Summary
Recent years have seen great advances and successes in fracturing with horizontal wells in unconventional reservoirs. Using fracturing operations, hydraulic fractures are created in formations by injecting viscous high-pressure fluid through a wellbore. Large contact area with formations through fractures changes the flow resistance in porous media. Proppant with different strengths or sizes are generally added to prevent the fracture from closure. Hydraulic fracturing also shows its application prospects in enhanced geothermal systems, waste disposal, CO2 utilization, and energy storage.
To design an optimized fracturing design, we need to understand the essential mechanism of fracturing, such as fracture growth, proppant transport, fracture closure, fracture diagnosis, and production analysis, etc. These issues are unclear yet and critical to optimizing fracturing design for Geo-energy development. Therefore, we plan to propose this special issue in Energy Engineering.
This Special Issue on “Hydraulic Fracturing Theory and Application for Geo-energy Development” will collect research articles and comprehensive reviews focused on the aforementioned topics.
Topics include, but are not limited to:
1. Geomechanics in fracturing, including the rock mechanical properties, in-situ stress determination, pore pressure prediction, and wellbore stability, etc.
2. Stimulation methods for geothermal energy development, including multi-well fracturing, diverting fracturing, re-fracturing, thermal shock fracturing, etc.
3. Fracturing materials for geo-energy, including low-friction and low-damage fracturing fluids, new temporary plugging agents, and new proppant materials.
4. Multi-phase transport mechanism, including fluid flow in porous media, slurry transport in simple or complex fractures during the whole fracturing process.
5. Fracture interpretation for fracture monitoring, including pressure, temperature, distributed strain/temperature by optical fiber, microseismic, etc.
Energy production analysis, including geothermal energy production analysis, petroleum production analysis, and flowback optimization for production enhancement.
