Reviewed studies on the oil fields, calculated the volume of crude oil performed and the volume of injected water produced to maintain reservoir pressure. These data were compared with the results of repeated leveling measurements. Numerous repetitive instrumental geodetic measurements in the oil fields in different regions have shown that the area where the oil is extractedisnot bearing recent vertical crustal movements manmade. On the basis of numerous repeated leveling measurements in a seismically active region established pattern of recent vertical crustal movements during the catastrophic earthquake.
