This shale gas is one of the unconventional oil and gas fields that require a separate technology from the existing production method.

This hydraulic fracturing technology is a method of collecting shale gas by injecting or filling compounds such as water, sand, and fluid at high pressure after reaching the target point of the shale layer through horizontal well drilling to create and maintain cracks in the shale layer.

In addition, due to the recent oil gas price fluctuations and the midway abandonment of the oil and gas field business due to COVID-19, appropriate closure measures for oil and gas field production facilities or environmental protection methods or environmental restoration projects due to business closure are not being implemented.
