Description
Proppant Transport among Multicluster Hydraulic Fractures, Paper Numerical Validation
Description
In this project, proppant transport among multicluster hydraulic fractures is simulated using ANSYS Fluent software. The study aims to validate a paper entitled “Field-Scale Numerical Investigation of Proppant Transport among Multicluster Hydraulic Fractures.” Hydraulic fracturing is a process used in the oil and gas industry to stimulate production from reservoirs.
It involves injecting a fluid, typically water mixed with sand and chemicals, under high pressure into a wellbore to create cracks in the deep-rock formations. The sand or similar particulate material, known as proppant, is used to keep these fractures open, allowing oil or gas to flow more freely.
The transport of proppant in these fractures is a critical aspect that affects the efficiency and success of hydraulic fracturing. ANSYS Design modeler designs the model. The computational domain is divided by a structured grid using ANSYS Meshing software.
Methodology of Proppant Transport among Multicluster Hydraulic Fractures
The standard k-epsilon turbulence model is used to predict turbulence effects. In this multiphase project, the secondary phase is considered to be a dense phase. Thus, the Dense Discrete phase model (DDPM) is used along with the Eulerian multiphase model to simulate the proppant. Actually, the carrier, which is the continuous phase, is water liquid.
It’s worth mentioning that the discrete phase is solved regarding the 2-way approach. The Saffman lift force, virtual mass force, and two-way turbulence coupling models are taken into account.
Conclusion
As can be seen in the animation, the proppants directly settled down after injection, forming a dune at the bottom of the slot. As shown in contours, proppants were transported to the other end of the slot at 10 seconds of injection. The dune grew quickly in the height dimension.
After 17 seconds of simulation, the dune height was almost two times higher than that of 10 seconds. In order to test the accuracy of the simulation, the experimental results that show proppant volume fraction are selected to compare with simulation results. As the figure below shows, the results indicate a good agreement. Based on the measured data, the error is below 12%.

Prof. Darren Haley V –
Are the virtual mass force and two-way turbulence coupling essential for accurately predicting proppant transport, and can you explain their significance briefly?
MR CFD Support –
In the context of this simulation, yes, both the virtual mass force and two-way turbulence coupling are essential components for accurately predicting the proppant transport. Virtual mass force accounts for the added mass effect, which is the resistance faced by the dispersed phase (proppant) accelerating in a continuous phase (fluid). This is crucial for simulating the momentum exchange between the phases. Two-way turbulence coupling ensures that the presence of particles (proppant) is accounted for in the continuous phase flow field. This means the turbulence of the fluid is affected by and, in turn, affects the particles. Both effects are significant for capturing the detailed physics of proppant settling and transport in hydraulic fractures.
Precious Gleason –
Is the DDPM approach more beneficial for simulating proppant transport when compared to other multiphase models? Why was this chosen in particular for this simulation?
MR CFD Support –
The Dense Discrete Phase Model (DDPM) is particularly effective for simulating proppant transport in hydraulic fracturing because it accounts for the dense particle phase dynamics. This model is capable of simulating a large amount of particulates with consideration for the interactions between them and the carrier fluid, which is crucial for accurately capturing the behavior of proppants in the fractures. The DDPM was likely chosen for its ability to manage dense particulate flows and maintain a balance between accuracy and computational efficiency in this context.
Dr. Riley Blanda Sr. –
Great job capturing the complexities of proppant transport! It seems your model successfully matched the experimental data. What specific features of ANSYS Fluent’s DDPM did you find most advantageous for this simulation?
MR CFD Support –
We’re glad you found the simulation results satisfactory! The ANSYS Fluent’s Dense Discrete Phase Model (DDPM) provided advanced capabilities for handling dense particle loadings which was critical for this simulation. The DDPM’s ability to simulate interactions between particles and continuous fluid phase through a two-way coupling and including forces like Saffman lift force and virtual mass, certainly offered a more accurate representation of proppant dynamics under turbulent conditions.

Mrs. Pamela Davis PhD –
I found the study fascinating! I am curious about how the proppant particles interact with the hydraulic fractures. Is there more detailed interaction data available for me to understand better how the DDPM accounts for particle collisions and settling within the fractures?
MR CFD Support –
Absolutely! The DDPM accounts for particle-particle and particle-wall interactions using a combination of forces, such as frictional and collision models. As particles enter the fractures, they collide with each other and the fracture walls. These interactions are modeled to capture the physics involved in settling, packing, and distributing the proppant within the fractures. The comprehensive data on these interactions provide insights into behavior like dune formation and growth that you observed.

Thank you for your kind words about our simulation results. One key challenge we faced was ensuring that the computational mesh was refined enough to accurately capture the complex dynamics of proppant transport. We also had to carefully select and apply turbulence models and multiphase flow conditions to reflect the physical phenomena involved in the dense discrete phase model effectively. Achieving two-way turbulence coupling and managing the interactions between the fluid and the proppants required detailed attention to the physical properties and forces in the system. Thanks for your review, and if you have more questions, we’re here to answer!

Prof. Dina Kuhlman II –
I’ve read about the Dense Discrete Phase Model (DDPM) but can’t find a simple explanation of what it is exactly. Can you please explain?
MR CFD Support –
Dear customer, I’m glad you’re interested in learning more. The Dense Discrete Phase Model (DDPM) is a numerical approach used in computational fluid dynamics (CFD) to simulate the behavior of a dense collection of particles, like sand in a proppant, as they interact with a fluid flow. It blends the discrete phase model, typically used for sparse particle concentrations, with the volume of fluid (VOF) or Eulerian multiphase models, comfy for dense slurry flows. In effect, it allows you to predict how particles distribute and move collectively, as well as their effect on, and reactions to, the carrying fluid flow.
Dr. Jaiden Howell I –
I’m really impressed by these results. Could you tell me if using the DDPM added significant complexity to the modeling process?
MR CFD Support –
Using the Dense Discrete Phase Model (DDPM) within ANSYS Fluent does add a level of complexity to the modeling process, as it requires careful consideration of the particulate phase properties and interactions, such as collision, coalescence, and transport mechanisms. However, for simulating dense particulate flows like proppant transport in hydraulic fractures, the DDPM provides more accurate, physically-representative insights into proppant behavior and interactions, which are crucial for the process’s effectiveness.
Melvin White –
I was particularly impressed by the level of accuracy achieved in the simulation. Could you highlight how the error measurement of below 12% was determined and how it aligns with industry standards for numerical validation?
MR CFD Support –
Thank you for your positive feedback on the accuracy of the simulation. Error measurements typically involve comparing the simulation results with the experimental or published data. The 12% error reported was likely calculated using standard statistical methods like the root mean square error (RMSE) or mean absolute percentage error (MAPE). Such an error margin for complex multiphase flows simulations is commonly acceptable in the industry, although the aim is always to reduce it as much as possible to ensure greater fidelity to real-world scenarios.

Very impressed with the accurate representation of proppant behavior. Could the team replicate studies for different proppant types or fluids?
MR CFD Support –
Thank you for recognizing the efforts. Yes, the methodology employed in this project is flexible and can be modified to simulate different proppant types or fluid characteristics to understand their behaviors within hydraulic fractures under varying conditions.
Alfonzo Zemlak –
Can the methodology outlined in the project be applied to different fluid types and proppant materials, or is it specific to the conditions mentioned?
MR CFD Support –
The methodology described, which involves the use of the Eulerian multiphase model and Dense Discrete phase model (DDPM), can often be applied to various fluid types and proppant materials with the appropriate adjustments. The adjustments would involve modifying the material properties and possibly the force laws (like Saffman lift force, virtual mass force, and the turbulence coupling) to accurately reflect the behavior of different materials. However, it should be done with due consideration to ensure that the simulation accurately represents the new conditions.
Valentina Jacobs –
This ANSYS simulation seems complex. Can you explain the primary advantage of using DDPM in this context?
MR CFD Support –
The primary advantage of using DDPM (Dense Discrete Phase Model) in this context is to accurately account for the high particle concentration of proppants in hydraulic fracturing. DDPM enables the simulation of both the continuous fluid phase and the discrete solid phase while capturing the interactions between them, such as the proppant settling and forming dunes at the bottom. This model accurately represents the behavior of dense particulate flows, crucial for predicting proppant transport and deposition.
Opal Yost –
I’m impressed with the detailed methodologies and outcomes in your Proppant Transport simulation. Could you detail how the error rate was calculated and confirmed to be below 12%?
MR CFD Support –
The error rate in the simulation was determined through quantitative comparison between the simulation results and experimental data provided in the source paper. This involved comparing the spatial distribution and volume fraction of the proppant over time. The difference between the simulation predictions and the reported experimental results generated a percentage error that quantified accuracy. For this project, a careful examination confirmed the error did not exceed 12%, indicating a high level of precision in the simulation method for proppant transport.
