TATNEFT Successfully Introduces Technology of Wells Operation with Application of Sucker Rod Pumps

This method of operating a well equipped with a sucker rod pump increases profitability of wells operation, including the ones in the fields at the late stage of development and those containing hard-to-recover reserves. Application of this method increases the current oil recovery and the crude oil recovery factor, which is explained by creating a zone of dilation (deconsolidation) of rocks around a wellbore in the interval of perforations where the sucker rod pump operates.
The technology is simple, fully adapted to field conditions and it is easily implemented in the process of routine remedial maintenance of wells. No constraints have been identified resulting from reservoir lithological properties, crude oil properties and reservoir pressure and temperature.
