Measurements of produced liquids or gases need to be extremely accurate; small errors add up quickly and create financial risk.
Separators can have very high pressures. An overpressure situation can cause extensive damage to the facility and place workers and the environment in harm's way.
Level control in a separator controls the interface between the water and the oil (liquid hydrocarbons). There must be sufficient time to create a layer of oil above the free water. The water controller controls the interface level by creating a pad between the water and oil. A weir is used to separate the oil from the water and another controller is used to control the oil level. The natural gas flows on the top of the separator. To maintain the interface level and ensure optimal production out of the separator, the instrumentation is integral to the process.
Some separator measurement calculations are not as accurate as you need them to be. Uncertainty and lack of water-cut confidence in allocation data requires you to send employees to the field to validate measurements. This increases HSE risk, and operating costs, and makes it more difficult to maintain your development schedule.
This is required for the allocation of products and produced reporting. Mass, volume flow, density, and temperature are the properties needed for water cut analysis accuracy.
