Current Status and Advances in 2D, 3D and 4D Gravity Exploration
Gravity provides density distribution as petrophysical parameter constraining seismic velocity. Currently we can select traditional land survey performed with up-to-date digital gravimeters with GPS. A small crew can carry out large survey with high resolution, as current instruments increased resolution by one order during the latest decades. Very efficient is a pre-seismic survey that may improve line planning. Large range of traditional and new processing techniques are applied to enhance the useful signals and display them in simple 2D, or shaded, or similar form. Using new software packages, specialized in-house, or industrial leaders, may then transform the data into 3D cubes and other 3D space imaging, preferably in conjunction with seismic models in order to mutually constrain the results.
