Abstract
A completion assembly for subterranean use from a surface in multiple zones that are gravel packed together has a plurality of screens spaced apart with tubulars that define an annulus around them in the subterranean location for receipt of gravel in the annulus. The annulus spans multiple zones and the annulus is isolated from the surface by at least one packer. At least one barrier forming chemical is delivered from the tubulars into the annulus that has been gravel packed. The barrier chemical forms a barrier with the gravel in the annulus between at least two zones. The tubulars comprise at least one opening located between zones. A straddle tool is insertable from the surface into said tubulars to isolate the opening for chemical delivery into the annulus.
