Adjusting Relative Permeability Measurements to History Match Water Production in Dynamic Simulation Models

Most of field development plans need a countable simulation model. Simulation models are considered dependable when they match all aspects of the field’s history -performance. This is achieved by matching pressure data and production phases of oil, water and gas production and injection. Many factors affect the process of history match. The most important factor is the relative permeability, which affects the partial flow of fluid phases through rock conduits. Measuring relative permeability and adjusting it to be included in simulation model is our focus in this work. Field ’X’ is in our interest in this study. The field is under of water flooding implementation. After water-floodi ng project has been started, field ‘X’ suffered from high water cut (W.C) rates in large oil producers and low oil production rates. This urged to restudy the field and consequently we needed to build a full simulation model with a proper history-match. Special Core Analysis test with unsteady-state displacement experiment for relative permeability measurement has been performed for well ‘X - 4’. In this paper, we will show you how to process relative permeability data and adjust them to be introduced into simulation model to achieve a good history match performance.
