“…For validation of the hoop stress value, obtained from numerical models, the following equation, based on the Kirsch and Mirabbasi analytical models, is selected for hoop stress calculation at the wellbore wall. This equation is valid before inducing the artificial fractures [15,35].…”

“…Therefore, fewer induced fractures are created, which, in turn, leads to less possibility of lost circulation. A higher fracture gradient guarantee a wider mud weight window, which can contribute to better drilling and completion practices, and, in the best case, it can lead to a reduced number of casing strings [2,[13][14][15][16][17].…”

“…They concluded that after WBS the compressive hoop stress and confining stress are altered [29]. Mirabbasi et al (2020) developed a thermo-poro-elastic analytical model to study the effects of different well geometrical and rock mechanical properties on WBS effectiveness. The authors also presented the stress intensity factor (SIF) as the stress concentration at the fracture tip to evaluate the WBS operation.…”

“…The authors also presented the stress intensity factor (SIF) as the stress concentration at the fracture tip to evaluate the WBS operation. Comparing the results of elastic, poro-elastic, and thermo-poro-elastic models, they showed the more accurate results of the thermo-poroelastic model, as the variation of temperature and pore pressure significantly affects the state of stresses in near-wellbore region [15].…”

Lost circulation is considered a time-consuming, costly problem during the construction of oil and gas wells. There are several preventive techniques to mitigate this problem. Stress cage technology is a mechanical lost circulation method, in which the formation at the wellbore wall is strengthened to stop the creation of induced fractures as one of the main causes of lost circulation. In this research, a two-dimensional numerical model, considering the elastic, poro-elastic, and thermo-poro-elastic behavior of the rock, is built to investigate the effectiveness of the stress cage method. Results show that better performance of the technology is achieved if the fractures are bridged close to their apertures. Additionally, it was found that the difference between the elastic, poro-elastic, and thermo-poro-elastic models is slightly visible. The conclusion states that the application of the stress cage methods leads to an increase in hoop stress and subsequent formation fracture gradient.

“…The prediction of wellbore temperature and pressure field has always been a major problem of common concern to scientists (Mirabbasi et al 2020), because it is related to the accurate construction of oil production technology (Li et al 2020;Jung et al 2020), the safety of pipe string (Guo et al 2021;Li et al 2021;Wang et al 2019a), the normal use of various downhole tools (Wang Sifan, Zhang Ankang, Hu Dongfeng 2021), the reliability of production process (Wang et al 2019b), and the wax and scale prevention of oil and gas wells affected by temperature and pressure (Wei et al 2017;Dalong et al 2021;Yang et al 2021;Wang 2019). Nowadays, in the daily production process of gas wells, the phase change of natural gas in the wellbore is becoming more and more common (Gholamzadeh et al 2020;).…”

With the development of gas well exploitation, the calculation of wellbore with single-phase state affected by single factor cannot meet the actual needs of engineering. We need to consider the simulation calculation of complex wellbore environment under the coupling of multiphase and multiple factors, so as to better serve the petroleum industry. In view of the problem that the commonly used temperature and pressure model can only be used for single-phase state under complex well conditions, and the error is large. Combined with the wellbore heat transfer mechanism and the calculation method of pipe flow pressure drop gradient, this study analyzes the shortcomings of Ramey model and Hassan & Kabir model through transient analysis. Based on the equations of mass conservation, momentum conservation and energy conservation, and considering the interaction between fluid physical parameters and temperature and pressure, the wellbore pressure coupling model of water-bearing gas well is established, and the Newton Raphael iterative method is used for MATLAB programming. On this basis, the relationship between tubing diameter, gas production, gas–water ratio, and wellbore temperature field and pressure field in high water-bearing gas wells is discussed. The results show that the wellbore temperature pressure coupling model of high water-bearing gas well considering the coupling of gas–liquid two-phase flow wellbore temperature pressure field has higher accuracy than Ramey model and Hassan & Kabir model, and the minimum coefficients of variation of each model are 0.022, 0.037 and 0.042, respectively. Therefore, the model in this study is highly consistent with the field measured data. Therefore, the findings of this study are helpful to better calculate the wellbore temperature and pressure parameters under complex well conditions.
