Wellbore gas loading has been used since the 80's to generate small fractures to overcome near wellbore damage. Two techniques are currently used. The first uses a propellant tool to dynamically pressurize the formation whereas the second store the fracturing energy through the well pressurization before the casing perforation and the fracture initiation. These two techniques are reviewed and laboratory...
In this paper, we have presented a numerical model for the dynamics of a two-dimensional bubble rising through a viscous fluid. Unlike previous attempts in the literature, we have combined the growth of the boundary layer with the evolution of the bubble shape. This results in a coupled set of algebraic and differential equations. The computed shape from the numerical solution agrees well with physical...
