successfully for the exploitation of salt, and marked the beginning of
Sichuan's salt drilling industry. Shaft wells were sunk as early as 220 BC in the Sichuan and Yunnan Provinces. By 1035 AD, Chinese in the Sichuan area were using percussion drilling to recover deep brines, a technique that would not be introduced to the West for another 600 to 800 years. Medieval and modern European travelers to China between 1400 and 1700 AD reported salt and natural gas production from dense networks of brine wells. Archaeological evidence of Song dynasty salt drilling tools used are kept and displayed in the

Chinese have been using brine wells and a form of salt solution mining as part of their civilization for more than 2000 years. The first recorded salt well in China was dug in the Sichuan province around 2,250 years ago. This was the first time that ancient water well technology was applied
