An experimental study for the determination of the gas fraction and gas velocity in the mud during gas kick control operations was performed. It consisted of two-phase flow of gas-water and gas-mud mixtures through a 14 m (46 ft) fully eccentric annular section of an experimental apparatus. The inclination from the vertical position was varied from 0$\sp\circ$ to 80$\sp\circ$. The results from these tests allowed the evaluation of a previous model for gas bubbles in vertical wells. They also provided support for modifications of that model concerning two aspects: extending its application to slanted wells and improving the simulation in vertical wells with non-newtonian fluids.
