Method of and apparatus for completing a well
First Claim
1. An apparatus comprising:
- a downhole barrier tool to alternatively open and close a throughbore of the apparatus;
a downhole packer tool to alternatively open and close an annulus defined between the outer surface of the apparatus and the inner surface of a wellbore;
a downhole circulation tool to alternatively provide and prevent a fluid circulation route between the throughbore and the annulus above the downhole packer tool;
a downhole signal receiver and processing tool that decodes wireless signals received to operate at least one of the downhole barrier tool, the downhole packer tool, and the downhole circulation tool; and
wherein the circulation tool is located below the signal receiver and processing tool, and both the packer tool and the barrier tool are located below the circulation tool.

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.

16. A method comprising:
-
i) running in an apparatus into a wellbore, the apparatus being provided at a lower end of a production tubing which is adapted to selectively contain fluid at pressure, the apparatus comprising; a downhole barrier tool to alternatively open and close a throughbore of the apparatus; a downhole packer tool to alternatively open and close an annulus defined between an outer surface of the apparatus and an inner surface of the wellbore; a downhole circulation tool to alternatively provide and prevent a fluid circulation route between the throughbore of the apparatus and the annulus; and a downhole signal receiver and processing tool that decodes wireless signals received relating to the operation of the downhole barrier tool, the downhole packer tool, and the downhole circulation tool; ii) operating the downhole barrier tool to close the throughbore of the apparatus; iii) increasing a pressure within the production tubing; iv) operating the downhole packer tool to close the annulus; v) operating the downhole circulation tool to provide a fluid circulation route between the throughbore of the apparatus and the annulus; vi) operating the downhole circulation tool to prevent the fluid circulation route between the throughbore of the apparatus and the annulus; and vii) operating the downhole barrier tool to open the throughbore of the apparatus. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
