H. Designing the Production Casing – Long String versus Liner

BP drilled the Macondo well to a hydrocarbon‐bearing zone and planned
to return to this zone at a later date to complete the Macondo well for
production. Before moving the Deepwater Horizon rig off of the Macondo well,
BP chose to set a production casing that would be used to extract hydrocarbons
at a later date.
