Abstract
In 2018 an operator efficiently acquired a Salt Proximity Survey while drilling a development well. The objective of the salt proximity survey was to help delineate the extent of the reservoir by mapping the intersecting salt flank with increased accuracy over the surface seismic image.
The salt proximity survey in this well successfully proved the concept for conducting such a survey using Seismic While Drilling LWD technology with both a rig source and an offset vessel source. The final result from the salt proximity survey data processing proved to be valuable for the operator and partners by improving the reservoir model, firming up reserve estimates, and optimizing well placement for future wells in the development.
