... are simultaneously simulated at the horizontal and deviated well locations. The velocities honor the "hard" velocity information from the vertical wellbores, the top depths from the deviated wells, and the "less than" depths imposed by the horizontal well data. It can also honor secondary information...

... Abstract A major challenge in well planning and in 3D reservoir modelling is to incorporate seismic information. In a North Sea setting, the wells constitute only a few pinpricks in the reservoir, while the seismic data are acquired in 3D over the whole field. Thus seismic data constitutes...

... and obtain quantitative information on projected formation dip, as well as distance of the bit from formation boundaries and faults. Both the computational framework and graphical rendering are 3-D. The continuous updating of these models maximizes the utilization of LWD data and prior models to support real...
