METHOD OF ICE COMBINED MONITORING IN WATER AREA OF HYDROCARBON DEPOSIT AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2025 - IPC G01V11/00 G01V7/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to means of ice combined monitoring in the water area of a hydrocarbon deposit. Complex of ice combined monitoring consists of data acquisition and processing device connected to network of observation points. At that, the observation points network includes located on the mainland long-term reference gravimetric measurement points, located on the deposit water area ice surface temporary gravimetric measurement points, and temporary combined monitoring points (TCMP) on which metal platforms with gravimeters are installed, as well as located on the mainland long-term basic geodetic observation points. Each TCMP represents a shaft of a drilling string drilled to the bottom of the water area of the deposit with satellite antennas mounted on it, tacheometric reflectors, inclination equipment, a tight lowering complex located at the bottom of the water area of the deposit. Tight dropping complex is made in the form of four tight dropping containers with remotely controlled movable platforms for attachment and alignment of relative gravity meters, remotely controlled gravimeters and high-precision water pressure sensors.

EFFECT: high accuracy of monitoring results.
