The maximum accuracy of field gravity measurements is currently needed to solve the following geological tasks: gravimetric search for hydrocarbon deposits, karst detection, monitoring the development of gas fields, deposits of high-viscosity oils and natural bitumen, monitoring the underground gas storage facilities operation, monitoring geodynamic sites of nuclear power plants. Improving the accuracy of gravimetric surveying is possible in several ways: preliminary testing of gravimeters at a certified gravimetric range, additional thermal insulation of gravimeters, rational equipment of gravimetric points, gravimeters protection from atmospheric influences and vibrations during transportation, high-precision geodesy. When carrying out gravimetric monitoring, in addition, it is necessary to take into account changes in the relief in the near observation points zone and changes in soil density (for example, due to changes in humidity). The above technological methods have been tested in practice and improved over the past decade by the specialists of the "TNG-Kazangeophysica" LTD in the Far North and Eastern Siberia harsh conditions.
