Gravity Separation

Most oil-treating equipment relies on gravity to separate water droplets from the oil continuous phase, because water droplets are heavier than the volume of oil they displace. However, gravity is resisted by a drag force caused by the droplets’ downward … Continue reading

Demulsifiers

Chemical demulsifiers sold under various trade names, such as Tretolite ™, Visco™, and Breaxit™, are highly useful in resolving emulsions. Demulsifiers act to neutralize the effect of emulsifying agents. Typically, they are surface active agents and thus their excessive use … Continue reading

Emulsifying Agent

When thinking about emulsion stability, it may be helpful to realize that in a pure oil and pure water mixture, without an emulsifying agent, no amount of agitation will create an emulsion. If the pure oil and water are mixed … Continue reading

Forming Emulsions

For an emulsion to exist there must be two mutually immiscible liquids, an emulsifying agent, and sufficient agitation to disperse the discontinuous phase into the continuous phase. In oil production, oil and water are the two mutually immiscible liquids. An … Continue reading

Oil Treating System

Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the most desirable methods of treating the crude oil to contract requirements. Some of these factors … Continue reading

Horizontal Three Phase Separator Part 2

Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the oil and water flow over weirs where level control is accomplished by a simple displacer … Continue reading

Horizontal Three Phase Separator Part 1

Three phase separator are designed as either horizontal or vertical pressure vessel. Figure 5-2 is a schematic of a horizontal separator. The fluid enters the separator and hits an inlet diverter. This sudden change in momentum does the initial gross … Continue reading

Gas Lift

We must comment a bit about gas lift systems because they are in widespread use and have a significant impact on the facility process. Figure 2-19 is a diagram of a gas lift system from the facility engineer’s perspective. High-pressure … Continue reading

Well Testing

It is necessary to keep track of the gas, oil, and water production from each well to be able to manage the reserves properly, evaluate where further reserve potential may be found, and diagnose well problems as quickly as possible. … Continue reading

Gas Dehydrator

Removing most of the water vapor from the gas is required by most gas sales contracts, because it prevents hydrates from forming when the gas is cooled in the transmission and distribution systems and prevents water vapor from condensing and … Continue reading
