The reasons leading to this increasing importance in the field development process will be reviewed. The main factors influencing the selection of the most important artificial lift techniques will be highlighted. The hydrocarbon fluid flows from the reservoir into the well, up the tubing the horizontal line and into the oil storage tank during this process the fluids pressure is reduced from the reservoir pressure to atmosphere pressure in a series of pressure loss processes, across the reservoir, across the completion (perforation / gravel pack – etc.), across the tubing and any restrictions, across the sub surface safety valve, across the surface choke, across flow line.Progressive cavity pump (PCP) is not new technology for the oil industry, it was invented by Rene Moineau in 1932 and became widely used as surface pumps, and in 1979 the first PCP was installed in sand production heavy oil wells in Canada. In particular the planning for this project to rerun PCP in EL-Shrara oil field in order to reduce the workover cost besides applying another artificial lift in the field even for the oil wells which have low flow rate. In this project three oil wells were applied for the study, software was running to get the results and comparing the results with actual production at the current artificial lift (ESP).Implementation of progressive cavity pump
