The Atlantis massif is a domal submarine seamount close to the mid-Atlantic Ridge at 30 °N. Close to the crest of the Massif, the Lost City hydrothermal field (LCHF) has been active for at least 120,000 years, venting fluids with a temperature of 40-90 °C. 5 km north of Lost City, a ...

Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... Per saperne di più
The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... Per saperne di più
Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... Per saperne di più
Here we aim to advance geomagnetic modeling approaches using COMSOL Multiphysics® software and improve the degree of detail that can be obtained from the measured magnetic field. First, we carried out benchmark tests by comparing the computed results using the widely used analytic ... Per saperne di più
COMSOL® software was used to simulate the conductive heat transfer with phase change in the geological formations encompassed in permafrost surrounding a shallow thaw lake. The purpose of the simulation was to verify the adequacy of COMSOL to model such phenomena by comparing the COMSOL ... Per saperne di più
This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... Per saperne di più
Overpressure-driven hydrofracture zones are pipe-like structures and widespreadly develop in sedimentary basins worldwide. They have the ability to penetrate vertically for multiple kilometers, acting as pathways for fluid on the basin scale. When the hydrofracture zone penetrates the ... Per saperne di più
目前我国页岩气的勘探开发也已取得了突破性成果，但是随着页岩气的开发，仍存在两大问题困扰着科学工作者和现场工程师：（1）页岩气开发过程中的渗透率演化规律尚未摸清；（2）在产气过程中，页岩气在产量上往往呈现出不确定性；针对以上问题，本文发展了基于孔隙结构特征变化的气体微观扩散模型，建立了微观尺度模型用以研究页岩基质有机质与无机质气体流动-微观变形之间的耦合作用。通过离散模型对分析了微观尺度页岩基质不同矿物组分（有机质和无机质）力学参数、孔隙结构、气体流动参数差异对气体微观扩散能力的影响机制，建立了由孔隙结构和流体压力控制的有效扩散模型描述气体微观扩散行为 ...

随着天然气需求的不断增加，页岩气作为一种重要的非常规能源，对于国家能源安全和经济发展具有重要意义。然而，页岩气的有效开采受限于对其储层微观力学特性的深入了解，宏观尺度很难获得页岩各组分的力学性质。因此，我们才用纳米压痕技术来研究页岩微观尺度下的细观力学特性，并基于X射线衍射（XRD）、自动矿物分析系统（TIMA）等先进技术分析，建立微观尺度下的固体变形-气体流动控制模型，分析评估微观产气影响机理，主要研究工作如下： （1）采用纳米压痕实验技术，对页岩进行了不同加载角度下的保持荷载实验以获得页岩微观尺度下的力学参数，如杨氏模量、硬度以及蠕变 ... Per saperne di più
