Description

Foam drilling is a cutting-edge method used in the oil and gas industry, specifically for extracting non-Newtonian oil. This technique involves using foam-based drilling fluid, which has distinct advantages over traditional drilling muds. The foam’s low density and high viscosity are well-suited for navigating complex geological formations present in non-Newtonian oil reservoirs. By reducing the hydrostatic pressure on the wellbore, foam drilling minimizes formation damage and improves oil recovery rates. As the demand for unconventional oil resources continues to grow, foam drilling of non-Newtonian oil is set to be a vital component of future exploration and production strategies. These provocative reasons led us to simulate Foam Drilling of non-Newtonian oil.

Simulation Process

The designed form drilling geometry is demonstrated above in Figure 1. The complex twists in the model bring Fluent Meshing to the table. Despite the simplicity at first sight, 1498792 cells are produced to fill everywhere. As said, the non-Newtonian oil`s viscosity depends on shear stress acting on the fluid. This is the definition of non-newtonian fluid, though. Hershel-Buckly model tackles the problem.

 

Post-processing

The velocity contour analysis of foam drilling for non-Newtonian oil reveals interesting results in the flow dynamics within the wellbore. The contour displays a gradient of velocities ranging from 0.0 to 10.9 m/s^-1, with the highest velocities concentrated at the drill bit (indicated by the red area). This localized high-velocity zone is essential for efficiently cutting and removing formation material. The velocity gradually decreases along the wellbore as the transition from green to blue colors shows a controlled ascent of drilling fluid and cuttings. This velocity profile is characteristic of foam drilling, demonstrating its ability to maintain adequate lifting capacity while minimizing formation damage. The observed pressure drop of 21.14 psi further supports the effectiveness of foam as a drilling fluid, balancing between sufficient circulation and reduced wellbore stress.
