... of modeled log responses along the planned well path considering the offset well information. Whereas 3D geocellular property modeling-while-drilling is comprised of two steps i.e., fine layering and gridding (FLG) followed by property simulation and regular model updates with new real-time log and well pick...

...) seismic surveys to look ahead for pore-pressure prediction, geostopping, and obtaining high-resolution seismic imaging below the well path. Three wireline VSP runs and one seismic-while-drilling run were made. The first-run rig-source VSP at the 13 3/8-in. section was used to obtain an initial velocity...

... et al. 2008). In general, the optimal location for a well in a thick reservoir is selected on the basis of future performance. The preferred well path is often defined with reference to geological boundaries, including overlaying conductive or resistive boundaries (such as shale, anhydrite, and oil...

... by this key requirement, new technologies continue to emerge to help geologists, drillers, and reservoir engineers geosteer the wells. In recent years, two types of LWD information have been used. Wellbore imaging on one hand recognizes when a well path has left the reservoir and determines the angle of exit...

Downscaling is applied to generate a fine resolution model along the planned well path. Using nearby welldata, the model is subsequently populated...
