In the zone of hydrocarbon deposit location especially of gas and - condensate deposit is constantly present the gravitational anomaly conditirned by the difference of the trap mass filled with water mainly of high mineralization. Before starting up the gas deposit production the gravitational anomaly can be determined by comparing the mass of the gas compressed in the tran with the water mass which hay billed all the gas pochet of the deposit larlier. When sampling gas brom gas and gas - condensate deposits, that is, with mass-transfer of hadracarbons from deposits on to the surface, the gravitational anomaly increase, it is being known that this increase depends on the intensity of gas campling and decrease of the gassy seam. The detailed estimation of the gravitational anomaly, before starting up the production of the gigantic gascondensate deposit in Hass R’Mel (Algeria) and then the increase of the gravitational anomaly in the process of its production had been carried out in this work.
