Abstract
Summary
We present a case study on the Dukhan oil field, where we built a near surface velocity model using resistivity and gravity measurements. The objectives were for both static corrections and constructing a robust velocity model of the near-surface to be integrated with depth imaging processing (PSDM). Vertical electrical soundings provided a resistivity model with structural information that was used to constrain the density model. Through the Gardner and Faust equations, we built a near surface velocity model. Its introduction in PSDM had a visible impact on the deeper structure obtained from imaging, and resulted in a better fit between the seismic horizons in depth and information from the well.
