Abstract:
A gelled composition for pipeline, flowline, pipeline jumper or flowline jumper dewatering or preventing ingress of seawater into open pipeline systems or components during tie-in operations of jumpers or additional pipe, valving, manifolds, subsea pipeline architecture or flow conduits operations is disclosed, where the composition includes a concentrated metal formate solution and a hydratable polymer. The gelled formate compositions have improved dewatering properties with 100% or 360 pipe coverage. The gelled formate compositions have can also be reused by breaking and reformulation.
