As liquid nitrogen brings about thermal damage to rock when it comes into contact with a
reservoir, it can be used as a fracturing fluid under proper engineering conditions. To …

Liquid nitrogen has been successfully used as a fracturing fluid in petroleum engineering.
When liquid nitrogen is pumped into a well, the physical conditions of the reservoir rocks will …

As an innovative technology for the stimulation of coalbed methane, liquid nitrogen cold
soaking can produce more fractures in coal body and effectively increase the permeability of …

Freezing by liquid nitrogen (LN 2) can noticeably alter the rock structure of rocks, which can
find application in the extraction of clean natural gas for shale gas reservoirs. More natural …

Cryogenic nitrogen fracturing can provide a new insight into the stimulation of deep shale
gas reservoirs. In order to investigate the physical and mechanical behaviors of high …

Liquid nitrogen (LN) fracturing is an efficient technology for the development of
unconventional gas resources. Due to continuous injection of cryogenic LN, the reservoir …

When cryogenic liquid nitrogen (LN 2) comes into contact with deep reservoirs, it will bring
about serious thermal damage to rock pore structure. Therefore, LN 2 pretreatment on …

Eagle Ford shale formations have great hydrocarbon potential to minimise the supply and
demand problems of the overgrowing population. Whereas, due to reduced permeability …

The most distinct feature of liquid nitrogen fracturing is the sharp reduction in temperature
around the rock when liquid nitrogen comes in contact with the reservoir. This condition …

As liquid nitrogen is injected into a wellbore as fracturing fluid, it can rapidly absorb heat
from warmer rock and generate cryogenic condition in downhole region. This will alter the …
