Engineering design and fabrication of equipment for onshore and offshore production facilities has been the mainstay of EN-FAB’s business. EN-FAB personnel are particularly adept in design, engineering, and construction of production equipment such as; 2 & 3 phase separators, heater-treaters, desalters, demulsifiers, glycol dehydration units, fuel gas skids, vapor recovery units, etc. Qualified service technicians are available for start-up service and commissioning. This combination of unique abilities has enabled EN-FAB, Inc. to be a leader in supplying Early Production Facilities and Systems.

An early production facility is a complete facility to produce oil and gas and dispose the produced water. This facility is usually located on land, but barge facilities are also common. The size range is usually between 5,000 to 60,000 barrels per day. All the equipment for treating the oil, gas, and water such as separators, heaters, scrubbers, power supplies, lighting, water treatment, etc. is provided as a package. The facility is usually all skid-mounted and is put in place, interconnected, and commissioned by EN-FAB, Inc. Early production facilities are becoming very important to the oil companies due to the necessity to get a field or some part of the field on line and producing in a minimum amount of time. EN-FAB can provide a complete production facility in short time, including all the equipment to treat the oil, gas, and water, plus the equipment for power generation, lighting, control rooms and site design.

The heater treater is normally found downstream of a two-phase separator on a high pressure system. It can be found downstream of the well, a free-water knockout or gun barrel on a low pressure system. Heater treaters are used where the emulsion cannot be broken using just retention, quiescence and chemical demulsifiers. The addition of heat is required to break the emulsion. Heat lowers the viscosity of the oil making it easier for the water to settle. It also creates molecular movement which aids in the coalescing of the water droplets. The incoming emulsion enters the vessel near its top and any gas associated with the emulsion is vented. Any free water immediately drops to the water section where it is discarded. The emulsion flows over the fire tubes where it is heated to the desired temperature as it rises through the heated water section. (The heated water serves to wash the emulsion and to aid in the coalescing of the water droplets.) The emulsion and oil continue to rise into the oil treating section of the vessel where the emulsion breaking process continues. Some treaters are equipped with a "hay" or excelsior section to aid in coalescing the water droplets and to act as a filtering media for removal of solids from the crude oil. The heights of the water and oil columns are controlled by dump valves or by a siphon. The clean oil exits the vessel near the top third of the vessel and the water is drawn off directly under the fire tubes and emulsion distribution pan.
