Swelling Packer Type VNNP for Isolation and Multi-stage Fracturing

Swelling packer is designed for separation of strata, isolation of interstrata flows, multistage hydraulic fracturing and other types of work during well support and operation and is used:
for isolation of intervals in uncased wellbores;
to isolate the water inflow zone;
to ensure hermetic separation of intervals in horizontal wellbore.
Swelling and sealing is achieved by contact of the elastomer with the activating fluid.
