Knowledge Management implementation in the high risk and capital activity of an Oil and Gas company has been big challenge, especially to achieve the future Company Wide Knowledge Culture. The program, including data management, is a part of keeping the company continuous improvement that focuses on exploration and production activities. The implementations include all needed and standardised databases, knowledge repository, e-Learning and e-Library through knowledge portal programs as well as running the community of practices (CoP). The program must be assessed, measured, analysed to find the gap, improve and then control it to meet the company business goals. In order to meet the approved standards, benchmarking must be done internally and externally, to assess, analyse and report the results to all employees and management to communicate what level actually has been implemented and to improve our KM awareness as well as to immediate enforce and enhance the initiatives necessary. By benchmarking with specific method or to the other KM implementers, we can learn what the program gaps and weakness are and put some planning effort for further sustaining program.
