Coronado Ciencias de la Tierra Tracer tests porous media inverse problem fluid transport non linear optimization methods In the interpretation of inter-well tracer tests to determine reservoir properties in oil and geothermal reservoirs as well as inaquifers, different non-linear regression methods are used. Analytical flow models are employed to fit tracer breakthrough data inorder to determine the free parameters in the models. Non-linearity can yield multiple solutions for the fitting parameters. Traditionally,a single optimization method and several initial parameter values are employed. This procedure is often cumbersome andcomputer time-consuming. Moreover, an initial point close to the global optimum must be provided, what in many field cases isnot available. We propose an approach which employs several optimization methods simultaneously, using a few initial points.Thus, different solutions can be found in a relatively simple way, and the reliability of the solutions is improved. 2005 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56844108 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.44 |
