The objective of this work is to give insight into results obtained using a non-conventional sucker rod pumping in pumping wells of 2.7/8" in diameter. The principal characteristic of the system is the replacement of sucker rods by 1" maccarroni tubing, which reciprocate the pump plunger and direct the flow to the surface. The most important task was to calculate the appropiate pumping action as to have minimal risk to the well. The same is considered in the modification of the equipment of subsurface (sucker rod pump and maccarroni), polished rod and stuffing box UR - https://biblioteca.iapg.org.ar/ArchivosAdjuntos/LACPEC2001/Spe69550.pdf ER -
