Paper presented at the SPE Middle East Artificial Lift Conference and Exhibition, November 28–29, 2018
Paper Number: SPE-192484-MS
... to extend the life of downhole equipment. For this study, we have installed a capillary string attached to the production tubing string and Sucker Rod pump. The capillary string has been successfully installed at pump seating depth (4,500 ft.). Chemical injection was commissioned at a rate of 5L/day...

... the above presented innovative simulation methodology, self-developed DDS were used. The DDS is working autonomously, is sealed data logger, which is used to measure the load within the sucker rod string, the motion in three directions and the temperature of the housing. The DDS can be installed with...
