Abstract
A method for stimulating a reservoir formation while running a casing string into the wellbore includes the steps of: connecting a stimulation assembly to a casing string, the stimulation assembly including a packer actuator in operational connection with a packer and a logging sensor; running the casing string into the wellbore and positioning the logging assembly proximate to a selected reservoir formation; logging the reservoir formation; positioning the stimulation assembly proximate to the reservoir formation; actuating the packer to substantially isolate the reservoir formation from the wellbore; performing the stimulation operation; releasing the packers from sealing engagement with the wellbore; positioning the logging assembly proximate to the reservoir formation; logging the reservoir formation; and disconnecting the stimulation assembly from the casing string.
