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.

    Shale Fracturability Graphic Template Based on Mixed Analytic Hierar-chy Process and Mutation Theory

    Sichen Li, Dehua Liu, Liang Cheng, Pan Ma

    Abstract Due to the depletion of conventional energy reserves, there has been a global shift towards non-conventional energy sources. Shale oil and gas have emerged as key alternatives. These resources have dense and heterogeneous reservoirs, which require hydraulic fracturing to extract. This process depends on identifying optimal fracturing layers, also known as ‘sweet spots’. However, there is currently no uniform standard for locating these sweet spots. This paper presents a new model for evaluating fracturability that aims to address the current gap in the field. The model utilizes a hierarchical analysis approach and a mutation model, More >

    Abstract China’s unconventional gas fields have a large number of low-productivity and low-efficiency wells, many of which are located in remote and environmentally harsh mountainous areas. To address the long-term stable production of these gas wells, plunger-lift technology plays an important role. In order to fully understand and accurately grasp the drainage and gas production mechanisms of plunger-lift, a mechanical model of plunger-liquid column uplift in the plunger-lift process was established, focusing on conventional plunger-lift systems and representative wellbore configurations in the Linxing region. The operating casing pressure of the plunger-lift process and the calculation method… More >

    Abstract This study investigates the heat dissipation mechanism of the insulation layer and other plane insulation layers in the polar drilling rig system. Combining the basic theory of heat transfer with the environmental requirements of polar drilling operations and the characteristics of polar drilling processes, we analyze the factors that affect the insulation effect of the drilling rig system. These factors include the thermal conductivity of the insulation material, the thickness of the insulation layer, ambient temperature, and wind speed. We optimize the thermal insulation material of the polar drilling rig system using a steady-state method… More >

    Abstract Horizontal well-stimulation is the key to unconventional resource exploration and development. The development mode of the well plant helps increase the stimulated reservoir volume. Nevertheless, fracture interference between wells reduces the fracturing effect. Here, a 2D hydro-mechanical coupling model describing hydraulic fracture (HF) propagation is established with the extended finite element method, and the effects of several factors on HF propagation during multiple wells fracturing are analyzed. The results show that with an increase in elastic modulus, horizontal principal stress difference and injection fluid displacement, the total fracture area and the reservoir stimulation efficiency are More >

    (This article belongs to the Special Issue: Hydraulic Fracturing Theory and Application for Geo-energy Development)
    Abstract Multistage multi-cluster hydraulic fracturing has enabled the economic exploitation of shale reservoirs, but the interpretation of hydraulic fracture parameters is challenging. The pressure signals after pump shutdown are influenced by hydraulic fractures, which can reflect the geometric features of hydraulic fracture. The shutdown pressure can be used to interpret the hydraulic fracture parameters in a real-time and cost-effective manner. In this paper, a mathematical model for shutdown pressure evolution is developed considering the effects of wellbore friction, perforation friction and fluid loss in fractures. An efficient numerical simulation method is established by using the method… More >

    Energy Engineering, Vol.120, No.11, pp. 2503-2516, 2023, DOI:10.32604/ee.2023.041803
    (This article belongs to the Special Issue: Hydraulic Fracturing Theory and Application for Geo-energy Development)
    Abstract The fracturing process of sandstone is inherently complex due to its loose internal structure and deformation adaptability. Liquid nitrogen pre-injection has emerged as a promising approach to damage reservoir rocks, effectively reducing fracture pressure and establishing intricate fracture networks, thus offering a potential solution for reservoir reconstruction. To unravel the fundamental mechanisms governing sandstone fracturing behaviors following liquid nitrogen pre-injection, sandstone fracturing experiments were conducted under varying durations of liquid nitrogen injection, rock temperature, and in-situ stress conditions. The experiments showcased the evolution of injection pressure and fracture characteristics under different testing conditions, complemented by… More >
