A system for steam-assisted gravity drainage for heavy oil production has a first well, a second well, a first platform connected to the well head of the first well so as to inject steam into the first well, and a second platform connected to the well head of the second well for producing heavy oil from the second well. The platforms are arranged in parallel flow relationship. Each of the platform has a first level with flow lines extending longitudinally therealong and a second level located above the first level and having piping connected to the flow lines of the first level. The second level includes valves and controllers cooperative with the piping. The platforms are modular in nature and can be connected to other platforms.

I claim: 1. A system for heavy oil production comprising: a first well having a well head; a second well having a well head; a first means connected to said well head of said first well, said first means for injecting steam into said first well; and a second means connected to said well head of said second well for producing heavy oil from said second well, said first and second means arranged in parallel flow relationship, each of said first and second means comprising: a first level having a plurality of flow lines extending therealong, said flow lines being exposed on opposite sides thereof; and a second level located above said first level, said second level having piping connected to said flow lines of said first level, said second level having a valve and controller cooperative with said piping, said second level supporting cable trays receiving electrical and communication cables thereon, said piping having a swivel head connection suitable for joining to the well head or to a swivel head of an adjacent piping. 2. The system of claim 1, said second level having a walkway formed thereon. 3. The system of claim 2, further comprising: a stairway extending from said first level upwardly to said walkway of second level. 4. A system for heavy oil production comprising: a first piping assembly having a first level and a second level, said first level having a plurality of flow lines extending longitudinally therealong, said second level having a piping thereon in communication with said flow lines of said first level, said second level located above said first level, said first and second levels of said first piping assembly are simultaneously transportable and supported by a single frame; and a second piping assembly having a first level and a second level, said first level of said second piping assembly having a plurality of flow lines extending longitudinally therealong, said second level of said second piping assembly having a piping thereon in communication with said flow lines of said first level of said second piping assembly, said first and second levels of said second piping assembly are simultaneously transportable and supported by a single frame, said piping of said second piping assembly selectively connected to said piping of said first piping assembly, said first piping assembly being joined in end-to-end relationship with said second piping assembly and being formed into a string of basic units connected to each other with said flow lines, each unit being parallel to a line of injection or production wells and having connection pipes perpendicular to said line of injection or production wells. 5. The system of claim 4, said plurality of flow lines of each of said first and second piping assemblies being exposed on opposite sides thereof. 6. The system of claim 4, said piping of one of said first and second piping assemblies having a swivel connection thereon suitable for connection to a well head. 7. The system of claim 4, said second level of each of said first and second piping assemblies having valves and controllers interactive with said piping. 8. The system of claim 4, said second level support cable trays thereon receiving electrical and communications cable thereon, the electrical and communication cable of said second level of one of said first and second piping assemblies being connectable to the electrical and communication cables of the second level of the other of said first and second piping assemblies. 9. The system of claim 4, the second level of each of first of said piping assemblies having a walkway thereon, the walkways being aligned and continuous with each other. 10. The system of claim 9, further comprising: a stairway extending from said first level of said first piping assembly to said walkway of said second level of said first piping assembly. 11. A method of installing piping systems for heavy oil production comprising: forming a first platform having a first level and second level with flow lines extending along said first level and piping communicating with said flow lines and extending along said second level, said first platform constructed from a single frame, said first and second levels of said first platform being simultaneously transportable; forming a second platform having a first level and second level with flow lines extending along said first level and piping communicating with said flow lines and extending along said second level, said second platform constructed from a single frame, said first and second levels of said second platform being simultaneously transportable; transporting said first and second platforms to first and second well heads; connecting said piping of said second platform to the piping of said first platform; connecting said piping of said first platform to the first well head; and connection said piping of said second platform to the second well head. 12. The method of claim 11, further comprising: forming a third platform having a first level and a second level with flow lines extending along said first level and piping communicating with said flow lines; forming a fourth platform having a first level and a second level with flow lines extending along said first level and piping communicating with said flow lines and extending along said second level; transporting said third and fourth platforms to third and fourth well heads; connecting said piping of said third platform to said piping of said second platform; connecting said piping of said fourth platform to said piping of said third platform; and connecting said piping of said third and fourth platforms to the third and fourth well heads. 13. The method of claim 12, further comprising: arranging said third and fourth platforms so as to be in parallel flow relationship with respect to said first and second platforms. 14. The method of claim 12, said first well head being a production well, said second well head being an injection well. 15. The method of claim 11, said step of forming comprising: extending cables along cable trays on said second level of said first platform; extending cables along a cable tray on said second level of said second platform; and connecting the cables of said first platform with the cables of said second platform through a connection box. 16. The method of claim 11, said first and second platforms having substantially identical configurations. 17. The method of claim 11, said step of connecting said piping of said first platform to said first wellhead comprising: forming a swivel head on said piping of said first platform.
