Imaging deep geology using full tensor gravity gradiometry inversion: K-2, deepwater Gulf of Mexico

A common misunderstanding in the oil industry is that Full Tensor Gravity Gradient (FTG) data<br>is only of use when resolving shallow sections of the earth model. This paper will highlight the<br>ability of FTG to resolve deep as well as shallow geological targets by showing examples from<br>an imaging study of the pre-salt K-2 Field, Deep Water Gulf of Mexico. Combined Pre Stacked<br>Depth Migration (PreSDM) and gravity gradient inversion was used to resolve the base of salt at<br>a depth in excess of 7 ½ kms.
