👉 The step fluid, also known as the stepwise or step-flow geothermal system, is a type of geothermal reservoir characterized by its unique structure. It forms in tectonically active regions where hot, buoyant fluids migrate upwards through permeable rock layers, eventually encountering impermeable barriers that trap the hot water or steam. This creates a network of interconnected fractures and faults, allowing for the movement of heat-rich fluids from deep within the Earth's crust to shallower levels. The step fluid then rises through these pathways, often forming distinct, discrete reservoirs that can be accessed and utilized for geothermal energy production.
