Cemented Monobores

03 October 2007 We are working with a client who is planning 5-1/2" cemented
monobore completion for use with gas wells; the completion will be
very simple, a SSSV and tubing hanger.

Does anyone have any best practices they can share with us and/or
know of anyone who does/can ?

The sorts of things we are interested in are :
1. Use of cement wiper plugs
2. Displacement fluid ; we are thinking of brine
3. Cased-hole clean up : is it necessary ?
4. Is the Hold-Open Sleeve run in the SSSV and left in place when
cementing ?
5. How to avoid build-up of cement around the SSSV profiles
6. Length of shoetrack
7. Has anyone had to rotate the string prior to installation of the
SSSV ?
8. Has anyone rotated the string after the tubing hanger has been
installed and lowering the final distance drillfloor to wellhead ?
9. What length of rathole have you been leaving ?
10. What fluid have you left in the A annulus ?

Thanks
