We perform hydrodynamic survey using the tool PLT-9.2 which is aimed to solve the following tasks:

- definition of the fluid movement profile;

- monitor net pay zone, annular fluid migration, well casing integrity, hydrodynamic reservoir characteristics;

- definition of the current coefficient of gas and oil saturation;

- definition of current flowrate (spinner flowmeter);

- estimation of current reservoir saturation (dual-spacing neutron extension tool).

PLT-9.2 records the following parameters:

- temperature;

- pressure;

- thermoconductive flowmeter;

- water content;

- resistivity;

- noise;

- mechanical flowmeter (spinner);

- casing collar locator;

- gamma ray;

- dual-spacing neutron tool (can be used as an extension of the tool).
