Engineers from the Perm National Research Polytechnic University have found a way to extract oil in the Arctic without melting permafrost, which can cause a well collapse.
In regions with permafrost, oil production requires heating oil deposits in the bowels of the earth using hot steam and other methods. However, this process is often accompanied by the melting of permafrost, which threatens the collapse of the well and equipment failure.
"They (engineers) created a virtual twin of the well with a 95% forecast accuracy. The development will allow us to calculate the ideal heating mode, which will melt the oil, but preserve the permafrost and protect the well from destruction," the university's press service said.
The test results showed the high accuracy of the mathematical model in all operating modes of the well, tass.ru notes.
