Project “PEV – Online”, Irkutsk region

More than 30 highly qualified employees
8 fchemical field laboratories
101 test sites
26 wells
Verkhnechonskoye oil and gas condensate field



The Pressure Equalizing Valve (PEV) recording when operating on a jet pump is performed by a self-contained thermomanometer installed in the jet pump insert. The quality of the PEV recording is evaluated after removing the insert with the gauge.


A new “PEV – Online” insert was developed, allowing a complex geophysical instrument to be lowered to the bottomhole for more accurate timing and recording quality.


Reduction of time costs for recording PEV, possibility to adjust the duration of the study in real time (increasing/reducing the recording).
