to select the optimal and environmentally friendly technology for the development of oil and gas fields, it is necessary to assess in advance the likely deformation processes of the earth's surface. To this end, it is recommended to build predictive geodynamic models before the start of field development, taking into account the geological characteristics and tectonic activity of the area under consideration, as well as the specific features of the reservoir. Research methods. In this paper, two models of subsidence of the earth's surface in a hydrocarbon field are considered: a parametric spatial model developed at Delft University of Technology and a model based on the Knoté influence function developed at the Canadian Center for Geodetic Engineering. The first method is more suitable for describing a smooth and gradual subsidence in deep gas reservoirs and allows you to assess the spatial-temporal pattern of movement of the earth's surface. In the second method, geodynamic processes are modeled based on the functional relationship between reservoir compaction and subsidence of the day surface, taking into account the location of the oil reservoir, physical and mechanical properties of rocks, changes in reservoir pressure and the results of surface deformation monitoring and is recommended for oil fields. Research results. A comparative analysis of these methods is carried out on the example of the Tengiz oil and gas field in Western Kazakhstan. An assessment of the accuracy of building a model is carried out by comparing the calculated values of soil subsidence with the data of radar interferometry, and estimates obtained by other researchers. Recommendations are given on the application of the considered methods in the construction of predictive models of oil and gas fields, the necessity of calculating the transfer coefficient of the reservoir compaction to the position of the day surface, taking into account the depth of the reservoir and the physical and mechanical properties of the rock massif, is indicated.
