	Thermal history modelling - Wikipedia, the free encyclopedia
		Thermal history modelling is an exercise undertaken during basin modelling to evaluate the temperature history of stratigraphic layers in a sedimentary basin.
		The thermal history of a basin is usually calibrated using thermal indicator data, including vitrinite reflectance and fission tracks in the minerals apatite and zircon.
		The temperatures undergone by rocks in a sedimentary basin are crucial when attempting to evaluate the quantity, nature and volume of hydrocarbons (fossil fuels) produced by diagenesis of kerogens (a group of chemicals formed from the decay of organic matter).

	QUANTITATIVE MODELING OF PETROLEUM SYSTEMS AND BASIN PROCESSES: PAST, PRESENT, AND FUTURE
		Basin modelling has loosely been defined as the numerical modelling of any process that takes place in a basin.
		Petroleum basin modelling was originally developed and used by oil companies to quantitatively understand the generation, migration, and accumulation of hydrocarbons in basins to better predict the location, type, and amount of oil and gas.
		More recently, basin models have become more widely available and they are now being used to study a variety of physical, chemical, and thermal processes affecting basins.

	Integrating basin modelling and OpendTect - OpendTect.org
		Basin modelling tools have been traditionally used to study basin modelling, source rock maturation, hydrocarbon generation and expulsion.
		Modelling petroleum systems in a basin with a high degree of confidence requires the ability to calibrate migration paths, hydrocarbon kitchens and all other factors that influence and make up the petroleum system.
		Therefore, the method for integrating detection of fluid migration paths in seismic data with 3D basin modelling is proven to be a new important contributor in the task of reducing exploration risk by increasing the confidence level on model predictions.

	Why conventional basin modelling of fluid flow, overpressure and porosity doesn’t’ work (Site not responding. Last check: 2007-10-08)
		Basin modelling of porosity and fluid pressure development in sedimentary basins almost exclusively hinges on relationships between porosity and effective stress.
		Modelling with porosity vs. effective stress relationships demonstrated that today’s porosity and pore pressures could be reproduced by the modelling.
		Basin modelling of compaction solely based on porosity vs. effective stress relationships should therefore be terminated, and substituted by modelling which also includes stress — insensitive processes for porosity reduction.

		Basin analysis, structural evolution and basin modelling of synorogenic sediments: Mid-Cretaceous of the eastern part of the Northern Calcareous Alps (Austria).
		Basin subsidence and sedimentation was controlled by tectonic movements, especially the overthrusting of nappes from the southern part of the Northern Calcareous Alps.
		Such quantitative models for the interplay of tectonic forces, basin subsidence and sedimentation can be applied to other piggyback-type basins within fold-and-thrust orogens and are of interest in the future search for oil and gas within such complex orogens.

	OilTracers L.L.C. - Using Basin Modeling (Basin Modelling) to Reduce Petroleum Exploration Risk
		Basin modeling (also spelled basin modelling) is the process of using either proprietary or commercially available software to assess charge risk by integrating diverse geological and engineering data types into a model of one or more petroleum systems active in an area being explored.
		Basin models are constructed by integrating various types of geological and geochemical data (e.g., see Welte et al., 1997, for a review).
		Which basin modeling software package is appropriate for a given project also depends on a variety of factors, including the project goals, the available data (geological and geochemical) for constructing the model, and the financial resources available for the project.

	River Basin Modelling Systems (Site not responding. Last check: 2007-10-08)
		A state-of-the-art coupled atmosphere/hydrology modelling system is being developed by coupling the UK Meteorological Office's 'unified' model to the UP system, and the first application of the coupled system will be for the Arkansas-Red River basin, as a contribution to GCIP (Figure 7).
		In some ways an UP element is similar to a multi-compartment conceptual model used for modelling the water balance of basins, as it uses simple functions to relate the fluxes out of each compartment to the water storages in the compartments, and to a few other state variables.
		The parametrization models are physically-based, distributed models, similar to sub-components of SHETRAN.

		Basin modelling is a powerful tool for investigating the hydrocarbon system and its evolution through geological time in the sub-surface.
		Commercial basin modelling packages currently enable many aspects of hydrocarbon generation, migration, trapping and leakage to be simulated in 3D through geological time.
		The ability to build models quickly and run multiple simulations, particularly where data are scarce, allows the explorationist to pose ‘What if ?’ questions to investigate the sensitivity of the petroleum system to critical parameters, such as source rock properties.

	Hydrocarbon prospectivity in the Central Irish Sea Basin
		This is particularly important in sedimentary basins which have undergone a series of palaeo-thermal episodes, as a result of which a given source rock horizon may have reached maximum maturity at different times in various locations across the basin.
		The basin is bounded to the north by the Mid Irish Sea Uplift and to the south it is separated from the St. George's Channel-Cardigan Bay Basin by the offshore extension of St. Tudwal's Arch (Figure 1).
		This model is calibrated using a combination of laboratory and geological data from a variety of sedimentary basins around the world.

		We focus on the hydrogeologic and hydrodynamic response of the basin fill to its geodynamic evolution and the relation between this response and present-day physico-chemical characteristics of the rock and fluids in the basin.
		Quantitative knowledge on the values and distribution of these ´deviating´ permeabilities, as provided by the basin modelling, is of importance for a correct evaluation of the units for exploration and production of geothermal energy and underground storage of energy and energy residues.
		Model results indicate that the unsteady state temperature conditions in the Broad Fourteens Basins are in large part due to the low surface temperatures during the later part of the Pleistocene.

	Physically-based River Basin Modelling Within a GIS: The LISFLOOD Model (Site not responding. Last check: 2007-10-08)
		A number of specific routing methods are needed in a GIS for hydrologic modelling, amongst those numerical solutions of the Saint-Venant equations, such as the kinematic wave approximation for transport of surface water in a landscape.
		Ideally, for transport modelling one should be able to control the amount and velocity of water (or any other material) through the network: one would want to have 'access' to the algorithms describing this transport.
		In two pilot transnational European river basins the flooding problem is investigated using the LISFLOOD model: the Meuse catchment, covering parts of France, Belgium and The Netherlands, and the Oder basin, covering parts of The Czech Republic, Poland and Germany.

		Petroleum geology is a term used to refer to the specific set of geological disciplines that are applied to the search for hydrocarbons.
		Gas generation starts at similar temperatures, but may continue up beyond this range, perhaps as high as 200°C. In order to determine the likelihood of oil/gas generation, therefore, the thermal history of the source rock must be calculated.
		This is performed with a combination of geochemical analysis of the source rock (to determine the type of kerogens present and their maturation characteristics) and basin modelling methods, such as backstripping, to model the thermal gradient in the sedimentary column.
