HYDRAULIC FRACTURING

Hydraulic packer for hydraulic fracturing PGRP

Hydraulic Packer PGRP is applied for open wellbore (or casing string) zonal isolation during
different technological operations performance, including multistage hydraulic fracturing
(MSHF).
The packer operates as follows:
• after liner running into the adjusted depth and flushing, a controlling ball is dropped till
its setting into a valve KO seat, after which the pressure starts to increase.
• for packer hydraulic drive unit actuation the overpressure 16 (33) MPa is created in
liner pipes. When the adjusted pressure is achieved, shear bolts are cut off and the
packer is actuated.
For packer operation at significant pressures it is recommended to install the packer in
intervals with open bore nominal diameter.
