Abstract: The invention describes a method for creating a digital archive for information generated in drilling and well operations, as well as for planning such operations. The invention further describes a system for linking, storing and accessing the information in a data store, and graphical user interfaces enabling users to accessing information made available in the system. The described system allows internet based (cloud), thus allowing users to access information from different physical and virtual location.
