Flush Casing Running

Dear All,

We are in serious doubt and have no experience to run the flush connections for the 30” and 24” casing strings mentioned below

1) 30” 234.290 ppf X-56XLF connection or similar

    30" casing setting depth - 2365ft

2) 24” 186.2 ppf L-80 to  XLF connection or similar casing depth - surface to 2910ft.

    24” 201.09 ppf. L-80 to  XLF connection or similar casing setting depth -2910ft - 8235ft.

Flush casing selection is to improve the clearance available. 

Well will be drilled with Surface BOP - Surface wellheads and MLS at sea bed

Water depth is @80ft with 2 million Lbs. Jack up Rig.

Questions:

1) Appreciate if anyone can share the Best practice to deal with this arrangement

2) Is running Flush casing at these depths with these PPF advisable ? Yes / NO - Kindly explain why- Advantages / disadvantages

3)Is the hanging weight of the flush casing at rotary table is an important concern as compared to rotary table capacity. What could be the special casing handling equipment to be ordered

4) Several Casing Manufactures do manufacture these large diameter Flush casing and is available in the market so does that mean it is used world wide and is quite routine operation to run flush casing at depths @ 2365ft for 30"casing & and @ 8235ft for 24" casing ?     

Thanks

Best regards,

Hari.
