Geodetic Measurements of Underground Gas Reservoirs

The size of expected deformations of underground gas reservoirs may be dependent on the volume of gas fullness. Accordingto the proportional gas volume in both of measured gas reservoirs, the technology of geodetic measurements was taken out. Spatialdisplacements were observed by the method of vertical line, with EDM and vertical movements of monitored points were measuredby precise levelling. Together with geodetic measurements, the geological survey was also realized.
