I was reading recently a publication from some old colleagues in BP, entitled "Development of an Active Global Lessons Learned Database". You can order this paper from here - it's reference number is SPE 64529, and it was published in 2000. It's great overview of the sort of technology you need to support a Lessons Learned Program, and it also contains a set of success-case stories of knowledge transfer, and one case where knowledge transfer would have been possible, but didn't happen. There are some technical terms in there, but you can follow the principles.
"The West of Shetland (WoS) team received a pushed lesson from the Southern North Sea (SNS), team concerning the incompatibility of a double shoulder connection. This identified a “new” WoS risk since they planned to run similar connections. Mitigating actions were put in place to significantly reduce the risk of twist off and the operation was performed with no lost time. The power in this example is that the WoS team would not normally consider SNS a relevant analogue due to the different type of operations, deepwater drilling from semi submersibles versus jack up drilling in shallow water. Based on the WoS profile stating what equipment they were interested in, they were in fact comparable, and the relevant SNS lesson was pushed to the WoS team".
"The SNS team have validated over $3,500,000 worth of lessons in their ongoing operations and are using them to demonstrate an auditable continuous improvement process to add value to future planning. An unexpected bonus that they have observed is that through using LINK they have built stronger lines of communication between rigsite and office based staff. In their team the wellsite supervisors and engineers can now see that their ideas for improvements are being used to do things better in future and not being lost in the system".
"An Alaskan Shared Services Drilling operation suffered a High Potential Incident where a 30lb derrick pin dropped 85feet to the rig floor during a rig move. It narrowly missed a roughneck tearing the pocket of his coveralls. The team involved entered a safety bulletin into LINK and put in place mitigating actions to ensure repeat occurrence could not happen in any other BP Amoco Alaskan operation. The safety bulletin was pushed out to all teams globally to ensure that mitigating actions could be put in place at all relevant operations".
"The Valhall team in Norway drilled a long horizontal chalk section using a rotary steerable tool, which was a new approach compared to their normal practice of using a PDM. The section was drilled significantly quicker than normal. A wiper trip with a hole opener was deemed necessary prior to running the production liner. The same stiff BHA that had been utilised on previous wells was used because of the requirement to get the 1600 metre horizontal liner to bottom. However, the BHA became stuck in the chalk section. The BHA was pulled free after acidising, but the stuck pipe incident made the wiper trip 24 hours longer than necessary and cost $120,000 in lost time. After the incident, the team accessed other teams’ lessons using the same rotary steerable system through the search engine of LINK. They found 11 recent lessons with two directly relevant. With hindsight the team realised that if they had known about the other teams recent lessons they would have modified their risk picture related to the BHA design. This would have significantly reduced the risk of stuck pipe occurring".
