Abstract
The present work aims at the experimental determination of the isothermal compressibility of drilling fluids under high pressure and high temperature. For that, a high-resolution PVT (Pressure-Temperature-Volume) cell was used to measure data through the Constant Composition Expansion method. The isothermal compressibility values of the studied fluid were similar to the data found in the literature.
