As a primary step, the mannequin is studied for a simple configuration involving two boreholes every equipped with a single U-tube, linked in a single network (NBiS model). Then, the mannequin is tailored to a case the place the number of boreholes nB is set by the consumer. Finally, the final ambientadorescaseros.com model of the model (NBiS mannequin) is fitted to nB 4-tubes boreholes piped to type two independent circuits. It additionally allows the consumer a mixed configuration with parallel branches of in-sequence boreholes.

Each of the three variations of the NBiS mannequin has been implemented as a Type in the TRNSYS surroundings. These models have been efficiently verified using inter-mannequin comparisons. Lastly, an example of annual simulations for a solar group is offered, where the seasonal borehole thermal energy storage is modeled using a TRNSYS Type of the NBiS suite of fashions. Matching procedures are sometimes utilized costumbres.net in reservoir manufacturing to enhance geological models. In reservoir engineering, history matching results in update petrophysical parameters in fluid move simulators to suit the results of the calculations with observed information. In the identical line, seismic parameters are inverted to allow the numerical restoration of seismic acquisitions. However, it’s well-known that these inverse problems are poorly constrained.
The work consists in developing numerical prototypes of a 3-D fluid move simulator and a 3-D seismic acquisition simulator. Then, in implementing the coupled inversion loop of the permeability and the acoustic impedance of the 2 fashions. We can therefore check our concept on a 3-D sensible case. Comparison of the coupled matching with the two classical ones demonstrates the efficiency of our methodology. We scale back considerably the variety of potential options, and then the number of situations. In addition to that, the augmentation of data results in a pure improvement of the obtained fashions, especially within the spatial localization of the permeability contrasts.
An example of application of topological optimisation was performed with geostatistical models together with a really strong change of topology. The obtained outcomes are promising. forty seven refs. This thesis presents a study of the strategies for modeling boreholes in sequence used for seasonal borehole thermal energy storage, along with a description and verification of an analytical mannequin suited for large bore fields (â¥ a hundred boreholes). A detailed study of present fashions for seasonal borehole thermal power storage using in-sequence bore fields is performed beforehand, to establish modeling needs. A model entitled NBiS is offered on this thesis.

The improvement is important, at the similar time within the distribution of the 2 inverted parameters, and within the rapidity of the operation. This work is an important mantenimiento de flota step in a method of data integration, and leads to a greater reservoir characterization.
The concept of this unique work is to simultaneous match both the permeability and the acoustic impedance of the reservoir, for an enhancement of the ensuing geological mannequin. To achieve this, each parameters are linked using both noticed relations and/or the basic Wyllie and Carman-Kozeny (porosity-permeability) relationships. Hence production information are added to the seismic match, and seismic observations are used for the permeability restoration.

During this thesis, we also identified the likelihood to modify the topology of the domain utilizing the idea of topological gradient. The development of this topological optimisation methodology was made possible due to the efficiency of the adjoint state methodology. The adaptation cost of the results was small, especially for the calculation of the sensitivities with respect to the place of small size obstacles. The proposed purposes concern the identification of the thickness and the width of channels of the place and the dimensions of faults, of top floor and reservoir limits.
