E&I draftsman- software used in oil and gas,petrochemical?

can anyone tell me the various software used in the design of E&I system in oil and gas, petrochemical industries?. In case if autoCAD means I want to know the details about which type?

Being a Instrmentation Engineer i have used quite a few softwares below.

1.SPI: Smart plant instrumentation
2. Autocad -for drawing electrical diagrams.I used to use it in my early days as a software for drawing P&IDs.
2. Smart Draw -specifically to draw P&IDs.
3. Matlab- there are numerous applications i used it for.
4. Labview- you can get the free trial and its an alternative to SCADA developed by major players such as Siemens,Schiender etc.
5. Google earth- its a must have application when you are involved in surveying a project which needs to executed wirelessly with technogies such as Rf and in case you are using some other communication protocol if data needs to be put on a map for the client-you need latitude and longitude of each and every stations.
6. Modscan - I use it while working with remote terminal units when i need to know to test logics -specially for searching bugs.
