Drag Reducing Agents and Flow Improvers

DRAG REDUCING ADDITIVES (DRA’s) AND FLOW IMPROVERS

Westhaven Energy Company Ltd. manufactures drag reducing agents used in the oil and water pipeline industries. Westhaven Energy Company Ltd.’s  range of advanced and unique chemistries can improve flow rates, reduce pressure and/or reduce the power necessary to move fluids through pipelines.

 

 

 

 

SERVICE AND TECHNICAL EXPERTISE

 

Under certain operating conditions, flow improvers can reduce internal pipe turbulence thus allowing improved flow.  in the client’s oilfield operations to help determine the most effective and economical product. Based on this test and field simulation, we will recommend a specific product.

 

 

 

 
DRAG REDUCING ADDITIVES (DRA’s) AND FLOW IMPROVERS - GENERAL DISCUSSION

 

 

Westhaven Energy Company Ltd. Drag Reducing Additives (DRA’s) can improve the flow in pipelines by reducing turbulence. Westhaven Energy Company Ltd. DRA’s can dramatically increase flow, or reduce pressure loss or sustain a given flow rate using less  pump energy.

In most oil pipelines, flow is either turbulent. Or in the transition zone.  This turbulence and frictional resistance, consumes most of the energy applied to move the fluids. Westhaven Energy Company Ltd. DRAs are long chain polymers that reduce friction near the pipeline wall and within the turbulent core, dampening the turbulence and decreasing energy loss thereby allowing the pipeline operator to either increase the volume with a given pump size, or reduce the pump pressure in the pipeline, or allow reduction in booster pumps.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  • Westhaven Energy Company Ltd. Drag Reducing Agents (DRA) offer flow improvement effectiveness at low concentrations by changing the flow when it is in the                                                             transitional or turbulent state, back to a                                                           laminar flow! This reduces energy and                                                             pressure loss in the pipe.

 

 

 

The most common use of Westhaven Energy Company Ltd.'s DRA is to increase pipeline flow rates in a system that is at capacity. In order to deliver more fluids in the system, the DRA is injected into the oil to increase the overall pipeline capacity. DRA usage is very cost effective versus capital intensive mechanical expansion. The DRA dosage is typically in parts per million and the cost is minimal per incremental barrel of oil produced and there is no need to spend significant capital investment in either pumps, pipelines or costly infrastructure.

 

 

 

In many cases, due to age, Pipeline Operators want to decrease the pipeline pressure in order to extend the life of an aging or partially corroded pipeline. By using Westhaven Energy Company Ltd. DRA’s, the same flow volumes can be maintained at lower pressures

 

  • Westhaven Energy Company Ltd. Drag Reducing Agents (DRA) offer Energy Savings at low concentrations

Drag Reducing Agents can be used to reduce the pump horsepower necessary to move a given fluid volume through a pipe. This may allow a pumping station to be bypassed either permanently or temporarily for service or repair.
