If BP had temporarily abandoned the Macondo well without running the production casing, as it had done with prior wells with narrow drilling margins, BP would likely have had an opportunity to consider other options for setting the casing, such as sidetracking the well and setting the casing in a location with a lower potential for lost returns.
