Figure 6. — Geographic distribution of oil types found in Oman and appoximate `Q' oil migration fairway. Data compiled from numerous sources including Grantham and others (1988), Sykes and Abu Risheh (1989), Guit and others, (1995), Lake (1996), Al-Ruwehy and Frewin (1998), Richard and others (1998), and Terken (1998, in press).
