Abstract
This study looks at the question of whether time-lapse gravity measurements could be used to monitor the density and geometry carbon dioxide plume in the ground for a typical Gippsland Basin reservoir. The considerations made indicate that gravity measurements would not be suitable as a means to detect carbon dioxide density, distribution and movement in a reservoir the size of the West Seahorse field. The maximum gravity anomaly that would be expected is calculated to be 1.4 -Gal, while the experience in other parts of the world, using sensitive sea floor gravity metres, indicate that at present this technology can resolve about 5 -Gal. Furthermore, the horizontal and vertical gradients of the maximum anomaly are of the order of 0.007 E ( 0.007 ?m/s2/km), while the most sensitive reported airship measurements of gravity gradient are reported to be resolving of the order of 1.7 E.
