There are 2 Targets TuronianAlbian.I have shown some sands to highlightAlbian Abandonment1) Plug #1 to the TOL would give the necessary compliance. (Could say 800ft of cementThe Two reservoir cannot be isolated individually from each other because of a short transition zone/formation.Turonian AbandonmentPlan is to use the unverified TOC.

For planning purposes.I am taking the base of the campanian shale and counting 350m (~1,000ft) which gives the required TOC to be ~2,600m(2,951-350 = 2,601m).

The requirement is for long term abandon the well fit for re-entry should they wish to come back in a success caseBarrier 1 for TuroninanBarrier 2 for TuronianDisadvantage of this option:In case of re-entry ABC will require to drill a lot of cement to be able to use it.7 liner top packer possibly damaged.OPTION 1

Abandonment AssumptionsNot enough separation (>100ft) between the two zones (Turonian and Albian) hence treated as one continuous reservoir.

Procedure:-RIH with cement stinger and B/Plug setting tool.Set and tag and test B/plug @ 2,951m @ Base Campanian Shale.POOH above B/plug and place 800ft /250m combination Plug A. this conforms to two barrier standards.Displace well to inhibited seawater and POOH.RIH with debri cap install and test.POOH, recover riser.Seabed survey and De-mob.Shallow water plug placement set plugs above any aquifer that is not connected to seabed Suggested by Randy.We do not have a continuous sheet of cement across the top. Because we do not cut and pull. So the end objective of isolation of any aquifer cannot be achieved.

Advantage of this OptionShould ABC need to re-enter the well they have to drill only one 800ft cement plug.No possible damage to liner top packer.
