3 FAQs about [Montebay rock drill nitrogen addition]

How much oxygen is in a nitrogen gas drilling system?

In systems containing natural gas and air only, the natural gas concentration needs to be between 5 and 15%, depending on pressure. Since air contains about 21% of oxygen while membrane-generated nitrogen contains less than 5% oxygen, it is uncommon to see a downhole fire/explosion in a nitrogen gas drilling operation. 4. Conclusions

How is nitrogen gas pumped into a well?

Preparation of nitrogen gas: The nitrogen generator is started first. The generated nitrogen gas is injected into the well by the compressors. Drilling operation is initiated when the gas pressure and gas flow rate reach the desired levels for the well condition.

Does nitrogen fracturing produce micro-cracks?

In nitrogen fracturing, the AE energy rate points are denser and more surge points are present before the sample ruptures compared with water fracturing, indicating that quite a number of micro-cracks are generated in nitrogen fracturing and only very few micro-fractures are produced in water fracturing.
