Description
Technical characteristics

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.
