Successful Annulus Zonal Isolation Packer installation
Saltel Annular Zonal Isolation Packer installation in Venezuela has been a success. The client needed to isolate two producing zones with shale between, in the Boscàn field. They realized most of the water produced and fine migrations were generated from the upper Boscan and the shale zone.
The open hole annular packer, a 51-2in AZIP-C 0-1 has been set below the shale to isolate the upper section and produce from the lower Boscàn only to increase the production and reverse the decline of the field production.
The Annular Zonal Isolation Packer was 8in OD, it has been run through a 9.625in 47ppf casing and successfully installed in a 10in underreamed section at 9,599 ft depth using a straddle setting tool as part of a standalone completion including Quantum packer and Facsrite sand control screens.
