<p>A method for completing a wellbore (1) comprises operating a) a tool (15) to alternatively open and close a throughbore (40) of the completion (4); b) a tool (13) to alternatively open and close an annulus (5) defined between the outer surface of the completion and the inner surface of the wellbore; c) a tool (11) to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the said annulus; and d) at least one signal receiver and processing tool (9) capable of decoding signals received relating to the operation of tools a) to c). The method entails running the apparatus is run into the well bore, and tool a) is operated to close the throughbore; the pressure within the fluid in the tubing is increased to pressure test the completion; tool b) is operated to close the annulus; tool c) is operated to provide a fluid circulation route from the throughbore to the annulus and circulate fluid through the production tubing and out into the annulus and back to surface; tool c) is then operated to prevent the fluid circulation route from the throughbore to the annulus such that fluid is prevented from circulating; and tool a) is operated to open the throughbore.</p> |
