The present invention relates to a method for calculating the cover effect in the modeling of petroleum systems, comprising: obtaining input lithospheric and sedimentary data; discretizing the model differently in the sedimentary and lithospheric domains; starting the calculation of the cover effect; verifying whether the deposition time corresponding to each sedimentary layer is greater than the present time and whether the basin age is greater than the deposition time corresponding to each sedimentary layer, by refraining from carrying out the method;the verification of whether the deposition time corresponding to each sedimentary layer is less than or equal to the present time and whether the age of the basin is less than or equal to the deposition time corresponding to each sedimentary layer and the verification of whether it is in the collapse period, in which: if it is in the collapse period, the calculation of the collapse; if it is not in the collapse period or if it is after the collapse calculation stage, the calculation of the sedimentation; in the collapse period, the calculation of the advective vertical displacement velocity due to lithospheric thinning for each XY coordinate; the calculation of the fluid flux; the use of finite elements to perform calculations at each instant in time; the performance of the addition of the thermal effect of the lithospheric and sedimentary domains at each time stage.

One objective of the present invention is to provide a miniaturized chromatographic method for the selective extraction of polar compounds from crude oils, which is faster and more economical in terms of sample consumption, solvent volume, and waste generation, without compromising the chemical signature of the sample. Specifically, the method employed was solid-phase extraction (SPE), in online and offline modes, for the prospecting of polar compounds from crude oils, together with H-MPLC, in order to support a greater understanding of petroleum systems through the development of faster, more selective, economical, and environmentally more sustainable analytical and chromatographic methods. Furthermore, the invention also provides to describe an automated multidimensional solid-phase extraction (SPE) chromatographic system, which is applied in said method, as well as to describe some uses of said method.
