This presentation will review a few practical examples of hydrate remediation activities from Anadarko’s deepwater portfolio. We’ll examine the use of a 3/8” capillary tubing unit to dissolve a hydrate plug on a dry tree well in the deepwater GOM. We’ll also look at pressure disassociation of a hydrate plug in a subsea looped flowline, and chemical dissolution of a hydrate plug in a subsea flowline where pressures were too high to allow disassociation.
