Production Optimization

Addressing foam and emulsions to optimize production

To achieve production optimization, it is prudent to put in an effective phase separation program to address the formation of emulsions and foam. The program can also address the cleaning up of produced water for reuse or disposal.

Production Optimization features:

SUEZ’s ProSolv* family of chemical treatment solutions lead the way in paraffin, asphaltene and scale control.

Emulsion Breakers

During the oil and gas production process, oil, water, and emulsifying agents combine with forces of shear and agitation generated in the production process as fluids move from the reservoir, perforations, pumps and valves to form regular emulsions. These are oil external emulsions containing water droplets in the internal phase.

Reverse Emulsion Breakers / Water Clarifiers

Water is often produced in oil & gas systems. The water, oil & condensate, and emulsifying agents, along with agitation and shear from the production process, often creates a water external or "Reverse Emulsion" with oil droplets as the internal phase. This creates lost production revenue because oil is removed with the water, but it also becomes a challenge based on the final disposition of the water. Depending on its final use or discharge, the water will require additional purification to remove the oil or hydrocarbons to meet specifications set by production companies and environmental regulatory agencies.

Defoamers / Antifoamers

In oil & gas production problems, foam can become a production challenge in several areas, including separation systems, dehydration units, H2S / CO2 scrubbers and in water treatment systems. When foam forms, there is potential for spills due to overflowing, process disruptions and liquid carryover, in addition to reduction in the capacity of the treating system.

Foamers

Maximize production by removing liquids from the well

When a well is drilled and put into production service, it will go through a natural decline cycle. Initially, the well may be free flowing as the reservoir pressure is sufficient to push all gas and liquids to the surface. Over time, the reservoir pressure lessens and liquids tend to accumulate downhole, eventually affecting production. The fluid pressure in the production tubing may become greater than the reservoir pressure and production stops until the reservoir has time to pressure up enough to overcome the fluid pressure. The accumulation of liquids downhole is referred to as liquids loading.
