“…However, a petroleum system is an open system subject to fluid mass flux, and errors may therefore come from element introduction (a major problem in dating with radiometric methods and the reason that absolute dating is rarely applied) (Parnell, 1998). In contrast, relative dating via basin modelling calculations has been used by several authors (Leadholm et al, 1985;Sørensen, 1985;Ungerer et al, 1990;Burley et al, 2000;Skeie et al, 2004) and is the general approach in industry. Karlsen et al (1993), Bhullar et al (1999) and Tseng and Pottorf (2002) combined burial modelling and fluid inclusion techniques to constrain the petroleum charging history in siliciclastic reservoirs.…”
