Abstract: A steam assisted gravity drainage (SAGD) system having a hub module operatively coupled to a pipe rack module. The pipe rack module having a first side and a second side. An injection module operatively coupled to the pipe rack module. The injection module providing a high pressure steam via at least one high pressure steam line to an injection well. A production module operatively coupled to the pipe rack module. The production module receiving an emulsion into a produced emulsion line from at least one production well. The hub module permits the injection module to be located on either the first side or the second side of the pipe rack module and the production module to be located on either the first side or the second side of the pipe rack module.
