Abstract:
A subsea template/manifold system for phased development of subsea well at a first site capable of being expanded to develop one or more additional wells at a second site, the system comprising:at least one flowline extending downwardly from a surface facility to the first well site for directing flow away from the first well site;at least one subsea wellhead;a template base having one or more receptacles capable of receiving a wellhead;a subsea tree assembly mounted on said wellhead and having a tree-to-manifold connection port;a saddle manifold mounted on said template base and having at least one production header for directing flow from said tree assembly to said flowline, said manifold also having a valve for isolating the production header from said tree assembly;said production header having (a) a first end in fluid communication with said flowline, (b) a connection providing fluid communication with said tree-to-manifold connection port, and (c) a second end; said second end being extendable to the second site without preventing a well receptacle from being able to accommodate a well; anda remote control center for controlling operation of said tree assembly.
