Formation hydraulic
fracturing collar barracuda BUR-GRP-MV
Used for multi-interval formation hydraulic fracturing when performing completion operations in cemented horizontal and directional wells.
If it is necessary to remove key sleeves, service tool is lowered. Up to 20 key sleeves may be removed in a single run.
If it is necessary to remove key sleeves, service tool is lowered. Up to 20 key sleeves may be removed in a single run.
Maximum number of stages is 100.
Collar is opened by release and pumping of key sleeve with soluble allot ball.
Provides possibility of liner rotation as well as formation hydraulic fracturing collars cementing.
Drilling out is not required.
Simple adjustment of circulation ports opening pressure using shear bolts.
Circulation ports may be closed to cap watered interval or perform repeated formation hydraulic fracturing.

SPECIFICATIONS
In order to perform multi-stage formation hydraulic
fracturing operations without pumping stoppage
(without overflushing excessive liquid volume to
formation), a system of key sleeves shooting to the
flow based on revolver cylinder principle may be
used.
Cylinder is installed on formation hydraulic fracturing
Christmas tree and controlled remotely to comply
with industrial safety regulations.
Gates are opened by hydraulic actuator.
Maximum key sleeves load in cylinder is 20 pcs.
Max working pressure is 70 Mpa.
