|1 hour lecture + 30 minutes Q&A|
|Free for EAGE members|
|Computer with Internet connection and audio/video capabilities|
EAGE webinars are live presentations with lecturers selected from the best presentations at EAGE Conferences. After the lecture, participants can interact with the instructor and ask questions. Joining a webinar is simple: all you need is a computer with Internet connection and audio/video capabilities (no software installation required). This service is complimentary for EAGE members and places are limited.
Coincident gravity anomalies and seismic base salt closures were observed in this locality. The gravity anomalies are larger in amplitude and not equivalent to any possible post-salt structure, independent of density. In short, the scenario 3D gravity modelling suggests that these are indeed sub-salt structures, most likely localized basement or some other high density closures - which is consistent with the seismic imaging.
Additional modelling of the various velocity cubes used for sub-salt seismic imaging in 3D using gravity have been used to globally select the ‘best’ velocity model to better constrain deep seismic imaging. Note that one of these targets has since been drilled, intersecting gas/condensate in sandstone reservoirs validating the sub-salt interpretation and the petroleum system in this area.
Additional sub-salt structures identified using this methodology are currently being evaluated by new seismic, gravity and magnetic acquisition.
