Deep reflection shear wave imaging (DSWI) overcomes this limitation by mappingacoustic reflections away from the borehole, even if they are not intersecting the wellbore.
通过对远离井眼的声波反射进行测绘，深反射横波成像(DSWI)打破了这一局限性。

Flow mapping analysis can also be done with the data to create a map of the acoustic activity and present it in a 2d image that will show the flow path in the well.
