Development of Smart Oil and Gas Fields with Multi-energy Synergy of Wind, Solar, Geothermal, and Energy Storage
Abstract
In the context of carbon peaking and carbon neutrality as well as the construction of a new energy system, the integrated development and intelligent regulation of fossil energy with new energy resources such as wind, solar, and geothermal energy has become a new pattern for the future energy system. The oil and gas industry is undergoing digital and intelligent transformation, and the development of smart oil and gas fields will reduce exploration and development costs and increase social and economic benefits. This study elucidates the concept and implications of smart oil and gas fields with multi-energy synergy and the critical role of new smart oil and gas fields in enhancing oil and gas reserves and production and in promoting the green, low-carbon, and intelligent transformation of the oil and gas industry. It reviews the current development status of the wind-solar-geothermal-energy storage multi-energy synergy system, the integration of oil and gas fields with the multi-energy synergy system, and the smart oil and gas fields. The study also identifies the challenges and key issues faced by the development of smart oil and gas fields in China. It summarizes future scenarios for smart oil and gas fields with multi-energy synergy: (1) utilization of green electricity, (2) new geothermal systems for thermal recovery of abandoned heavy oil reservoirs, (3) production optimization of oil well clusters based on wind/solar power microgrids, (4) in-situ conversion of natural gas and utilization of associated gas for power generation, (5) comprehensive energy management systems for efficient and low-carbon oil and gas production, and (6) intelligent collaboration and optimization of electricity, geothermal energy, and hydrogen energy storage. The core output of the construction of smart oil and gas fields with multi-energy synergy is low-carbon oil fields and super energy basins. Under the premise of ensuring oil and gas production, future development should focus on supplementing fundamental shortcomings, increasing technological advantages, strengthening application capabilities, and achieving independence, thereby achieving breakthroughs in key core technologies to form practical development solutions.
