Logging

We provide logging and data interpretation services for open-hole and cased-hole exploration and production well operation. We operate six Baker Atlas CLS surface system units, thirteen Baker Atlas ECLIPS system units and five CASE production logging system units in our logging centre. Our logging tools are capable of performing a wide range of logging services for different purposes such as exploration, development, construction and production. We also offer our clients excellent logging data interpretation services from our logging data processing and interpretation center in Yanjiao, Hebai Province, China.

ELIS

The Enhanced Logging Image System (ELIS), a latest logging system developed and fully-owned by COSL, has been gradually gaining recognition in China and Middle-east.

 


FCT

Formation Characteristics Tools (FCT), approved by the PRC’s Ministry of Science and Technology of China, has passed the operation test in Bohai.
