Faster well startup results in decreased time to net oil
One week reduction in startup time provides up to 8,000 barrels of additional production
Financial gain up to $720K per well
Upstream heat treating of petroleum production fluid to break emulsions into phases of oil, gas and water, plus measurement and monitoring
Midsize North Dakota upstream oil field exploration and production company
Customer was seeking the most time-effective and cost-efficient system to bring wells online and into production. The on-site solution must include technology for separating oil and water as well as accurately measuring and monitoring each component.
The Novaspect / Emerson team of engineers designed and commissioned vertical and horizontal heater treater units equipped with advanced measurement and monitoring capabilities. Their solution resulted in a time savings of up to one week per well with a financial gain of up to $720K per well. A producer commissioning one well per month can deliver up to $8.6 million of additional crude to market. Other benefits include decreased flare gas to storage tanks, significantly reduced shrinkage, and improved allocation measurement, a 28% improvement over conventional methods.

Heater Treater Design Principles
The fundamental principal behind upstream heater treaters is to provide heat to the produced fluid to assist in breaking emulsions combined with sufficient retention time for the oil, water, and gas phases to separate out based on their differences in density. The vessel size is determined by the estimated production volumes and properties of the crude to be treated over the life of the field. There are two types of heater treaters: vertical and horizontal.
Vertical is the most common type of treater due to its low cost, reduced complexity and ability to gravity feed produced liquids to the tanks. Horizontal tends to be more complex and at a higher cost, but a longer “U” style firetube allows for greater heating capacity and treatment rates. Horizontal treaters are more efficient, but typically operate at higher pressures since they lack the vertical height to boost the produced liquids to the tanks.
