COMB-AT technology
COMB-AT technology
Purpose:
COMB-АТ is designed to improve communication between the wellbore and the formation in oil and gas wells. Enhancing fracture initiation and connectivity with the formation leads to increased oil and gas production and/or well intake capacity.
Plug&Perf technology is not just another hydraulic fracturing method. This is a demonstration of the technological sovereignty and operational superiority that we have achieved.
| Characteristic | COMB-АТ technology |
|---|---|
| Max temperature, °C | 150 |
| Max allowable operating hydrostatic pressure, MPa | 80/103,5* |
| Explosive mass, kg | 13,5 |
| Specific gas generation volume, min, l/kg | 700 |
| Explosive combustion temperature, °C | 3200 |
| Shot density, shots/m | 20 |
Advantages:
- COMB-AT enables perforation and inflow stimulation in the well to be performed in a single operation;
- the use of COMB-AT combined with the PerfoLab simulation software represents a comprehensive approach to ensuring efficient and cost-effective well stimulation;
- the COMB-AT perforation system can be used for completing new wells, remedial perforation for inflow, waterflood/injection wells, as well as in perforation operations prior to hydraulic fracturing.
Operating principle:
To initiate and propagate fractures in the surrounding reservoir rock, COMB-AT uses a specialized energetic solid propellant material that ignites after the detonation of the shaped charge, generating a high-energy pressure pulse. The result of this process is perforation channels with enhanced effectiveness.
