... ties and reliable depth conversion are also required for a better picture. A velocity model is necessary to obtain a depth image of the earth subsurface. It is developed here integrating all the available geological and velocity information from well and seismic data. The generated velocity model has...

... ABSTRACT The linear velocity model is often used for depth conversion of interpreted seismic horizons and for building preliminary velocity models for depth migration. The model has an implicit assumption that sediments are currently at their deepest point of burial, which may not be the case...

... across the hinge line, from the water bottom (7 msec) to bedrock (46 msec). The frequency content, signal/noise ratio and penetration were all significantly improved from the 2004 to the 2006 data. Geophysical Interpretation The seismic interpretation and depth conversion were performed using...

... time and depth, and avoids some pitfalls associated with interval velocity modeling. In many cases, an average velocity model can easily be built and with sufficient detail to meet the velocity accuracy required for successful time to depth conversion. Multiple velocity models built using different...

... and their associated uncertainty into a 3-D stochastic model of slowness. We restrict ourselves to situations where the geology is laterally smooth and most uncertainty lies in the depth conversion. This allows us to avoid expensive re-migration for multiple slowness models and concentrate on uncertainty in depth...

... Summary This paper focuses on the depth conversion of regional time maps offshore South-East Brazil, it also outlines the remaining hydrocarbon potential of deepwater exploration. The basis for this time and depth mapping is the interpretation of modern seismic data from the 225,000 line km...

... ABSTRACT In any exploration or field development interpretation project the starting requirements are a good image, good well ties and reliable depth conversion. In this paper we present the results of matching a prestack depth image to the well depths. Blocks K10 and K13 lie...

... on real data in an exploration setting. Introduction An interpreter working with time migrated data typically spends days or weeks building a velocity model based on time-depth tables and/or seismic velocity picks. Very rarely does vertical depth conversion of seismic data and interpreted horizons...
