Estimating the significance parameters, such as skin factor, permeability, wellbore storage coefficient, are
the most component of transient pressure analysis. Many optimization algorithms have been applied to
parametric estimation and realized the minimum error of well test curve. Although a flexible heuristic
particle swarm optimization can hunt optimal solution rapidly, it is difficult to search further in the
vicinity of the optimal solution. Hence, to alleviate the local optimum and premature convergence, a
global hybrid algorithm referred to as particle swarm simulated annealing is proposed, and proves to
have better performance of convergence and accuracy than traditional methods, which are more suitable
for parameter estimation
