TRIAL EXPERIMENT OF DUAL ESP PRODUCTION TECHNOLOGIES APPLICATION FOR MULTI-RESERVOIR FIELDS OF LUKOILWEST SIBERIA

This work represents the results of dual production technologies introduction at Urayneftegaz oil fields which allowed, under the conditions of low permeable reservoirs, to:  increase the sweep and intensity of multi-reservoir field development by isolated development of certain layers;  ensure produced fluid accounting from each of the reservoirs;  efficiently manage the range of bottomhole pressures;  extend the field's economic development time  reduce operational costs
