摘要：Methods and apparatus provide desired levels of continuous fluid pressure in aportion of a wellbore during completion operations. In a described embodiment, amethod permits continuous fluid communication between a tubular string extending tothe earth's surface and a portion of a wellbore below a packer during testing of thepacker. This fluid communication enables a desired fluid pressure to be continuallyapplied 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 packertest device included in the apparatus permits such fluid communication during testing ofthe packer.
