abstract
Copyright 1998, Society of Petroleum Engineers, Inc. This study presents an approach to exploit full potentials of a production logging run. In the proposed methodology, we seek layer flow contributions, reservoir parameter estimation, and well-performance optimization, in one logging operation. In particular, we match the entire wellbore pressure, temperature, and density profiles using a fully transient wellbore/reservoir simulator. In the proposed approach, perturbations can be created either from static or dynamic well condition. New formulations for these initial conditions for multirate tests with non-Darcy skin are presented. Field examples illustrate the notion presented in this work.
