Abstract

Deep geothermal energy, carbon capture and storage, and hydrogen storage hold considerable promise for meeting the energy sector's large-scale requirements and reducing CO 2 $\text{CO}_2$ emissions. However, the injection of fluids into the Earth's crust, essential for these activities, can induce or trigger earthquakes. In this paper, we highlight a new approach based on reinforcement learning (RL) for the control of human-induced seismicity in the highly complex environment of an underground reservoir. This complex system poses significant challenges in the control design due to parameter uncertainties and unmodeled dynamics. We show that the RL algorithm can interact efficiently with a robust controller, by choosing the controller parameters in real time, reducing human-induced seismicity, and allowing the consideration of further production objectives, for example, minimal control power. Simulations are presented for a simplified underground reservoir under various energy demand scenarios, demonstrating the reliability and effectiveness of the proposed control–RL approach.

人工智能驱动的地球地下可再生能源可持续开采方法,同时最大限度地减少地震活动
深层地热能、碳捕获和储存以及氢储存在满足能源部门的大规模需求和减少排放方面具有相当大的前景。然而,对这些活动至关重要的流体注入地壳,可能诱发或引发地震。在本文中,我们重点介绍了一种基于强化学习(RL)的新方法,用于控制地下水库高度复杂环境下的人为地震活动。由于参数的不确定性和未建模的动力学特性,这种复杂的系统给控制设计带来了巨大的挑战。研究表明,RL算法可以通过实时选择控制器参数,减少人为引起的地震活动,并允许考虑进一步的生产目标,例如,最小的控制功率,与鲁棒控制器有效地交互。以一个简化的地下水库为例,对不同能源需求情景进行了仿真,验证了所提出的控制- rl方法的可靠性和有效性。

期刊介绍: The journal welcomes manuscripts that substantially contribute to the understanding of the complex mechanical behaviour of geomaterials (soils, rocks, concrete, ice, snow, and powders), through innovative experimental techniques, and/or through the development of novel numerical or hybrid experimental/numerical modelling concepts in geomechanics. Topics of interest include instabilities and localization, interface and surface phenomena, fracture and failure, multi-physics and other time-dependent phenomena, micromechanics and multi-scale methods, and inverse analysis and stochastic methods. Papers related to energy and environmental issues are particularly welcome. The illustration of the proposed methods and techniques to engineering problems is encouraged. However, manuscripts dealing with applications of existing methods, or proposing incremental improvements to existing methods – in particular marginal extensions of existing analytical solutions or numerical methods – will not be considered for review.
