Patent number: 7193525Abstract: A method and apparatus for communicating between downhole tools without the necessity of routing the communication through a surface module. Communications sent by downhole tools are examined and extracted downhole. If the communications are intended for other downhole tools, the communications are copied to a downlink and send to a specific intended tool, a group of tools, or all the tools. This is all done downhole, significantly reducing the latency between command and response.Type: GrantFiled: October 21, 2003Date of Patent: March 20, 2007Assignee: Schlumberger Technology CorporationInventors: Shohachi Miyamae, Tetsuya Tanaka, David Santoso, David Mathison
