Joe "Bubba" Attryde (right; Transocean Core Tech; USA) and Gregorio "YoYo" Matagnong (left; Transocean Floorman; Philippines) attach the umbilical to the casing above the screen and packer. The umbilical (black tube in YoYo's hand) contains 4 stainless steel tubes. Three tubes connect pressure sensors to the screen and one is used to pump water into the packer to inflate it. The red "centralizer" attached to the casing keeps the screen and umbilical from being damaged while lowering it into the borehole.
