Paper: Shallow Sucker Rod Wells Fluid Inertia

Fluid inertia forces can be large enough to be considered in sucker rod simulators. Fluid inertia forces are larger with shallow wells, large pumps, high stroke rates, and/or lower compressibilities. Texas A&M U has developed a fluid inertia model. This paper covers the primary assumptions, the equations, the boundary conditions, the initial conditions, a parameter study based on field data, the solution method, the discretized equations, the pump position, and the calculation sequence.
