Aspects of petroleum migration modelling

Oil and gas assessment of the Kuqa Depression of Tarim Basin in western China by simple fluid flow models of primary and secondary migrations of hydrocarbons

“…2-D basin modeling is applicable during the moderately explored stage, while 3-D basin modeling is applicable during the more explored stage, and both have the capability of simulating secondary migration. Welte et al (2000) summarized and reviewed the following four categories of numerical approaches to simulating secondary migration: multi-phase Darcy flow modeling, flowpath modeling, hybrid method (HM) combining the former two approaches together, and invasion percolation (IP) modeling. To date numerical simulation is still defined by these four categories, though there are certain developments concerning these methods.…”

“…Multi-phase Darcy flow modeling (e.g. Ungerer et al, 1990;Shi et al, 1996;Welte et al, 2000;Scheichl et al, 2003;Shi et al, 2003;Hantschel and Kauerauf, 2009;Mello et al, 2009) is the most comprehensive method but sometimes might be unusable in practice. Flowpath modeling (e.g.…”

“…Flowpath modeling (e.g. Hantschel et al, 2000;Welte et al, 2000;Hantschel and Kauerauf, 2009) is the most efficient method and often a very good approach when data is sparse. HM modeling (e.g.…”

Biodegradation in numerical basin modelling: a case study from the Gifhorn Trough, N-Germany

“…The compositional kinetic model used allows the correct reproduction of petroleum composition and phase behaviour during migration (di Primio and Horsfield 2006). For migration modelling the hybrid-technology of PetroMod was applied, where multi-phase flow in low-permeability lithotypes is calculated based on Darcy's law, whereas in high permeability carrier systems a ray tracing technique is used Welte et al 2000). The main goal of the migration modelling was to reproduce the observed accumulations in the area as well as their respective petroleum phase (black oil in both cases).…”

Reconstruction of the Cenozoic History of Hydrocarbon Fluids from Rifting Stage to Passive Continental Margin Stage in the Huizhou Sag, the Pearl River Mouth Basin

“…However, the nature of petroleum migration pathway is still controversial. Some researchers [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] believed that the petroleum fluids migration is mainly driven by structural morphology, and modeling of petroleum fluids migration pathways can be a powerful tool to reduce exploration risk. Others [27][28][29][30][31] propose that petroleum fluids tend to pass through a high-permeable, thin sandstone bed than through a low-permeable and thick sandstone bed, controlled by the heterogeneity of the porosity and permeability of the carrier beds.…”
