Key words: well completion, reservoir properties, wall packing screen, pay zone, shock-wave stimulation.
The paper considers the method for preventing skin damage and improving zonal isolation quality when completing wells in harsh geologic environment. The method is realized at the completion stage before production casing string is run and involves controlled wall packing with PAA clay suspension and shock-wave stimulation with the following restoration of reservoir properties in the near-wellbore formation. Results of the analysis of the improved completion technology are presented; conclusions and practical recommendations are given.
