Proper functioning of the sucker rod pumping installations is strongly influenced by the sucker rod column dynamics and can be appreciated, as is well known and widely applied in practice, by the allure of the surface dynagraph. The paper presents some results concerning the simulation of the sucker rod column dynamics obtained with a computer program developed by the authors. The simulation results are compared with experimental results obtained at two pumping installations. Then, the computer program is used to study the sucker rod column dynamics for another pumping regime at one of analyzed installations.
