The fracture initiation process and the wellbore hydraulics are not simulated in this work. A schematic of the multiple transverse fractures from a horizontal well is shown in Fig. 6. For the sake of rapid analysis, the small scale simulation examples are presented in this paper. The numerical...
This methodology makes the connection between the reservoir scale geomechanics with wellbore scale geomechanics. With it, a wellbore stability analysis for infill wells through a coupled geomechanics and reservoir simulator is developed. Fig. 1 shows that the production and injection operations of parent...
Full size table Subsurface sensing system Preliminary advancements have been made in external optical fiber cable technology and data collection equipment. However, monitoring strain response in weakly coupled optical fibers within the wellbore remains challenging. There is a pressing need to develop softwa...
A reservoir simulator first estimates rock displacement parameters (u, v, and w) representing rock movement in the x, y, and z directions. When the rock displacement parameters (u, v, w) are determined, “εx,y,z” (the ‘x,y,z elongation strains’) and “γxy,yz,zx” (the ‘she...
[52] simulated 2D propagation of hydraulic fracture in a natural fracture network mapped from realistic outcrop at field. However, the construction of field-scale subsurface natural fracture network faces complex uncertainties since the relevant information provided by wellbore logs are limited. The ...

have developed HOLA, a steady-state simulator for geothermal wells [1]. Tian et al. have developed a geothermal wellbore model based on the two-phase flow conservation equations. This model is used to simulate the multiphase flow inside the wellbore and the heat transfer process between the ...
Imbibition occurs in a multiscale flow space, primarily within the matrix, flowing through bedding planes to fractures and the wellbore. Jiang Tingxue et al. suggested that fractures enhance imbibition effects, a viewpoint validated by Yang Zhengming et al. through comparative studies between ...
Full size|PPT slide Fig. 12shows the changes of pressure and water saturation during the simulated well soaking process. It can be seen that after the well stops injection, the fracturing fluid near the wellbore diffuses around, and the pressure in the hydraulic fracture continues to decrease,...
