Re-entry Exploration well without Mud Line Hanger

26 September 2019 Dear all,

We have drilled 2 Exploration well and the well was temporarily P&A without the Mud Liner Hanger system in 2015 & 2016, and now we are planning to re-entry these 2 wells to develop them.

Has anyone have experience with this case? if so, could you please kindly share with us how would you tie back the casing? What is the pros and cons? and how we can make sure the production casing integrity? 

So far, we are thinking to overdrive the conductor with bigger casing and use tie-back casing packer for 13-3/8" & 9-5/8" Casing.
How is the realibility of these tie back packer for the upcoming production? 

Attached are the final P&A schematic for both wells.

Appreciate your inputs & comments.

Regards,
Juliana M.
