The example is from a subsea infrastructure that was experiencing flow assurance challenges due to both hydrate and paraffin formation. The condensate had a paraffin content of 14.5 wt%. Paraffin control chemicals were being deployed with limited success. This paper gives a detailed description of the flow assurance root cause failure analysis in a Gulf of Mexico production system that was experiencing severe hydrate and paraffin failure. Details are given on the experimental work performed to develop new products, as well as results of the field applications. The paper summarizes the implementation and ongoing monitoring of this program in the field and provides lessons learned. Details on the cost savings created in reduced operations and chemical overhead for the operator are given, along with the value savings due to no lost production since blow downs were no longer required.
