MONITORING DEFORMATION PROCESSES ON GROUND SURFACE AND AT CONSTRUCTION FACILITIES IN THE TERRITORY OF OIL FIELDS

The authors analyze deformation in the territory of oil production in the Caspian zone of the Republic of Kazakhstan. The deformation analysis includes integrated monitoring aimed at environmental protection and at safety of infrastructure, including construction of a search channel. The authors adhere to the integrated approach to the research, namely: generalization and analysis of the national and international experience of geodynamic studies; completion of repeated geodetic observation over deformation in the test areas using modern geodetic instrumentation; assessment of different influences on ground surface subsidence y means of theoretical calculation of reservoir roof subsidence; geodetic supervision of safe operation of such unique engineering structures as a sea channel. For efficient and safe recovery of oil, the natural and manmade impacts on development of deformation processes at reservoirs ae analyzed. This can enable control of such impacts on ground surface and engineering facilities. The prediction procedure is developed for ground surface subsidence by calculated values of reservoir roof subsidence using experimental data.
