Reverse Cementing

Hi,

we are planning a reverse cement Job for 24" casing run in 28" hole size, the previous casing is 26" - ID - 25"

26" casing setting depth - 2700ft

24" casing setting depth 3650ft.

The Top of cement behind 24" casing is 2300ft. covering a big loss zone.

FG at 24" casing depth 10.5ppg

MW drilling was 9.1 ppg

I appreciate your help understanding what way to go- Conventional cementation or Reverse cementing.

What are the Hi-points or Low points for Both.

What is achievable having good cement bond behind casing covering the loss Zone.

If anyone has case studies , SPE papers kindly share.

Appreciate your help

Thanks & Best Regards,

Hari.
