Which method uses symmetry by mirroring infinite solutions to solve linear boundary problems in reservoirs?

• A. Image Wells
• B. Flood Wells
• C. Mirror Wells
• D. Dual Wells

Answer: (A)

The idea being tested is using symmetry to satisfy boundary conditions by introducing mirrored sources. In linear reservoir flow, the pressure field from real wells combines with the fields from fictitious, mirrored wells. Placing an image well across a boundary creates a symmetric effect that enforces the boundary condition (such as no flow across that boundary). Repeating reflections yields an infinite array of wells, and the sum of all those contributions gives the correct solution in the bounded domain. This approach is known as image wells, because it relies on mirroring solutions to achieve the desired boundary behavior.
