Abstract
A completion apparatus for completing a wellbore includes a tool to alternatively open and close a throughbore; a tool to alternatively open and close an annulus between the outer surface of the completion and the inner surface of the wellbore; a tool to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the annulus; and at least one signal receiver and processing tool capable of decoding signals received. The apparatus is run into the well bore, the throughbore is closed and the fluid pressure in the tubing is increased to pressure test the completion; the annulus is closed and a fluid circulation route is provided from the throughbore to the annulus and fluid is circulated through the production tubing into the annulus and back to surface. The fluid circulation route is then closed and the throughbore is opened.
