Estimation of Relative Permeability from a Dynamic Boiling Experiment
Abstract/Contents
- Abstract
- Thermal and multiphase flow properties of a Berea sandstone core were estimated by inverse calculation using temperature, pressure, steam saturation, and heat flux data. The development of the two-phase flow region was strongly related to the temperature conditions in the core since heat was the only driving force in the experiment. As a result, the heat input as well as the thermal properties of the sandstone and insulation materials were a major consideration in understanding the system behavior. The high sensitivity of the insulation materials to the observation data and their strong correlation with the other parameters of interest made it difficult to obtain accurate estimates. Although the linear relative permeability model gave the best fit in the two cases presented in the paper, all models yielded similar matches. This indicated that the data did not contain sufficient information to distinguish the different models, giving a non-unique solution.Nonetheless, almost all models gave a consistent estimate for Sgr, which was around 0.1- 0.2. In addition, the choice for the capillary pressure model depended on the condition in the core, whether there was single-phase steam or two phases present. Since the distribution of steam depended heavily on the capillary pressure, the relative permeability would have been more accurately estimated had the capillary pressure been known. The comprehensive analysis of all available data from a transient non-isothermal two-phase flow experiment provided an insight into relation of processes and correlation of parameters.
