An improved process for optimizing the stimulation of an entire target formation of an oil or gas well during fluid treatment is obtained by dividi ng the target formation (110) into intermediate zones (120, 130, 140) and initiating stimulation in each intermediate zone (120, 130, 140). Once stimulation is initiated in each intermediate zone (120, 130, 140), ball sealers are used to block the casing perforations (150, 160, 170) at the intermediate zone (120, 130, 140) and divert fluids to another intermediate zone (120, 130, 140). After stimulation has been initiated in all intermedia te zones (120, 130, 140), the ball sealers are removed from the perforations (150, 160, 170) and treatment of the entire target formation (110) is conducted.
