Petroleum system evaluation by basin modeling.

Abstract

The petroleum system is defined by Magoon and Dow (1994) as a natural system which includes all geological and geochemical elements and processes essential to oil and gas accumulation. The concept itself is not new, but they reviewed and introduced a simple method to evaluate the petroleum systems. Basin modeling is one of computer simulation techniques which model generation, migration and accumulation of oil and gas in a sedimentary basin. In this paper, the emphasis is focused on that multi-dimensional basin modeling is one of the best techniques to evaluate the petroleum systems, since it can integrate many processes with quantitative evaluation on the history of sedimentary basins. Explorationists generally have several hypotheses or scenarios by the evaluation of present data. The artificial experiment by basin modeling can be compared with these hypotheses. Since each module forming whole basin modeling package is developed by the

Burial and Thermal History Modelling of the Mannar Basin, Offshore Sri Lanka

“…The measured vitrinite reflectance data were used to calibrate the thermal history of the Mannar Basin. The processes involved in forward modelling using SIGMA-2D software were described in detail by Okui et al (1996) and Okui (1998).…”

“…In this study, SIGMA software developed by JNOC (now JOGMEC) was used for 2D-basin modeling (Okui, 1997;1998) . The modelled line is a regional NW-SE line passing through the field in the studied area (Fig.…”

“…Most of rift basins in Southeast Asia were formed in Cenozoic related with the India-Eurasia collision followed by easterly movement of Indochina and expansion of South China Sea (Patriat and Achache, 1984) . The Cenozoic rift basins in Southeast Asia are known to have high petroleum potential and the petroleum system of each basin has been analyzed and characterized (Okui, 2005;Okui et al, 1997;1998;Shimada and Aoyama, 2005) . Many studies revealed the presence of two types of source rocks in the petroleum basins in Southeast Asia.…”

One improved burial history recovery method and computer model establishment

“…Papers (Paweł and Magdalena 2012;Van Keer et al 1997;Senglaub et al 2006;Narkiewicz et al 2010) adopted the burial history results simulated by PetroMod software, designed in Germany, as the foundation of further researches. The SIGMA-2D basin modeling system (version 6) of the Japanese Oil, Gas and Metals National Corporation (JOGMEC), which described in detail by paper (Okui 1998), was used in paper (Premarathne et al 2016), to simulate a basin's burial and thermal history along a 2D cross-section. In addition, in paper (Galushkin et al 2014), The GALO computer program was used to model the thermal and burial histories of the Murzuq and Ghadames Basin, Libya.…”

“…Calculate steps of back-stripping method have been illustrated in other papers (Okui 1998;Jiaren and Mingde 1995;Kaijun et al 2005). This paper has made follow consideration based on former researchers.…”
