“Chuan-type” coring tools and technologies have been applied in oil and gas fields of CNPC, Sinopec and CNOOC, involving Qinhai, Huabei, Dagang, Sichuan, Tuha, Tarim, Shengli, Zhongyuan, Nanhai and Bohai, as well as foreign counties as Russia, Kazakhstan, Sudan, Algeria, Egypt, Iran, Iraq, Vietnam, Singapore, Indonesia, India and Thailand. In recent 15 years, coring footage approaches 100,000 meters, accounting for over 50% of total coring footage in China, and core recovery is above 95%. The Company, with coring technology No. 1 in China, can provide all categories of coring services, such as conventional coring, gas drilling coring, liner coring, underbalanced coring, horizontal well coring, gel coring and wireline coring. Gel coring ensures core not contaminated by drilling fluid and wireline coring saves drilling time substantially.
“Chuan-type” coring tools have been used in the first shale gas well (Wei 201), the first gas drilling well (Baoqian 1) and the first UBD well (Qiongxi 3) in China, and also have been used in the deepest well (Tashen 1) in Asia.
