“…Successively, the vertical fluid velocity due to buoyancy in the reservoir is significantly lower than that of the horizontal velocity, and therefore, the no‐flow boundary condition can be fairly assumed for the top and bottom faces of the reservoir as well (Jackson et al . ).…”

Evaluation of recoverable energy potential from enhanced geothermal systems: a sensitivity analysis in a poro‐thermo‐elastic framework

This study presents application of an efficient approach to simulate fluid flow and heat transfer in naturally fractured geothermal reservoirs. Fluid flow is simulated by combining single continuum and discrete fracture approaches. The local thermal nonequilibrium approach is used to simulate heat transfer by conduction in the rock matrix and convection (including conduction) in the fluid. Fluid flow and heat transfer models are integrated within a coupled poro-thermo-elastic framework. The developed model is used to evaluate the long-term response of a geothermal reservoir with specific boundary conditions and injection/production schedule. A comparative study and a sensitivity analysis are carried out to evaluate the capability of the integrated approach and understand the degree by which different reservoir parameters affect thermal depletion of Soultz geothermal reservoir, respectively. Also observed, there exists an optimum fracture permeability after which the reservoir stimulation does not change the recovery factor significantly. Estimation of fluid temperature by the assumption of local thermal nonequilibrium heat transfer between the fracture fluid and the rock matrix gives fluid temperature of about 3°C less than that of estimated by thermal equilibrium heat transfer at early stage of hot water production.

“…Accurate models are needed to study and investigate this pressure drop. Jackson et al (Jackson et al 2011) examined a new approximation model by using computational fluid dynamics, which was developed for the pressure drop in horizontal wells. A real horizontal well and the modeled boxed section are presented in Fig.…”

“…Finally, it was concluded that a significant pressure reduction (over 10%) happened in efficiency at early periods, i.e., 10 days, in homogeneous reservoirs. Also, with the passage of time, the reduction in oil recovery factor became slower, and the axial pressure drop was more in heterogeneous reservoirs than that in homogeneous reservoirs (Jackson et al 2011).…”

Application of CFD technique to simulate enhanced oil recovery processes: current status and future opportunities

Nowadays, because of the reduction in oil resources and the passage of the first and second life period of current reservoirs, using enhanced oil recovery (EOR) methods is of great importance. In recent years, due to the developments in technology and the advent of powerful computers, using simulation methods in enhanced oil recovery processes is on the rise. The computational fluid dynamics (CFD) method, as a branch of fluid mechanics, is a suitable method for studying and simulating EOR methods. In this study, a review was done on the application of CFD studies for simulating EOR methods. Also, potentials for future studies and the challenges researchers may face in this method were mentioned. Although using this method in enhanced oil recovery processes has recently started, different areas for more studies still exist. To optimize the usage of this method in future studies, the necessity of multiphase models and solution methods development, as well as considering all microscopic parameters such as interfacial tension and viscosity in investigating oil recovery factor is of great importance.

“…Dikken [1] in 1989 proposed the first model to evaluate the production performance of a horizontal well with the consideration of the wellbore pressure drop. Since then, [2,3] active research work has been carried out on horizontal wellbore pressure drop using experimental [4][5][6][7][8], analytical [9][10][11][12], and simulation methodologies. Asheim et al [7] made a study on friction factor correlation for horizontal wellbore, which included accelerational pressure drop caused by the continuous fluid inflow along the wellbore.…”

The Pressure Drop Model of Liquid Flow with Wall Mass Transfer in Horizontal Wellbore with Perforated Completion

The fluids in horizontal wells can exhibit complicated flow behaviors with wall mass transfer, partly due to the interaction between the main flow and the radial influx along the wellbore and the completion parameters used. This paper presents a novel regression model established based on the experiment data retrieved from the available literatures to determine the apparent friction factor for a single phase wellbore flow. The proposed model has the potential to be readily applicable to different perforation parameters, such as shot phasing and shot density. Compared with other models in the same practical example which is offered by Ouyang et al., the model of this paper to calculate the wellbore pressure is applicable and reasonable. This new model can be easily incorporated into reservoir simulators or analytical reservoir and horizontal wellbore inflow coupling models.
