Drillable cement retainer (bridge plug) PRZ

• Isolation of formations, including in horizontal parts of well
• Protection and saving producing reservoir property
• Bi-directional differential pressure
• Average time to drill out by milling tools is 1:30 hours

Hydraulic packer P-YADZH-G

• Packer setting is carried out by hydraulic pressure, unsetting is carried out by pulling up of tubing;
• Installation in horizontal and inclined sections of the borehole without depth restrictions;
• Maximum differential pressure up to 10000 PSI;
• Carrying out of formation hydraulic fracturing and operating well by system «2 in 1»
• Installing valve is in complete with shear seat of valve

1PROK-GRPB-2 Single Packer BHA for Massive Hydraulic Fracturing

This BHA is used for hydraulic fracturing including massive hydraulic fracturing in production strings with tubing of nominal outside diameter of 140 mm (5 1/2 inches) to 178 mm (7 inches) with pressure differential up to 100 MPa (15000 psi).

BHA APPLICATION ALLOWS

• to carry out hydraulic fracturing with probability of complications reduced to minimum both during BHA round-trip and during the operation itself.

ADVANTAGES

• possibility of massive hydraulic fracturing;
• downhole equipment BHA is set into a well by axial movements;
• attachments: equalizing valve, safety assemblies enable easy packer releasing and enhance the safety of remedial and emergency operations;
• enables to carry out several hydraulic fracturing cycles without tripping the BHA out.

Assembly for isolation of leakage with 2PROK-SIAG

• Isolate the leakage interval of the production casing in one descent;
• Eliminate multiple expensive repair and isolating works of casing;
• To change the downhole pumping equipment without lifting the packer assembly;
• Reduce the time of turning the well into production;
• Reducing repair and insulation works costs up to 20.100$ USD.
