Formation Drill Stem Testing (DST)

Water bore Drill Stem Testing (DST) is a method of selectively surveying isolated portions of a bore after it has been drilled.

By performing water quality and yield tests over discrete intervals in the bore, one can determine how best to proceed with the design of the screened intervals. This allows the exclusion of production from aquifers of poor water quality and maximum utilisation from those which exhibit a high quality.

AGE manufactures and supplies a broad range of open and cased-hole straddle packer assemblies and associated equipment for use in such DST operations. This can include both the DST equipment itself and either airlift or electric submersible pumping equipment if required.
