.... The lower coefficient of friction resulting from the coating reduces the abrasion between the coupling and the tubing. In that way, the risk of tubing holes can be reduced. After a coating solution was implemented in selected problematic wells, the rod run life could in average been tripled with no failures...

... sections of the jet pump, namely the suction, inlet and outlet of the mixing chamber and the outlet of the diffuser. From this, the relationships between M, N & h and the performance of the jet pump were determined. multiphase pump diffuser Efficiency coefficient viscosity ratio hydraulic...
