Pig/paraffin obstruction remediated in a deepwater subsea tieback of the Gulf of Mexico’s Cottonwood field
The flow assurance team used solvent soaking and controlled pressurization techniques to release a pig/paraffin obstruction, and then applied an innovative process of flowline cleaning with a solution of dispersant and sea water at 12% of the cost of replacing the obstructed flowline.
