Title : Simulation of fluid flow in the enhanced geothermal system and coupled thermal hydro-mechanical modeling
Abstract:
Emphasizing their integration to maximize energy output, we will explore the complex interaction between Enhanced Geothermal Systems (EGS) and heavy oil reserves during the presentation. The conversation will start with an overview of EGS, a rather recent but rapidly rising energy source's importance within the framework of renewable energy. Although geothermal energy is becoming more and more popular, crude oil is still the main fuel used hence innovative technologies are needed to harmonize these energy systems for effective generation of steam, oil, and electricity.
The fundamental focus of the talk will be on a three-dimensional, three-phase numerical model meant to replicate steam injection in heavy oil reservoirs. This model incorporates a new control equation catered to the thermal fluid characteristics of heavy oil reservoirs, therefore addressing the difficulties of heat and mass transport post-EGS fracturing. This equation uses a nonlinear mechanics model of elasticity and plasticity in sand fractures and matrices to consider the dynamic conditions during heavy oil steam flooding.
Using both rectangular and circular fracture models, we will investigate the application of the finite volume approach to replicate EGS water-flood recovery. This section of the work generates a coupled mathematical model for EGS heat removal and steam injection flooding in heavy oil, therefore producing an effective numerical simulation framework. We will emphasize how well this model designs and maximizes the co-development of heavy oil reserves and EGS.
The sensitivity and optimization study of EGS under several conditions—such as well spacing, injection volume, temperature, and reservoir permeability—will occupy a good share of the presentation. These studies seek to meet thermal energy needs and improve heat extraction efficiency. Real-world EGS field examples will be used to apply the outcomes of these research, therefore illustrating how sensitivity analysis enhances conventional field optimization results.
We will also go over how best to identify ideal well spacings using simulations, stressing the part horizontal wells play in secondary recovery for both systems. First running turbines to generate energy, the procedure entails injecting surface water to create steam. With another well drawing the oil, the leftover steam is subsequently used to improve heavy oil flow in a horizontal well.
Additionally, discussed will be the application of reservoir modelling tools from Computer-Modelling Group, Inc.'s (CMG) for operations planning and forecasting. These instruments enable the prediction of technical and engineering results, therefore guaranteeing consistent output of steam, oil, and energy. Developed mathematical models in this work will be presented to show characteristics like initial concentration, fracture length, surface water injection rate, steam generation, reservoir energy, and oil production.
Finally, under stressing the need of integrated modelling and simulation to maximize energy production and improve the viability of renewable energy sources in combination with conventional fuels, the presentation will offer a thorough review of the synergistic potential between EGS and heavy oil recovery systems.

Audience members can employ the integrated EGS and heavy oil recovery approaches to construct more efficient energy producing systems, therefore optimizing resource utilization and improving project outcomes. By simulating complicated reservoir interactions using the explored numerical models and finite volume methodologies, they can improve forecasting accuracy and decision-making. Applying sensitivity and optimization analysis techniques can help reservoirs to be managed more efficiently, thereby optimizing heat extraction and satisfying energy needs sustainably. By using CMG simulation tools, one will be able to better forecast and plan operations, hence lowering uncertainty and strengthening project planning.
Effective resource management and well-considered designs can result in notable cost savings during the development as well as the operational stages. Combining conventional and renewable energy sources helps the shift to more sustainable energy systems, therefore lowering the carbon footprint. The audience will become more competent in their domains by acquiring thorough technical knowledge in nonlinear mechanics, heat transfer, and mass transfer in reservoir systems. Enhanced simulation and forecasting powers contribute to early identification of possible problems, so enabling proactive risk management and guaranteeing project success.
Indeed, this study offers a strong structure for other faculty members to increase their output of research or instruction. Rich material for academic investigation and curriculum creation comes from the combination of EGS with heavy oil recovery, the advanced numerical modeling approaches, and sensitivity and optimization analysis application. Using these approaches, faculty members can investigate fresh directions of engineering design, sustainability, and energy resource management.
The approaches covered clearly offer a foundation for planning and optimizing energy systems, hence lowering complexity and raising efficiency. Better planning and execution follow from designers' accurate prediction of system behaviors made possible by the use of advanced simulation tools and techniques. Understanding how to combine EGS with heavy oil recovery will help designers create more complete and sustainable energy generating systems that fit with contemporary energy targets. -
