ABSTRACT:
Methods and apparatus provide desired levels of continuous fluid pressure in a portion of a wellbore during completion operations. In a described embodiment, a method permits continuous fluid communication between a tubular string extending to the earth's surface and a portion of a wellbore below a packer during testing of the packer. This fluid communication enables a desired fluid pressure to be continually applied to a filter cake lining the portion of the wellbore, to aid in preventing compromise of the filter cake and possible collapse of the wellbore portion. A packer test device included in the apparatus permits such fluid communication during testing of the packer.
