Previously, hydraullic fracturing was used for the development of unconventional reservoirs, however, due to technical problems and environmental flaws this technique was banned in some countries. Researcher are suggesting that liquid nitrogen fracturing can be remedy to that, which provides micro fractures due to sudden thermal shocks, thus, increasing recovery potential. What are you views in this regards? Which technique should be used?
Respected Sir! It depends on the source availability if the huge amount of water available, hydraulic fracturing is the best method. Besides this, if easy access to liquid nitrogen is available it's also the best choice. We need to focus on the development of the industry. Because no one method is ideal or without any drawbacks. But if in some countries hydraulic fracturing is band .so the uploaded file will help you to understand the liquid nitrogen method.

Hydraulic fracturing:
- Involves injecting a mixture of water, sand, and chemicals into the rock formation at high pressure to create fractures that allow oil and gas to flow more easily.
- The technique is well-established and has been used for many years to develop unconventional oil and gas reservoirs.
- Concerns have been raised about the environmental impacts of hydraulic fracturing, including the potential contamination of groundwater and air pollution.
Liquid Nitrogen Fracturing:
- Involves injecting liquid nitrogen into the rock formation, causing sudden thermal shocks that create micro-fractures in the rock.
- The technique is still in research stage and not yet widely adopted.
- The idea behind this technique is that it would create smaller fractures that are less likely to cause environmental damage, while still increasing the recovery potential of the reservoir.
