Abstract
Important strategies for the production and management of an oil field are defined based on accurate characterization of the fluids and reservoir properties. Traditionally, pressure data from well tests and production are used to estimate reservoir permeability and porosity. However, in high transmissibility reservoirs, using only pressure data can lead to misinterpretations due to thermal effects and, therefore, errors in the reservoir characterization. Recent works on reservoir characterization have shown that the use of temperature transient data combined with pressure data produces better results. Reservoir parameters can be estimated by solving an inverse problem using the Ensemble Smoother with Multiple Data Assimilation (ES-MDA) method. Recent work using this methodology in a system consisting of a well coupled with a 1-D radial reservoir has shown the potential of this technique on reservoir parameter estimation workflow. This work extends previous analyses considering a producing well coupled with a 2-D non-homogeneous reservoir. The implemented method was able to accurately estimate the permeability and porosity of different regions within the reservoir.
