This work develops the physical-mathematical anisotropic model of electromagnetic fracturing, applied to petroleum reservoirs. This model considers the resonance frequency on any formations with hydrocarbon content and anisotropic medium. Finally, develops electromagnetic fracture design in 3D to any formation applied.

This paper proposes and develops the physics and mathematical models for electromagnetic fracturing, applied to clay formations. This work has as objective to develop a physical and mathematical model, considering the resonance frequency of clay rocks. Therefore, is required the static characterization of clay, to generate induced fractures with magnetic field. A mathematical model is presented, wich has allowed to conclude that it is possible to develop electromagnetic fracturing; thus, initial demonstration was made with electromagnetic sources: microwave magnetrons, and reported demonstrations in the literature are discussed.

Models to determine the static reservoir temperature by pressure testing
In this work, two models are presented, which have the goal of estimating the formation static temperature during drawdown and build up pressure well testing. A modification was derived to estimate the static temperature of a reservoir by through the analysis of temperature data recorded during a drawdown pressure test. Based on this derivation, two methodologies are presented with a practical approach, whose solution is validated with a field case that includes results, error rates, discussion of results and conclusions.
Likewise, the modified Horner method is presented to estimate the temperature of a reservoir during a pressure build-up test, the modification is done using a correction factor that consists of multiplying the result obtained by the solutions of Hasan and Kabir (1991) applying the principle ofsuperposition in time by the slope of the Horner plot and add it to the temperature obtained from a Horner plot. Two synthetic examples are presented which include a methodology to apply, results, error rates and discusión of results.
Fractional model of heat transfer during fluid injection in naturally fractured reservoirs.
In this work a fractional model of heat transfer during injection of fluids into naturally fractured geothermal reservoirs is presented, which has the goal of analyzing the subdiffusion of heat from or to the adjacent strata ones, as well as in the heat exchange from the matrix to the fractures when thermal equilibrium in the fluid rock system has not yet been reached. An equation was solved by means of the Laplace transform that takes into double fractionality account; one for the heat conduction equation of the adjacent strata and the other in the derivative of the convolution integral that models the heat exchange between the matrix and the fractures. Different type curves are presented in order to analyze different heat subdiffusions in fractured media corresponding to different values
of permeability.
