Article Abstract
Horizontal well technology is an efficient method of oil and gas exploitation. The goal of increasing oil production and improving productivity can be achieved by increasing the contact area between the reservoir and the wellbore. The presence of bottom water cresting reduces the efficiency of oil and gas production significantly. Autonomous inflow control devices (AICDs) are widely used to delay the influx of water into the wellbore. Two kinds of AICDs are proposed to restrain the bottom water breakthrough during natural gas production. The fluid flows in the AICDs are simulated numerically. The pressure difference between the inlet and outlet is calculated to evaluate the ability of blocking the flow. A dual-inlet design can increase the flow rate of AICDs, thus enhancing the water blocking effect. Numerical simulations show that the devices can block water flowing into the wellbore effectively.

To address the technical challenges of monitoring brine seepage in salt lakes, this study pioneers the application of B isotope tracer to seepage detection, establishing a high-precision monitoring system that provides scientific foundations for precise seepage channel identification and flow field characterization. Systematic laboratory experiments validate the exceptional performance of the B tracer, including ultra-trace detection sensitivity of 10, a stable recovery rate of 92.8-106.

High-quality three-dimensional (3D) simulations can offer a clear understanding of intraoperative anatomical structures, allowing for increases in resectability rates and reductions in postoperative complications. In this video, we present a case of precise surgical resection based on 3D simulation: right trisegmentectomy and caudate lobectomy with portal vein (PV) and IVC reconstruction.

Small intracranial aneurysms (SIAs) (< 5 mm) are increasingly detected due to advanced imaging, but predicting rupture risk remains challenging. Rupture, though rare, can cause devastating subarachnoid hemorrhage. This study analyzed 141 SIAs (101 unruptured, 40 ruptured) using semi-automatic morphological analysis and high-resolution, image-based blood flow simulations from 3D rotational angiography.

With accelerated urbanization, temperature inversion phenomena are becoming more prominent in urban atmospheric environments, playing a very important role in air quality and public health. Despite the widespread literature on the formation and longevity of inversions, little is understood about the measures to mitigate them. Filling this knowledge gap, this work examines the impact of low-level artificial perturbations on near-surface inversions through the use of numerical modeling.

The hydrological extremes, caused by increasing regional extreme precipitation and melting glaciers or snow under climate change, pose a major challenge to reservoir management in Tianshan Mountain Range of China. Modeling and assessment of hydrological extremes are important measures to ensure the safety of reservoir operations and regional water resources. However, insufficient assessment of hydrological extremes faced by reservoirs in Tianshan Mountain Range has limited the development of flood risk assessment and early warning methods for mountain reservoirs.
