support for UOGD.

Summary: Anthropogenic noise from natural resource extraction, particularly drilling noise, had a greater negative impact on grassland songbirds' habitat use and productivity compared to oil well operating noise. Effective mitigation strategies should focus on managing both noise and above-ground infrastructure to reduce impacts on wildlife.

Summary: This study evaluates the potential of silica sand samples collected from different areas in the Eastern and Western Deserts of Egypt to be used as frac sand proppants. The results show that the samples from Wadi El-Dakhal have higher quality compared to those from Wadi Qena, and the samples from Gabal El-Dist can be utilized in shallow depths. The assessment testing confirms that the samples meet the standard requirements.

Summary: This study investigates the behavior of hydraulic fracture propagation in the tight oil reservoirs of Fuyang and Gaotaizi in the Daqing Oilfield. The research shows that stress differences and rock mechanical parameters play key roles in controlling fracture penetration. Additionally, flow rate and viscosity of the fracturing fluid have significant impacts on fracture progression.

Summary: Recent developments in multi-stage hydraulic fracturing for shale oil reservoirs are focusing on shorter cluster spacing and larger number of clusters, with the aim of improving stimulation performance while reducing costs. The study introduces the effective XLE completion method for enhancing perforation cluster efficiency and discusses the impact of various parameters on cluster effectiveness. The research results offer theoretical guidance for optimizing XLE completion in geological reservoirs.

Summary: The research aims to develop a risk framework using data and expert knowledge for quantitative and qualitative analysis of risk for hydraulically fractured wells in the UK and Canada. New fault trees were developed to determine probabilities of cement failure in vertical and horizontal directions, as well as the probability of groundwater migration during well injection stage. The framework can be extended to assess risk across all stages of well development, narrowing the gap between modeled and actual probabilities.

Summary: It is of great significance to predict the production rate and estimate the ultimate recovery for the optimization of shale gas development. A novel approach using XFEM is proposed to simulate the processes of hydraulic fracturing and gas production, revealing that proppant size has a dominant influence on gas production, followed by proppant concentration, shale formation viscosity, proppant Young's modulus, and shale formation Young's modulus.

Summary: Oil and gas production generate a large amount of brine wastewater containing various contaminants. The improper disposal of this wastewater may contaminate freshwater aquifers and impact drinking water sources. This study found that chlorinated oil and gas wastewater formed high levels of disinfection byproducts, including trihalomethanes exceeding regulatory limits, while chloraminated wastewater had higher formation of iodinated disinfection byproducts and haloacetamides. These findings highlight the potential adverse impact of oil and gas wastewater on downstream drinking water supplies and public health.

Summary: This research provides a comprehensive analysis of lightweight proppants. It covers the research advances made on lightweight proppants in both scientific literature and commercial proppants manufacturers. The paper discusses three varieties of lightweight proppants: hollow/porous proppants, surface-modified proppants, and proppants derived from low-density materials. Field application of lightweight proppant in scale inhibition, gravel packing, and hydraulic fracturing is also summarized. Furthermore, the research highlights the future research directions and obstacles of lightweight propellants.
