    The Type of Kerogen or Organic material is the #1 dictating Factor. Oil comes from Type I Lipid (Alginite) source or a Lipid/Humic mix found in ancient lakes and marine settings. Coal is purely Humic in nature and is found in brackish or fresh water settings. Gas can be generated from either source depending in thermal maturity and time. Most Fresh water settings are not sufficiently anoxic so as to preserve lipid material (fleshy bits or fatty acids).
