Permanent downhole monitoring gages (PDMG) are significantly improving. Gages reliability and accuracy are increasing. At the same time there are still many in Russia believe that the organization of continuous monitoring - is branding costs that do not bring profits.
The paper presents an example of one of the Western Siberia fields, where the effect of PDMG wide implementation is easy to see. Based on the analysis results of the monitoring of downhole parameters using PDMG, which are installed in all the wells in 2012, large-scale optimization of production enhancement operations have been done to improve oil recovery to 0.09 relative percent.
The subject field in Western Siberia is terrigenous and has complex geology. This is due to layers pinch-out, complex deposits configuration and significant lateral heterogeneity. Reservoir depth is more than 2.5 km. In all wells hydraulic fracturing operation has been performed (fracturing).
