Drag Reducing Agents (DRA), A New Tool for Improving Subsea Production

Includes a Live Event on 11/17/2022 at 1:00 PM (EST)

The injection of Drag Reducing Agents (DRA), is a valuable tool for pipeline operators to greatly increase the flexibility of a pipeline asset. Their value can be realized all across the pipeline lifecycle, as operational goals change with changing market conditions. DRAs, whose active ingredient is an ultra-high molecular weight polymer, are injected into pipeline fluids to reduce the level of turbulence occurring in the pipe. This effect is quantified by a calculated quantity termed drag reduction. The application of DRA allows operators to maximize their existing pipeline assets by increasing the pipeline flow rate, reducing operational pressures, minimizing operating expense, or a combination of these, all with little or no modification to the asset or other capital expenditure. As the operational goals of the pipeline operator change over the life of the asset, DRA can be applied to meet those changing goals almost effortlessly.

This presentation will cover following topics:  Basic hydraulics, DRA basics, Case studies, and Subsea Injection equipment available.
