Abstract. We discuss results of measurements developed by gravity method and space geodesy method at territory of Zapolyarnoye gas-oil deposit and Yamburgskoe gas-oil deposit situated at Polar part of West Siberia in sub-arctic zone of Yamal-Nenetskii autonomous region. Mineral deposits exploitation and lot of pipelines need the control of current motion of earth surface. Research of displacement and other phenomenon were developed by of space geodesy and absolute gravity methods. Now we can receive kinematic parameters (rates of subsidence and horizontal motion) and addition information reflected of fluid motion into deposit layers. The land displacements rates at different short epochs registered at large man-made objects are shown. Rates for hydro-object estimated at 5 mm/y level. Gravity and space geodesy results deceived at Zapolyarnoye deposit area at North part of West Siberia were analysis. There was estimated subsidence rates 21–23 mm/y. Gravity increase registered up to 7 microGal at deposits exploitation area (epochs 2006–2008 yy.). In this case gravity increasing connected with surface subsidence (with normal vertical gradient). We estimated subsidence rates 16–21 mm/y at Yamburgskoe gas-oil deposit. This result agreed with Zapolyarnoye rates. Horizontal rates and it’s orientation differed at different deposits.
