The invention provides methods of producing methane that include: producing formation fluid from a subsurface in situ conversion process and separating the formation fluid to produce a liquid stream and a first gas stream. The first gas stream includes olefins. The first gas stream is contacted with a hydrogen source in the presence of one or more catalysts to produce a second gas stream. Steam, carbon monoxide, and/or hydrogen may be present or added to in the first stream during contacting. The second gas stream is contacted with a hydrogen source in the presence of one or more additional catalysts to produce a third gas stream that includes methane.
