Drilling and completion

Dear fellow members

I got the following from my friend in Algeria and they're thinking about running ABL.....

"We have a hole problem plenty cavings and big size, the hole not stable And we want to run 7" liner 1350 meters in open hole!

No way to cement this liner! We will get pack off on hanger and PBR as well We had a pocket below 9⅝" shoe and the 8½" section started after 50m below the shoe.

That means bellow shoe we have a 12¼" hole for 50 m then started 8½"

This all pocket is claystone The inclination is 3.5° degree And drilled 30m with RSS and got vertical That mean 3°/100ft dogleg.

SO WHAT DO YOU THINK HERE ?! URGENT MATTER"
