A system and process for producing synthetic crude oil from produced fluids of an oil well is disclosed. The system comprises a separation plant for producing an associated gas stream from produced fluids a membrane unit comprising a plurality of polymer membranes to provide a COenriched permeate stream and a COdepleted product gas stream, a gas conversion plant for converting the COdepleted product gas stream into a synthetic crude oil and a heat exchanger adding heat to the associated gas stream so that the membrane unit operates at a temperature of at least 80&#xb0; C. during separation of the associated gas stream using the membrane unit. A process using the aforementioned components, including separation of the associated gas stream using the membrane unit at a temperature &#x3e;80&#xb0; C., into a COenriched stream and a COdepleted product stream, is also described.
