A scientific drilling program in northeast China's Heilongjiang Province, called the Songke Second Drilling Well, has just completed an exercise that successfully reached 7,018 meters underground, reports People's Daily.
《人民日报》报道,黑龙江省一处科学钻井项目松科二井成功钻入底下7018米。
It was the deepest drilling point in Asia since the International Continental1 Scientific Drilling Program was established 22 years ago.
It took the team four years to reach that depth since drilling started in April 2014.
Aside from the technical achievement of the drilling itself, the program has highlighted the potential for the Songliao Basin to be a site for deep shale2 gas extraction or geothermal energy production. Samples drawn3 from the drill site have also provided evidence of what the climate was like during the Cretaceous period 145 to 65 million years ago.
