Project's objective

  1. Observations at the geodynamic range of license areas (LA) of oil and gas fields using the Earth remote sensing method. Carrying out a full cycle of radar interferometry at a geodynamic test site in accordance with the Project of engineering-geological substantiation of the need to create a geodynamic test site at the Customer's license area.

  2. Study of the displacement of the earth's surface during field development in accordance with the Project for the formation of a geodynamic test site and a system for observing deformations of structures in the license areas:

    • a comprehensive assessment of the state of the earth's surface for subsidence / uplift;

    • identification of subsidence zones in the areas of the field not covered by the linear observation station;

    • detailed analysis of observation results, identification of the cause of deformations;

    • use of observation results in developments related to the production of hydrocarbons at the field.

Completed work

  1. Development and coordination of the work program with the Customer.
  2. Radar sensing of the geodynamic test site from TerraSAR-X satellites (X-band spacecraft), the minimum re-passage interval is 11 days, the number of filming is 27 scenes.
  3. Determination of deformations of the geodynamic test site by the method of radar interferometry, comparison and assessment of accuracy with the sounding data of 2014-2018.
  4. Obtaining maps of vertical and horizontal (west-east) displacements of the earth's surface and structures.
  5. Based on the results of a series of radar interferometry, an analysis of the obtained values ​​of the deformations of the earth's surface, buildings and structures with predicted geomechanical development parameters, real parameters of reservoir pressure drop and oil withdrawals, and data from hydrodynamic modeling of field development was performed. A general analysis of the results of radar interferometry was carried out, recommendations and methods for the application of new observation methods were prepared.
