It is of multidisciplinary nature, and includes disciplines like geophysics, sedimentology, structural geology and geochemistry. A knowledge of the behaviour of the lithosphere is essential if we are to understand the initiation and development of sedimentary basins.lithosphere This module is focused on extensional basins. The formative mechanisms of sedimentary basins fall into three classes: a) loading on the lithosphere causes deflection, and therefore subsidenceloading thinning thinning b) thinning of the lithosphere by mechanical stretching is accompanied by fault-controlled subsidencethinning of the lithosphere c) purely thermal mechanisms, such as heat conduction.

This step involves transferring the seismic profile into the modelling tool. The next step will be to simulate a geohistory for the geological section. It is necessary to make a complete geohistory before moving on to any of the other tasks. During the subsidence analysis you will draw the work you completed in the geohistory reconstruction to constrain the model.The purpose of this task is to calculate the palaeo heatflow over the section. The temperature modelling depends on the calculated heat flow history. The final step in this module is the source rock maturation modelling. This depends on the temperature history of the basin, and on the time. Possible HC migration modelling follows, when the maturity is calculated. Please note the dependencies in the modelling tasks, and that the uncertainty increases during the modelling tasks. Back

As input an interpreted seismic section is the best starting point for building a geological model. This includes geometries and ages of the various horizons. In addition you need information about the 1) time to depth conversion factors. If the section is in seismic two way travel time, it has to be converted to depth. In this case, you need conversion factors. 2) palaeo water depths. 3) eroded or non-depositional surfaces. This includes information on the magnitude of erosion and the time-span of the non-deposition. 4) lithological boundaries and lithology types. Many important input parameters are tied directly to lithofacies, e.g. porosity-depth trends.

This can incorporate a high resolution sequence stratigraphic framework, and structural reconstruction of normal and reverse faults. The geohistory reconstruction provides the basis for all additional geological modelling on the section. It is thus important to do the modelling as correct and realistic as possible. The aim of the geohistorical analysis is to get the basin geometry through time correct.geohistory reconstruction It is of special importance to restore the faults in a proper manner.

Geohistory reconstruction relies primarily on the decompaction of the stratigraphic units to their correct thickness at the various times in the evolution - in addition to fault restoration and corrections due to palaeo water depth variations. The decompaction of stratigraphic units requires the variation of porosity with depth to be known. Estimates of porosity from boreholes suggest that normally pressured sediments exhibit an exponential relationship between porosity and depth. It is given on the form o e- cy where is the porosity at any depth y, o is the surface porosity and c is a coefficient that is dependent on lithology and describe the rate at which the exponential decrease in porosity takes place with depth. The decompaction technique seeks to remove progressive effects of rock volume change with time and depth. One by one layer is removed, and the layers underneath are decompacted. Any compaction history is likely to be complex, being affected by lithology, overpressure, diagenesis and other factors. Consequently, what are needed are some general porosity-depth relationship which hold good over large depth ranges.

Without fault restoration the basin geometry through time will, in many cases, be incorrect. This will affect the estimated temperature regime of the basin, and thus the predicted maturation history. Not less important is the insight into the geometry of possible hydrocarbon migrition pathways and traps through time. There are several different methods for fault restoration. We are using vertical simple shear. It is found that this method give very good results, appropriate for basin modelling purposes. The method is called vertical shear method of the following reason: If you think of a fault block as consisting of a deck of cards, the cards remain vertical throughout the fault restoration process. During the reconstruction, the cards are translated up the fault system until the top timeline is continuous across the fault surface. Once the bars have been moved horizontally, their vertical position are determined by drawing upwards from their new positions along the fault plane. The resulting displacement has significant lateral as well as vertical translation. Back

Isostasy is the principle of Archimedes applied on the earths upper layers. It is one of the main processes operating in basin formation.lithosphere The theoretical isostatic deflections are calculated due to the loading/unloading of sediments and water through time. Isostatic movements are often calculated using an Airy approximation. This assumes that the compensation takes place locally and instantaneously over geological time scales.

Crust: The crust is an outer shell of relatively low density rocks. The oceanic crust is thin, ranging from approximately 4 to 20 km in thickness, and with an average density of 2900 kg m -3. The continental crust is thicker, ranging from 10 to 70 km, and with an average thickness of around 35km. Information on the density of crustal rocks has been obtained largely by observations on seismograms, coupled with laboratory experiments. The existence of a low velocity crust was discovered by the geophysisist Mohorovicic shortly after the turn of the century. The boundary between the crust and mantle is called Moho. The Moho can vary in depth considerably over relatively short distances. Mantle: The mantle is divided into 2 layers, the upper and the lower mantle. The upper mantle extends to about 650-700 km. The lower mantle extends to the outer coreat 2900 km. Back Read more : about the mechanical division of the earth

One of the mechanical zoneations of interest in basin studies is the diffrentiation between the lithosphere and asthenosphere. This is because the vertical motions in sedimentary basins are responses to deformations of this zone. Lithosphere: is the rigid outer shell of the Earth, comprising the crust and upper part of the mantle. It is of particular interest to note the difference between the thermal and elastic thicknesses of the lithosphere. It is generally believed that the base of the lithosphere is represented by an isotherm of 1100-1300 o C, at which mantle rocks approach their solid's temperature. This defines the thermal lithosphere. The rigidity of the lithosphere allows it to behave as a coherent plate, but only if the upper half of the lithosphere is sufficiently rigid to retain elastic stresses over geological time scales. This is the elastic lithosphere. The thickness of the elastic lithosphere varies around the globe. In our area the thickness is estimated to 1 to 40 km. Back

The tectonic subsidence is commonly deduced by the McKenzie model. McKenzie showed that sedimentary basins could form when the lithosphere is stretched, resulting in reduced crustal thickness and upwelling of hot mantle material. After the stretchingMcKenzie model event the surface will subside due to thermal contraction of the lithosphere (see next page). The sum of the isostatic calculations and the tectonic modelling will be compared with the observed subsidence (calculated by the geohistory analysis). The amount of stretching is then the tuning parameter. When the fit is acceptable, the amount of stretching over the basin is quantified. And simultaneously, the palaeo heat flow history is found. This is again input to the temperature modeling.sum of the isostatic calculationsheat flow historytemperature modeling Look on a flow diagram visualising this prosess

Hydrocarbon migration (also termed secondary migration) concentrates petroleum into specific sites (traps) where it may be commercially extracted. The mechanics of hydrocarbon migration from source to reservoir are well studied. The main driving forces behind the migration is buoyancy (caused by the density contrast between the petroleum and pore water), and pore pressure gradients which attempts to move all pore fluids (both water and petroleum)to areas of lower pressure.
