Nowadays LLC "Gazprom geofizika" applies the following technologies for well surveying and development in the cased borehole:
– deep pressure drawdown with the use of ejector device UEGIS;
– swabbing;
– compression.
All the approved technologies were implemented together with maximum possible collection of geophysical information for the purpose of process monitoring as well as for analysis of site condition before and after formation treatment process.
After putting into service of the promising method for creating deep drawdown by ejector device UEGIS, LLC «Gazprom geofizika» could offer the advanced capabilities to its customers:
– to adjust a value of reservoir drawdown and stimulate inflow from it;
– to treat the formations with portable instruments under the preset drawdown conditions;
– to carry out acid treatment under dynamic conditions;
– to carry out geophysical studies at the specified drawdown values on a real time basis and obtain the maximum amount of geophysical data.
