Title: METHOD AND APPARATUS FOR PRODUCTION LOGGING TOOL (PLT) RESULTS INTERPRETATION
Abstract:
Methods and systems are presented in this disclosure for evaluation of formation properties (e.g., permeability, saturation) based on interpretation of data obtained by production logging tools (PLTs). Based on the PLT data, a production rate for a component (e.g., production fluid) produced by a wellbore can be determined, and a distribution of a property of the component can be initialized along a length of the wellbore. A simulated production rate for the component can be calculated, based on the distribution of the property using a simulator for the wellbore. The distribution of the property can be iteratively adjusted based on the production rate and the simulated production rate, until convergence of the distribution for two consecutive iterations is achieved. A reservoir formation model used for operating the wellbore can be updated based on the adjusted distribution of the property of the component.
