Current status and advancement from high yield and oilfield geothermal energy production: A systematic review

Abstract

This review provides a comprehensive assessment of the current state and advancements in geothermal energy production from enhanced geothermal systems, and the oilfields. As the emphasis on developing a sustainable environment intensifies, it is crucial to use energy sources judiciously. The adoption of renewable energy technologies is essential to establishing energy systems that are significantly more sustainable than the current reliance on fossil fuels. Over the past few decades, research has demonstrated that harnessing geothermal energy and improving the efficiency of existing geothermal systems are both effective strategies for addressing energy challenges. Although geothermal energy, particularly from enhanced geothermal systems, and oilfields has certain limitations relative to other renewable sources, it offers significant advantages by reducing environmental impacts and lowering emissions of harmful gases. The current study, reveals at least 18 enhanced geothermal systems sites have been in operation, with approximately 40 years of development experience with several case studies and pilot projects related to oilfield geothermal energy are in existence. As of 2023, the total installed capacity of geothermal energy worldwide stands at 14,846 megawatts. The past decade has seen significant improvements in geothermal energy extraction techniques. Looking forward, geothermal energy is poised to play a pivotal role in the global energy transition, offering a reliable and low-emission energy source that is essential for achieving long-term sustainability goals.
