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.
- 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.
