    A Chart-Based Diagnostic Model for Tight Gas Reservoirs Based on Shut-in Pressure during Hydraulic Fracturing

    Mingqiang Wei, Neng Yang, Han Zou, Anhao Li, Yonggang Duan

    Abstract A precise diagnosis of the complex post-fracturing characteristics and parameter variations in tight gas reservoirs is essential for optimizing fracturing technology, enhancing treatment effectiveness, and assessing post-fracturing production capacity. Tight gas reservoirs face challenges due to the interaction between natural fractures and induced fractures. To address these issues, a theoretical model for diagnosing fractures under varying leak-off mechanisms has been developed, incorporating the closure behavior of natural fractures. This model, grounded in material balance theory, also accounts for shut-in pressure. The study derived and plotted typical G-function charts, which capture fracture behavior during closure.

    Estimated Ultimate Recovery and Productivity of Deep Shale Gas Horizontal Wells

    Haijie Zhang, Haifeng Zhao, Ming Jiang, Junwei Pu, Yuanping Luo, Weiming Chen, Tongtong Luo, Zhiqiang Li, Xinan Yu
    FDMP-Fluid Dynamics & Materials Processing, DOI:10.32604/fdmp.2024.053496
    (This article belongs to the Special Issue: Fluid and Thermal Dynamics in the Development of Unconventional Resources II)
    Abstract Pressure control in deep shale gas horizontal wells can reduce the stress sensitivity of hydraulic fractures and improve the estimated ultimate recovery (EUR). In this study, a hydraulic fracture stress sensitivity model is proposed to characterize the effect of pressure drop rate on fracture permeability. Furthermore, a production prediction model is introduced accounting for a non-uniform hydraulic fracture conductivity distribution. The results reveal that increasing the fracture conductivity leads to a rapid daily production increase in the early stages. However, above 0.50 D·cm, a further increase in the fracture conductivity has a limited effect on More >

    Abstract During the implementation of CO2 fracturing for oil and gas development, the force transfer effect caused by the unsteady flow of high-pressure CO2 fluid can lead to forced vibration of the tubing and ensuing structural fatigue. In this study, a forced vibration analysis of tubing under CO2 fracturing conditions is carried out by taking into account the fluid-structure coupling and related interaction forces by means of the method of characteristics (MOC). The results show that for every 1 m3/min increase in pumping displacement, the fluid flow rate increases up to 3.67 m/s. The flow pressure in the… More >

    Xingbin Zhao, Neng Yang, Hao Liang, Mingqiang Wei, Benteng Ma, Dongling Qiu
    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.11, pp. 2523-2540, 2024, DOI:10.32604/fdmp.2024.052766
    (This article belongs to the Special Issue: Fluid and Thermal Dynamics in the Development of Unconventional Resources II)
    Abstract The transient flow testing of ultra-deepwater gas wells is greatly impacted by the low temperatures of seawater encountered over extended distances. This leads to a redistribution of temperature within the wellbore, which in turn influences the flow behavior. To accurately predict such a temperature distribution, in this study a comprehensive model of the flowing temperature and pressure fields is developed. This model is based on principles of fluid mechanics, heat transfer, mass conservation, and energy conservation and relies on the Runge-Kutta method for accurate integration in time of the resulting equations. The analysis includes the… More >

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.10, pp. 2281-2300, 2024, DOI:10.32604/fdmp.2024.051594

    Abstract Continental shale oil reservoirs, characterized by numerous bedding planes and micro-nano scale pores, feature significantly higher stress sensitivity compared to other types of reservoirs. However, research on suitable stress sensitivity characterization models is still limited. In this study, three commonly used stress sensitivity models for shale oil reservoirs were considered, and experiments on representative core samples were conducted. By fitting and comparing the data, the “exponential model” was identified as a characterization model that accurately represents stress sensitivity in continental shale oil reservoirs. To validate the accuracy of the model, a two-phase seepage mathematical model More >

    (This article belongs to the Special Issue: Fluid and Thermal Dynamics in the Development of Unconventional Resources II)
    Abstract Horizontal well drilling and multi-stage hydraulic fracturing technologies are at the root of commercial shale gas development and exploitation. During these processes, typically, a large amount of working fluid enters the formation, resulting in widespread water-rock interaction. Deeply understanding such effects is required to optimize the production system. In this study, the mechanisms of water-rock interaction and the associated responses of shale fabric are systematically reviewed for working fluids such as neutral fluids, acid fluids, alkali fluids and oxidative fluids. It is shown that shale is generally rich in water-sensitive components such as clay minerals,… More >
