Abstract This paper outlines implementation results of pilot polymer flooding project in the South Turgay basin's field in Kazakhstan. During pilot injection, production data and main parameters were gathered and analyzed. In the paper contains description of general information about selection of the appropriate reservoir area, including geology, water quality and other main parameters for the best polymer selection. Based on screening of these parameters an area was selected for pilot polymer flooding implementation. Polymer flooding carried out using two injection wells. After continuous injection, according to injection protocol, initial watercut decreased in the oil production of producing wells due to improvement in the reservoir sweep efficiency caused by flooding. Bottomhole pressures and injection rates in the injection wells varied insignificantly. Oil production increased comparing with the standard water flooding process that was applied initially. Oil production was monitored and analyzed by Operator Company since the begging of the injection. Production history from the beginning of pilot polymer flooding project demonstrates efficiency of this EOR method. Considering positive results of this injection stage Operating Company plans to continue polymer solution injection in the next stages of the field developmet.
